Sodium is a very reactive metal; it is, in fact, second in the reactivity table of elements. Beryllium is less reactive (with regards to ease offormation of a positive ion/cation of the metal) than magnesium. If this valence electron is lost, then noble gas configuration is obtained. 5 years ago. a. we learn to be deviant through our interactions with others who break the rules. Potassium , sodium and lithium are alkali metals which belong to Group 1 of the periodic table while calcium and magnesium are the alkaline earth metals belonging to Group 2. The comparative reactivity of these metals is K > Na > Ca. Sodium easily lose electrons than magnesium and get oxidized to easily. increase down the group, meaning that the element could be Ca or Sr. That is because Sodium it is more up in the scale unlike Magnesium. Choose all that apply. This is because sodium has half filled orbital (that's 1 electron at 3s orbital) while magnesium has completely filled orbital (that's 2 electrons at 3s orbital). b. it offered free land to those will...

Calcium is above sodium in the activity series, and is therefore, more reactive than sodium, yet calcium reacts much more slowly with water than does sodium. no,aluminium is more reactive than magnesium because aluminium has partially-filled p-orbital. Amina needs to get the facts right. © 2021 Education Expert, All rights reserved. Calcium is above sodium in the activity series, and is therefore, more reactive than sodium, yet calcium reacts much more slowly with water than does sodium. This is also indicated by more negative standard electrode potential of K ( -2.925V) as compared to Na ( – 2.714 V) . 64 b. How reactive is sodium metal? a. it set up reservations for freed african americans. The further down a group an atom is, the larger the atom is, and the more reactive the element is. the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. Why is sodium more reactive than copper? Zinc is more reactive than copper thus it replaces copper in this reaction. in case of alkali metals there is one electron in the outermost shell. The purpose of test marketing is to: select one: a. assess how well various aspects of the marketing mix fit together. Potassium, sodium and lithium all react quickly with cold water to produce a metal hydroxide and hydrogen gas. Magnesium must lose two, and the second ionisation energy is much higher than the first because it involves pulling a negative electron away from a positive ion which is clearly more attractive than a neutral atom. Reactivity Tests & Extraction. Sodium reacts by losing a single electron. ... Basically magnesium is more reactive than zinc because it displaces it in a reaction. Na has only one valence electron, so it readily donates that electron to other atoms to achieve an octet. Why is sodium more reactive than magnesium. ​social organization, a subjective un... View a few ads and unblock the answer on the site. Similarly, atoms of potassium (K in the table) are larger, and so more reactive, than atoms of sodium. Answer is: Lithium (Li) is less reactive than potassium (K) because the valence electrons in lithium atoms are closer to the nuclei and harder to remove. Copper cannot replace Zinc as it is less reactive. The volume of 1.00 mile of water is how many milliliters. I disagreed with him, because potassium is more electropositive than lithium and thus more reactive. The reason why Sodium is more reactive is because it only has to lose one electron to react. Atoms of sodium (Na in the table) are larger, and so more reactive, than atoms of lithium (Li in the table). Zn undergoes more easily than Copper. select all of the information you need when getting a quote for car insurance. In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest. 60 b. It takes extra energy to remove the second electron. Magnesium + copper sulfate → magnesium sulfate + copper. also, polar chemical often dissolve polar... How did the united states change its approach to science after the soviet union launched sputnik 1 in 1957? magnesium + hydrochloric acid → magnesium chloride + hydrogen Mg(s) + 2HCl(aq) → MgCl 2 (aq) + H 2 (g) The more reactive the metal, the more rapid the reaction is.

Earth alkaline metals (group 2), in this example strontium, have higher ionization energy than alkaline metals, because they have two valence electrons, they are less reactive. Explain the reactivity differences of K, Na and Ca based on their atomic . Magnesium must lose two, and the second ionisation energy is much higher than the first because it involves pulling a negative electron away from a positive ion which is clearly more attractive than a neutral atom. Explain the reason for this change in size. use the following formula to compute the partial pressure of the butane. It has one valence electron which is removed easily, making it highly reactive. 1 decade ago. certainty 4: Strontium is softer than calcium and much extra reactive in water. You can actually burn magnesium in a way that you can't aluminium. Q2 : In what ways lithium shows similarities to magnesium in its chemical behaviour? Mantles for gas lanterns contain thorium, because it forms an oxide that can survive being heated to incandescence for long periods of time. Potassium has lower first ionization energy than lithium, so potassium easier remove one valence electron. (pbutane =patmosphere - pwater) pbutane =. the speed of light is 2.9979 x 108 m/s. sodium is more reactive than magnesium! convert to mmhg by multiplying by 25.4. record answer in data table. My friend claimed lithium to be more reactive than potassium due to its position in the reactivity series of metals: $$\ce{Li > Cs > Rb > K > Ba > Sr > Ca > Na > Mg}$$ Then we found out that potassium reacts indeed more violently in water. Viewed 137 times 3 $\begingroup$ I reacted about $0.25 \,\mathrm{g}$ of magnesium, sodium and lithium in $20 \,\mathrm{ml}$ of $2 \,\mathrm{M} \,\ce{HCl}$ at room temperature. 9) Explain how lithium and potassium follow the same pattern. Thus No reaction occurs when Copper reacts with Zinc sulphate, We can observe this in the reactivity series or electrochemical series which is as follows. Rubidium electron configuration: ₃₇Rb 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶5s¹; one valence electron is 5s¹ orbital. When 2-bromo-2-methylbutane is treated with a base, a mixture of 2-methyl-2-butene and 2-methyl-1-butene is produced. to do this, use the chart listed below and record the partial pressure of the water vapor, pwater, at the temperature you recorded. potassium is more reactive than Mg because both lie in the same group and the element potassium has more electropositivity than magnesium. Magnesium hydroxide is formed as a very thin layer on the magnesium and this tends to stop the reaction. How was the speed of light determined and what is it's value? Cancel anytime. 10) Do you think that magnesium would be more reactive or less reactive than sodium? Electron configuration of potassium is: ₁₉K 1s²2s²2p⁶3s²3p⁶4s¹.

In addition, the two electrons are in a filled s subshell, which has added stability. Sodium metal is more reactive than magnesium metal because it is easier to lose electron from the 3s orbital of sodium atom than that of magnesium. Mg(s) + CuSO4(aq) → MgSO4(aq) + Cu(s) Platinum, however, is less reactive than copper and so cannot displace copper from a copper sulfate solution.

Those are the main factors that explain why sodium metal is more reactive than magnesium metal Ask Question Asked 4 years ago. 0 2. eda. Since sodium melts at a low temperature, it melts when it reacts with water. The more reactive a metal is, the more likely it is to from ions and force others out. 0 0. Magnesium reacts by losing two electrons. 8) Using the observations from sodium and water and your answers from the previous two questions, explain why sodium is so reactive. Losing each electron requires some energy to be put in, so it is easier for sodium to react than magnesium, and easier for magnesium to react than aluminium. The subscriptoin renews automaticaly until you cancel. Amina needs to get the facts right. Calcium, Ca, is less reactive than sodium. Compare Magnesium and Sodium on the basis of their properties, attributes and periodic table facts. Sodium is more reactive than Calcium. Oxidation is loss of electrons by an atom or a species.
