hmm...what Just happened here? not good....am lot quite sure this answer is right



metals are known to give off electrons easily..huh?



and we all know that there is increase in the metallic property down the group..



so from my analysis of the question...the answer was supposed to be A

pls someone correct me somewhere...help needed



all the best

The answer should be A...
Reactivity of the alkali metals increase down the group and therefore the element lower in the group loses electrons MOST readily

The period an element belongs to is determined by the number of shell it has,an element that has one shell belongs to period 1 for example.

The element with more shells doesn't feel the nucleuses force of attraction in it's outer shell as much as the elements with lesser shells and so doesn't require much energy to remove the electron in it's outer shell compared to the latter.

from my distinctly research, The elements in the same group of the periodic table have the same number of valence electrons(Valence electrons are the electrons located in the outermost shell of an atom that are involved in chemical bonding). The valence electrons determine the reactivity and chemical properties of an element. In this case, all four metals are in the same group and have the same number of valence electrons. However, as we move from left to right across a period, the atomic radius decreases and the effective nuclear charge (the attractive force experienced by the valence electrons from the nucleus) increases. This makes it harder for the valence electrons to be removed from the atom, so the ionization energy (the energy required to remove an electron) increases. Therefore, S, which is in period 6 and has the highest effective nuclear charge, loses electrons least readily. The correct answer is S in option (D)

Metals at the bottom of a group lose electron easily than those at the top.
They lose electron easily because they have low ionization energy.
low ionization energy causes valence electron to be held loosely to the shell, which is vice versa for high ionization energy. Ionization energy increases across the period and decreases down the group
The answer should be A
