- How are the size of cation and anion related to corresponding neutral atoms
Answers
Explanation:
size of cation is always less than neutral atom ..
because it lose electron so no of proton increase ...nuclear attration increase ..and size decrease
size of anion is always greater than neutral atom
it gain electron ...in electron electron repulsion occur ..and nuclear attraction also less
if we make order of size
anion >neutral> cation
Explanation:
Cation:-
Cation is formed by the loss of electron(s),hence proton(s) are more than electron(s) in a cation.So electrons are strongly attracted by the nucleus and are pulled inward.Hence the size of Cation gets smaller than neutral atom.
Anion:-
Anion is formed by the gain of electron(s). Thus,the number of electron(s) are more than proton(s). The effective positive charge in the nucleus is less, so less inward pull is experienced.Hence, the size of Anion is always greater than a neutral atom.
