Question

tandency to form cation
complete the anology​

Answer 1

Answer:

Every element has a tendency to become stable by attaining the octet configuration. Most metal have less than 4 electrons in their valence shell. ... That's why it is easy to lose less than 4 electrons than to gain more than 5 electrons. This is the reason why they have a tendency to form cations by losing electrons.

Answer 2

Explanation:

Alkali metals and alkaline earth metals such as Cs, Ba and K are highly electropositive metals with low ionization energy. They attain inert gas configuration on formation of cations. Hence, they have strong tendency to form cations.
