Question

Two atoms X and Y have 11 and 18 electrons respectively. Which of them is likely to become a cation? Why?​

Answer 1

Answer:

Atomic no 11 will have the highest metallic property which is sodium.

Atomic no 8 is oxyzen

When sodium reacts with Oxyzen it will form. Na^2O

Answer 2

Answer:

Atoms are stable when they've 2 or 10 or 18 electrons.

If an atom has 11 electrons then it needs to lose 1 electron to become stable, when an atom loses an electron it gets a positive charge.

If an atom has 18 electrons it is a stable element.

so atom having 11 electrons is a cation
