Question

Q 10 : How does an element
with atomic number 13 forms
a stable charged ion?​

Answer 1

Explanation:

The element is Aluminium. It forms a stable charged anion by losing 3 electrons.

Al - 3e⁻ = Al³⁺

Hope it helps.

Answer 2

Answer:

By giving three electrons

Explanation:

We Know that aluminium has atomic number 13. Now its electronic configuration would be

2-8-3

Since its valence electrons = 3 i.e. < 4

So, it has a capability to lose 3 electrons and form a trivalent cation i.e. Al³⁺

Example

Aluminium Oxide = Al              O

                                  3               2

Formula = Al 0

                                  2   3
