Question

Which of the following ion is formed by loss of electron from its p-orbital???
Answer is Al+3 electronic configuration?

Option A :
F-1

Option B :
Mg2+

Option C :
Al3+

Answer 1

Answer:

[Ne] 3s² 3p¹

Explanation:

10 electrons

Al3+ indicates an ion of aluminum having a charge of + 3. I.e., since an aluminum atom normally has 13 protons and 13 electrons, this ion has 10 electrons (-10 charge) and 13 protons (+ 13 charge) giving it a charge of + 3 (-10 + 13 = +3).
