Question

How many electrons does an aluminium atom lose during the formation
of ionic compound?
(a) 1
(b) 2
(c) 3
(d) 4​

Answer 1

Answer:

ANSWER OPTION (C)

Explanation:

* The Aluminium atom loses 3 electrons and each Fluorine atom gains 1 electron to get their nearest inert gas: Neon's configuration, [He]2s22p6. * Thus formed Al3+ and three F- ions combine together to give AlF3. * The electrovalency of Al is 3 and that of F is 1.
