state the vacancies of aliuminium, Zinc, iron and calcium?
Answers
Answer:
Valency of aluminium is: Atomic number of aluminium is 13 so its electronic configuration is 2, 8, 3. Since it has 3 electrons in its valence shell, ...
Aluminium : +3
In outermost shell zinc is the fourth shell, n=4 , has two electrons. This means that zinc can lose the two electrons located in the 4s-orbital to become the Zn2+ ...
zinc : +2
The atomic number of iron is 26. Its electronic Its electronic configuration =2 8 8 8 Then how its valency is 2+ and3+ ·
Iron : 2,3
The valency of calcium is 2+. Calcium has 2 electrons in its outermost shell ,its electronic configuration being (2,8,8,2).In order to attain stability it loses 2 ...
Calcium : 2
