What is the formula unit for a compound made from Pb4+ and oxygen?
1 answer:
Answer : The formula unit of compound will be,
Explanation :
As we know that one atom of oxygen contains (2-) charge and one atom of lead contains (4+) charge. So, to balance the of charges of lead, the 2 oxygen atoms combine with the 1 lead atom. Thus, the compound formed will be, .
That means, when combine with oxygen that is,
, it gives
by the criss-cross method.
Criss cross method : It is a method of determining the chemical formula.
The formula unit is a shown below.

Answer : Ionic compound is created when potassium and chlorine combine. The chemical formula of the compound is KCl.
Explanation :
When potassium and chlorine combine then the type of compound created is Ionic compound.
Ionic compound : These are those compounds which are made of a metal element and non-metal element. Salts are ionic compound which consists of a positive and negative ions.
The electronic configuration of Potassium is,
The electronic configuration of Chlorine is,
From this we conclude that the potassium atom is a metal which has 1 electron in their valence shell and chlorine atom is a non-metal which has 7 electrons in their valence shell. For the complete octet, chlorine atom needs only 1 electron which it receives from the potassium atom.
During this process, potassium atom will loses 1 electron and acquire positive charge and chlorine atom will gain 1 electron from potassium atom and acquire negative charge.
The chemical formula of the compound is KCl.
