Question

Which ionic compound is expected to form from combining the following pairs of elements:

(a) Barium and fluorine,

(b) Cesium and chlorine,

(c) Lithium and nitrogen,

(d) Aluminum and oxygen?

Answer 1

Ionic bonding will form when the bonding is between a METAl and anon-metal.

 

Thus

Part (a) Barium and fluorine combine to form BaF2

Part (b) Cesium and chlorine combine to form   CsCl

Part (c) Lithium and nitrogen combine to form Li3N

Part (d) Aluminium and oxygen combine to form Al2O3.

Ionic bonding will form when the bonding is between a METAl and anon-metal.
