Classification of Elements and Periodicity in Properties
Predict the formula of the stable binary compounds which would be formed by the following pairs of elements:
(i) element 114 and fluorine
(ii) element 120 and oxygen.
(i) Element 114 belongs to group 14 with a valence of 4. Fluorine belongs to group 17 with a valence of 1. Hence the formula of the compound formed would be Uuq. I4.
(ii) Element 120 belongs to group 2 with a valence of 2. Oxygen belongs to group 16 with a valence of 2. Hence the formula of the compound formed would be Ubn.O.
