Question

Predict the formula of binary compound that would be formed by Phosphorus and
chlorine.
a) P2Cl5
b) ClP3
c)PCl5
d)None

Answer 1

Explanation:

(i) Alkali metal lithium (with 1 valence electron) combine with group 16 element oxygen (having valence of 2) to  form Li2O.

(ii) Alkaline earth metal magnesium (with 2 valence electrons) combines with group 5 element nitrogen (having valence 3) to form Mg3N2.

(iii) Group 13 element aluminum (with 3 valence electrons) combines with group 17 element iodine (a halogen with valence 1) to form AlI3.

(iv) Group 14 element silicon (with a valence of 4) combines with group 16 element oxygen ( having valence 2) to form SiO2.

(v) Group 15 element phosphorous (with valence 3 or 5) combines with group 17 element fluorine (a halogen with valence 1) to form PF3 or PF5.

(vi)  Element 71 with 3 electrons in the valence shell (4f145d16s2) combines with group 17 element fluorine (a halogen with valence 1) to form EF3 where E is the symbol of the element
