Classify the elements of the third period into metals and non-metals.

____block elements contains non-metals, metals and metalloids.

Following rule, in general, classifies p- block elements into metals, non metals and metalloids, where P is the period number and N, the valence electrons. (P+1) gt N, the element would be a metal. (P+1) lt N, the element would be a non-metal. (P+1) = N, the element would be a metalloid Classify the following into metals, nonmetals and metalloids: Z= 14, 31, 35,54
