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
