Chapter 2, Problem 41E

Interpretation Introduction

Interpretation: The chemical symbol, atomic number and position in the periodic table of each given element are to be stated. If these elements are metal, metalloid or non-metal is to be stated.

Concept introduction: In modern periodic table, elements are arranged in groups and periods according to their atomic number. Metals are present at left of the stair step, whereas nonmetals are present at right of the stair step. Metalloids are present inside the stair step.
