Textbook Problem

Give the periodic group number and number of valence electrons for each of the following atoms.

  1. (a) C
  2. (b) Cl
  3. (c) Ne
  4. (d) Si
  5. (e) Se
  6. (f) Al

(a)

Interpretation Introduction

Interpretation: The periodic group number and number of valence electron for the given atom should be identified.

Concept Introduction:

Periodic Table: The available chemical elements are arranged considering their atomic number, the electronic configuration and their properties. The elements placed on the left of the table are metals and non-metals are placed on right side of the table.

In periodic table the horizontal rows are called periods and the vertical column are called group.

There are seven periods and 18 groups present in the table and some of those groups are given special name as follows,

Group-1Alkali metalGroup-2Alkaline metalsGroup-16ChalcogensGroup-17HalogensGroup-18Noble gases

Valence electron: The electron is considered as valence electron if it present in outermost shell of atom which gets involved in the formation of chemical bond.

Explanation

Analysing the periodic table shows, that Carbon (C) ato...
