The number of metals, metalloids, and non-metals present in the third period of the Periodic Table should be determined. Concept Introduction: Periodic Table contains periods and groups. There are 18 groups and 7 periods in the periodic table. The vertical columns are known as groups and horizontal rows are known as periods. The numbering of periods is done as 1 to 7 from top to bottom and groups are named as 1A, 2A, 3B to 8B, 1B, 2B, 3A to 8A from left to right where A represents representative elements and B represents transition elements . Elements in the same family have similar chemical and physical properties. In periodic table, elements are classified as metals, non-metals or metalloids. Metals are good conductor of electricity and can be mould into different shapes without breaking whereas non-metals are bad conductors of electricity which are present on the right hand side of the periodic table and can’t be mould into different shapes. And, the elements which have properties of both metals as well non-metals or the elements with properties lie between metals and non-metals are said to be metalloids.

Interpretation Introduction

Interpretation:

The number of metals, metalloids, and non-metals present in the third period of the Periodic Table should be determined.

Concept Introduction:

Periodic Table contains periods and groups. There are 18 groups and 7 periods in the periodic table. The vertical columns are known as groups and horizontal rows are known as periods.

The numbering of periods is done as 1 to 7 from top to bottom and groups are named as 1A, 2A, 3B to 8B, 1B, 2B, 3A to 8A from left to right where A represents representative elements and B represents transition elements. Elements in the same family have similar chemical and physical properties. In periodic table, elements are classified as metals, non-metals or metalloids.

Metals are good conductor of electricity and can be mould into different shapes without breaking whereas non-metals are bad conductors of electricity which are present on the right hand side of the periodic table and can’t be mould into different shapes. And, the elements which have properties of both metals as well non-metals or the elements with properties lie between metals and non-metals are said to be metalloids.
