Question

Explain why groups 14 and 15 are better representatives of mixed groups than groups 13 and 16

Answer 1

Answer;

Groups 14 and 15 each contain metals, nonmetals, and metalloids while Group 13 contains metals and a metalloid, and Group 16 contains metalloids and nonmetals.

Explanation;

• Groups 13–16 of the periodic table contain one or more metalloids, in addition to metals, nonmetals, or both.
• Unlike other groups of the periodic table, which contain elements in one class, groups 13–16 referred to as mixed groups contain elements in at least two different classes. In addition to metalloids, they also contain metals, nonmetals, or both.
• Group 14 also known as the carbon group contains carbon which is a non metal, silicon and germanium which are metalloids and tin and lead which are metals.
• Group 15 also known as the Nitrogen group contains non metals such as oxygen, metalloid tellurium and a metal polonium.
