Answer 2

Explanation:

• For 1:

Metals are defined as the elements which loose electrons to attain stable electronic configuration. After loosing electrons, the metals usually form positive ions known as cations.

For the given options:

Option a: Calcium hydroxide

The chemical formula for the compound is $Ca(OH)_2$ and the metal present in this compound is Calcium.

Option b: Milk of magnesia

The chemical formula for the compound is $Mg(OH)_2$ and the metal present in this compound is Magnesium.

Option c: Sodium hydroxide

The chemical formula for the compound is NaOH and the metal present in this compound is sodium.

Option d: Copper hydroxide

The chemical formula for the compound is $Cu(OH)_2$ and the metal present in this compound is Copper.

• For 2:

Non-metals are defined as the elements which gain electrons to attain stable electronic configuration. After gaining electrons, the non-metals usually form negative ions known as anions.

For the given options:

Option a: Sulfuric acid

The chemical formula for the compound is $H_2SO_4$ and the non-metal present in this compound is Sulfur.

Option b: Nitric acid

The chemical formula for the compound is $HNO_3$ and the non-metal present in this compound is Nitrogen.

Option c: Hydrochloric acid

The chemical formula for the compound is HCl and the non-metal present in this compound is Chlorine.

Option d: Sulfurous acid

The chemical formula for the compound is $H_2SO_3$ and the non-metal present in this compound is Sulfur.
