Question

difference between metal and nonmetal on the basis of their chemical property

Answer 1

Metals


1. Metals are electropositive.

2. They react with oxygen to form basic oxides.

4Na+O2 ----->2Na2O

3. These have ionic bonds.


Nonmetal


1. Non-metals are electronegative.

2. They react with oxygen to form acidic or neutral oxides.

C+O2----->CO2

3. These have covalent bonds.

Answer 2

Metals

# metals are electropositive

# they have ionic bonds

# they react as a reducing agent

# they loose electrons

# react with water to form oxides and hydroxides

Non-Metals

# non metals are electronegative

# they have covalent bonds

# they react as a oxidising agent

# they gain electrons

# do not react with water
