Question

Write 10-10 chemical and physical property of metals and non - metals? ​

Answer 1

Physical Properties of Metals

1. State (solid at room temperature)

2. Luster

3. Malleability

4. Ductility

5. Hardness

6. Valency

7. Conduction

8. Density

9. Melting and Boiling Points are high

Chemical Properties of Metals

Electro-positive Character:

Metals tend to have low ionization energies, and typically lose electrons (i.e. are oxidized) when they undergo chemical reactions They normally do not accept electrons.

Physical Properties of Nonmetals

1. Physical State: Most of the non-metals exist in two of the three states of matter at room temperature: gases (oxygen) and solids (carbon). Only bromine exists as a liquid at room temperature.

2. Non-Malleable and Non-Ductile

3. Poor Conductor

4. No Luster

5. Melting and Boiling Points

6. Seven non-metals exist under standard conditions as diatomic molecules:  H2(g) ,  N2(g) ,  O2(g) ,  F2(g) ,  Cl2(g) ,  Br2(l) ,  I2(s) .

Chemical Properties of Nonmetals

Non-metals have a tendency to gain or share electrons with other atoms. They are electro-negative in character. Nonmetals, when reacting with metals, tend to gain electrons (typically attaining noble gas electron configuration) and become anions.
