Question

2)complete activity in metals and nonmetal

3) prepare and write physical and chemical properties of metals

4) prepare and write physical and chemical properties of nonmetals​

Answer 1

Answer:

aluminium ,iron ,gold ,silver , copper is metal

Answer 2

1 ans. Shiny, malleable, fusible and ductile. Non metals is a substance that do not exhibit properties of metals such as hardness, luster, malleability, ductility and ability to conduct electricity.

Example for metals: gold, silver, iron, copper, etc ............

Example for non metals: hydrogen, carbon, nitrogen, oxygen, etc ..............

2 ans. Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the the exception of mercury, which is liquid at room temperature ( Gallium is liquid on hot days )

3 ans. Nonmetals are poor conductors of heat and electricity............

Unlike metals, nonmetals are not malleable and ductile.

Usually, non metals react with other non metals in high temperature.

Non metals react more with metals than with non metals.

Most non metals do not react with air in room temperature.
