Question

Classify the following into metals, non-metals and metalloids. Germanium, boron, carbon, iodine, copper, helium List three differences between metals and non-metals.

Answer 1

Answer:

metals- copper

non- metals- helium, carbon, iodine, boron

metalloid-Germanium

Difference between metal and non- metal

Metals

1. Metals are hard, lustrous, malleable, ductile and sonorous.
2. metals are good conductor of electricity.
3. examples- gold, iron, copper, etc.

Non-metals

1. Non-metals are soft, lack lustre, non-melleable, non- ductile, and non- sonorous.
2. non-metals are poor conductor of heat and electricity.
3. examples- graphite,carbon, helium ,etc.

Answer 2

Answer:

Metals:- Copper

Non metals:- Boron, Carbon, Iodine, Helium

Metalloids:- germanium

Explanation:

Difference between metals and nonmetals

Metals

1. Metals are generally shiny
2. metals are sonorous, malleable and ductile
3. Metals are the elements that are generally hard as strong metallic bond exists between the atoms
4. The elements contains 1,2 or 3 electrons in the valence shell.
5. Good conductors of electricity and heat.

Non metals

1. Non metals are usually dull.
2. They are not sonorous, ductile or malleable.
3. These are elements that are usually soft.
4. Elements contain 4,5,6 or 7 electrons in the valance shell.
5. bad conductors of heat and electricity.
