(c) They are hard.

(d) They are lusturous and shiny.

(e) They have high densities.

(f) They are good conductors of heat and electricity.

(g) They have high melting and boiling points.

Non-metals:

(a) They are non-sonorous.

(b) They are non-ductile.

(c) They are soft.

(d) They are non-lusturous.

Answer 2

Answer:

hello dear

here is the answer to your question:

Explanation:

lets first talk about METALS :

* they have 1,2,3 electrons in their valence shell.

* they loose electrons to form CATIONS that are positively charged ions.

* they are strong reducing agents.

* they are good conductors of electricity.

* they are highly reactive.

* they are metallic in nature and their metallic character increases down the group.

* they have have low ionisation energy.

for e.g - Sodium , potassium , magnesium etc.

NON-METALS:

* they have 5,6,7 electrons in their valence shell.

* they gain electrons to form ANIONS that are negatively charged ions.

* they are strong oxidising  agents.

* they are non- conductors of electricity.

* they are also highly reactive.

* they are non-metallic in nature.

* nature- electronegative non-metals

* they have have high ionisation energy.

for e.g - Iodine , Chlorine etc.

hope this helps you
