Question

difference between metal and non metal...pls ans​

Answer 1

Metals :

1. Metals have lustre and can be also be polished.
2. Metals are generally hard.
3. Metals are malleable and ductile.
4. Metals generally have high melting and boiling points.
5. Metals are good conductors of heat and electricity.
6. Metals are sonorous.
7. Metals generally have high density.
8. Metals generally have high tensile strength and hence can't be broken easily.
9. Metals are generally solid at room temperature.
10. Metals are electropositive elements and hence lose one or more electrons to form positive ions.
11. Metals form basic oxides.
12. Most of the metals displace hydrogen from water or steam.
13. Metals which fly above hydrogen in the activity series displace hydrogen from dilute acids.
14. Highly electropositive elements like potassium, sodium, calcium, etc. react with hydrogen to form ionic hydrides which are generally and unstable.
15. Metals generally combined with chlorine to form solid iron chloride which conduct electricity in the aqueous solution or in the molten state.
16. Metals have a strong tendency to lose electrons and hence they behave as reducing agents.

Non metals :

1. Except iodine, non metals do not have lustre and also can't be polished.
2. Non metals are generally soft.
3. Non metals are neither malleable nor ductile; they are brittle.
4. Non metals have low melting and boiling points.
5. Non metals except graphite and carbon are bad conductors of heat and electricity.
6. Non metals are non sonorous.
7. Non metals generally have low densities.
8. Non metals generally have low tensile strength and hands can be broken easily.
9. Non metals are either solids or gaseous at room temperature.
10. Non metals are electronegative elements and hence gain one or more electrons to form negative ions.
11. Non metals form either acidic or neutral oxides.
12. Non metals generally do not react with water or steam.
13. Non metals don't react with dilute acids and hence don't displace hydrogen form dilute acids.
14. Non metals form covalent hydrides which are quite stable.
15. Non metals combine with chlorine to form covalent chlorides. These are either gases or liquids. Since non metal chlorides don't contain iron ,therefore, they don't conduct electricity.
16. Non metals have a strong tendency to accept electrons and hence they behave as oxidizing agents.

Answer 2

Answer:

Metals have one to three electrons in their outer shell

non-metals have four to eight electrons.

Another difference is that metals tend to lose their valence electrons

non-metals share or gain valence electrons

While metals are good conductors of electricity and heat, non-metals are poor conductors.....

hope this answer help you dear....♥️
