what are the major difference between metals and non-metals
Answers
METALS
- METALS ARE SONOROUS
- METALS CONDUCT ELETRICITY WELL
- METALS ARE DUCTILE
NON METALS
- Non metals does not conduct electricity
- Metals are non sonorous
- .etals are non ductile
Answer:
Metals : 1) Metals can lose electrons easily.
2) Metals are solids at room ( Exceptions – Hg, Ga ).
3) Metals generally form ionic compounds.
4) Metals have low ionization enthalpies.
5) Metals are less electronegative. They are rather electropositive elements.
6) Metals have a high reducing power.
7) Metals have luster. They reflect light from polished or freshly cut surface.
8) Metals generally have high density.
9) They are good conductors of heat and and electricity.
10) Metals are malleable and ductile. They can be beaten into sheets and drawn into wires.
11) They have a three dimensional crystal structure with metallic bonds.
12) Metals usually have high tensile Strength.
13) Metals generally have 1 to 3 electrons in outermost shell of their atoms.
14) They generally form basic oxides.
15) They act as reducing agents.
Non metal: 1)Non-metals cannot lose electrons easily.
2) temperature Non – metals may be solids, liquids or gases at room temperature.
3) Non–metals generally form covalent compounds.
4) Non–metals have high ionization enthalpies.
5) Non–metals are electronegative.
6) Non–metals have a low reducing power.
7) Non-metals do not have luster.( Exceptions – Diamond and Iodine ).
8) Non-metals generally have low density.
9) They are usually bad conductors of heat electricity. (exception – carbon in the form of gas carbon and graphite ).
10) Non-metals are not malleable and ductile They are brittle when solid.They can be crushed into powder.
11) They have different types of structures with covalent and van-der-Walls’ bonds.
12) Non- metals usually have low tensile strength.
13) Non-metals generally have 4 to 8 in their outermost shell of the atom.
14) They generally form acidic oxides.
15) They act as oxidizing agents.
