Question

1.) what is a Ore?
2.) Physical properties of metals?
3.) What is sulphur, nitrogen, silicon?
4.) what are non metals?

Answer 1

#1.) Ore is a naturally occurring solid material from which a metal or valuable mineral can be extracted profitably.

#2.) physical properties of metals are:-
a.)Lustrous
b.)High Density
c.)High Tensile Strength
d.) High Melting and Boiling Point
e.) Hard
f.) Good conductors of heat and electricity

#3.) Nitrogen and sulphur = Non Metal
Silicon = Metalloid

#4.) An element or substance which do not exhibit Metallic property ,and do not allow the flow of electrons and current carrier.

Answer 2

1:) ore is a naturally occurring solid material from which a metal or valuable mineral can be extracted
2:)physical properties of metals are
i:)lustrous
ii:)shiny
iii:)high tensile strength

3:) sulphur is a non metal
nitrogen is a non metal
silicon is neither metal or nonmetal it is a metalloid
4:)a non metal is a chemical element that mostly lacs metallic attributes physically nonmetals tend to have low melting and boiling points .
