Almost 80% of the atmosphere is NITROGEN N2 and another almost 20% of the atmosphere is Oxygen O2 This leaves water vapor to be a very SMALL part of the atmosphere. Because water vapor is such a small part of the atmosphere it is CONSIDERED to be the solute not the solvent.

Q.1 Due to me properties of mezals & non-metal.​

Answer»

Explanation:

Metals                                                          Non metals

Good conductors of electricity               Poor conductors of electricity

Good conductors of heat                       Poor conductors of heat

High density                                               Low density

Malleable and ductile                                  Brittle

Some more properties of metals:

 Hardness: Most of the metals are HARD, except alkali metals, such as SODIUM, potassium, lithium, etc. are very soft metals. These can be cut by using a knife.

Strength: Most of the metals are strong and have high tensile strength. Because of this, big structures are made using metals, such as copper (Cu) and iron (Fe). (Except Sodium (Na) and potassium (K) which are soft metals).

State: Metals are solid at room temperature except for mercury (Hg).

Sound: Metals produce ringing sound, so, metals are called Sonorous. Sound of metals is also known as Metallic sound. This is the cause that metal wires are used in making musical instruments.

Conduction: Metals are a good conductor of heat and electricity. This is the cause that electric wires are made of metals like copper and aluminium.

Malleability: Metals are malleable. This means metals can be beaten into a thin sheet. Because of this property, iron is used in making big ships.

Ductility: Metals are ductile. This means metals can be drawn into thin WIRE. Because of this property, a wire is made of metals.

Melting and BOILING Point: Metals have generally high melting and boiling points. (Except sodium and potassium metals which have low melting and boiling point.)

Density: Most of the metals have a high density.

Colour: Most of the metals are grey in colour. But gold and copper are exceptions.  

Some more properties of non metals :

 Hardness: Non-metals are not hard rather they are generally soft. But the diamond is an exception; it is the hardest naturally occurring substance.

State: Non-metals may be solid, liquid or gas.

Lustre: Non-metals have a dull appearance. Diamond and iodine are exceptions.

Sonority: Non-metals are not sonorous, i.e., they do not produce a typical sound on being hit.

Conduction: Non-metals are a bad conductor of heat and electricity. Graphite which is ALLOTROPE of carbon is a good conductor of electricity and is an exception.

Malleability and ductility: Non-metals are brittle.

Melting and boiling point: Non-metals have generally low melting and boiling points.

Density: Most of the non-metals have low density.

Colour: Non-metals are in many colours.
