Atomic weight is sum of the number of protons and neutrons in the nucleus of an atom. Protons and neutrons, as members of the nucleus, are sometimes called nucleons. The atomic weight is sometimes said to be the nucleon number.
The relative atomic mass (Ar) (also known as atomic weight and average atomic mass) is the average of the atomic masses of all the chemical element's isotopes as found in a particular environment, weighted by isotopic abundance. This is frequently used as a synonym for the standard atomic weightand it is not incorrect to do so since the standard atomic weights are relative atomic masses, although it is less specific to do so. Relative Atomic Mass also refers to non-terrestrial environments and highly specific terrestrial environments that deviate from the average or have different certainties (number of significant figures) than the standard atomic weights.

The atomic weight basically means the weight of the element. For example, if I'm 97 lbs, that is my weight. Another example would be the atomic weight of carbon is 12.011 because that is how much the carbon weighs.
Atomic weight = number of protons + number of neutrons :)
It is the weighted average of the masses of naturally-occurring isotopes.

atomic mass is the atom that can carry the number of neutron on the shell,where as atomic weight the weight of mass.
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
Helium atom has 2 protons and 2 neutrons (that accounts for its atomic weight). The atomic weight of helium is 4.00260
Yes; helium has an atomic weight of 4.00260, and lead has an atomic weight of 207.2.

You subtract the atomic number from the atomic weight. For example, if you have a helium atom and its atomic weight is 4 and you subtract its atomic number (2) the number of neutrons in the helium atom is 2.

Florine has a greater Atomic Weight because Carbon has a Atomic Weight of 12 amu (atomic mass units) while Florine has a Atomic Weight of 19.
