First: Atomic Mass if the weighted average of the naturally occuring isotopes of an element. So the averge is un likely to be a whole number.
Second: Atomic mass of an isotope is NOT the sum of the protons and neutrons, thats the mass number. A proton's or a neutron's mass is not exactly 1. Electrons do have mass. So even though one isotope of oxygen has 8 protons and 8 neutrons, the atomic mass is not 16.
In a round-about way this is true. Neutrons and protons are made up of quarks. Protons have 2 up quarks and 1 down quark while neutrons have 1 up quark and 2 down quarks. The reason that the reported mass of an elements is not a whole number is largely because it is an average of he masses of all the isotopes of the element - weighted by the fraction of each isotope in nature. The differences in the weights of the isotopes is due to differences in the number of neutrons in the nucleus - and since neutrons are made up of quarks - yeah - the existence of quarks makes the existence of neutrons possible which makes different isotopes possible which makes it possible for an element to have an average atomic weight that is not a whole number.

Atoms of most elements are not able to exist independently. Atoms form molecules or ions aggregate in large numbers to form the matter that we can see. Molecule is capable of independent existence.
Because of the difference in mass number. Isotopes must have different numbers of neutrons.
Elements with atomic numbers 89-94: natural elements.Elements with atomic numbers 95-98: artificial elements but they are also discoverd in nature as ultratraces.Elements with atomic numbers 99-103: artificial elements.
It is possible only because of different number of neutrons.

Atomic numbers.
There is an infinite amount if numbers in existence.
because of its no. in table of elements
Because they have their own Numbers's own. Carbon and their own chemical.
Atoms of most elements are not able to exist independently. Atoms form molecules or ions aggregate in large numbers to form the matter that we can see. Molecule is capable of independent existence.
Because different elements have different numbers of protons, which determines the atomic number.
god (:
Because the masses of protons, neutrons and electrons are not whole numbers.

Hippasus, However Pythagoras could not accept the existence of irrational numbers, because he believed that all numbers had perfect values. But he could not disprove Hippasus' "irrational numbers" and so Hippasus was thrown overboard and drowned.
The number 1 came because it had 1 angle and so on with all the numbers up to 9
