The nearest Whole number of atomic mass of potassium is 69
The atomic number refers to the number of protons in the atom. Since the proton cannot be an in-between number, the atomic number will have to be a whole number. On the other hand, the atomic mass does not have to be a whole number because it is the mass of an atom and is roughly equivalent to the number of protons plus the average number of neutrons in that particular element.
Few elements have isotopes. their atomic mass is not a whole number.
Elements exist as isotopes in nature. So their atomic weight is not a whole number.
Bexause its similar with the atomic mass
It is not usually a whole number. It would appear that you have been misinformed.
No, but a perfect square is usually the square of a whole number.
The atomic number is the whole number indicating the number of protons. It is usually directly above or below the element symbol.
Atomic mass of isotopes is not a whole number.
No. Atomic number is always a whole number. This would be the atomic mass.
6. An atomic number is always a whole number, so it does not need rounding.

No element has this atomic number. All atomic numbers are whole numbers.
A perfect square is a whole number that can be named as a product of a number with itself.
Usually they are measuring just the necleus of the atom since it would be a whole number. This is called finding the Mass number. The atomic weight is the whole atom together, which is a whole lot of decimals. So they take the atomic weight and round it to a whole number for the mass number. For example, Boron (an element on the table) has an atomic weight of 10.811. But scientists round the number upward to 11 to be the Mass number.
