Argon is a non metal element. Mass number of it is 40.
No, it cannot. A whole number is a quantity without units - a pure number. A mass of 1 pound is a whole number of pounds but it is 0.45359 kilograms: not a whole number, or 453.59 grams, again not a whole number.
Approximately, yes. But the mass number is an average of the masses of the isotopes of the element, weighted together according to their abundance. This averaging of different whole numbers results in the mass number not being a whole number.

Boron - B - Group IIIThe atomic number is 5.The mass number is 11.
It is 4.0026 : the atomic mass can be a fraction.
The answer is simple it's one/1
The nearest Whole number of atomic mass of potassium is 69
Yes, the atomic mass on the periodic table is usually rounded to the nearest whole number, so an atomic mass of 30.97 would be rounded to 31.
Neon's atomic weight, rounded to the nearest whole number, is 20.
The atomic weight of zinc to the nearest whole number is 65.
You can determine the number of neutrons in an atom by subtracting the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number). This will give you the number of neutrons in the atom.
Sulfur- Element Number 16 on the Periodic Table of Elements
The mass number of an element is equal to the total number of protons and neutrons in its nucleus. It is rounded to the nearest whole number on the periodic table.
The mass number of an element is equal to the total number of protons and neutrons in the nucleus of an atom of that element.
Sometimes the atomic mass is listed as the average mass of the isotopes and contains a decimal. But since you can't have a fractional part of a proton or a neutron without creating a big mess, it is necessary to round to the nearest whole number. Subtracting the atomic number from the rounded atomic mass will give you the number of neutrons.
