Zink is a meta element. Atomic mass of it is 65. Atomic number of it is 30.
Nitrogen, element 7, has an atomic mass of 14.0067, rounded to 14.007.
Boron - B - Group IIIThe atomic number is 5.The mass number is 11.
The atomic mass of an element is the weighted average of masses of the isotopes of the element, weighted in proportion to their abundance.
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
atomic weights is usually the number that has decimal points. so whenever you see a number with decimal point on periodic table, then that is the atomic mass.
Aluminum's atomic mass is 26.9815386,but if rounded up,it is 27.
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.
Zink is a meta element. Atomic mass of it is 65. Atomic number of it is 30.
Krypton is a non meta element. Atomic mass of it is 84.
Argon is a non metal element. Atomic mass of it is 39.94.

The atomic mass of the most stable isotope of einsteinium is 252,083 (rounded).
Nitrogen, element 7, has an atomic mass of 14.0067, rounded to 14.007.
Atomic mass of isotopes is not a whole number.
It is 4.0026 : the atomic mass can be a fraction.
