The atomic mass of Nitrogen is 14.0067the atomic mass of nitrogen is 14.007, so if you round off you will get 14
the atomic number is 53 and the atomic mass is 126.9 so you would round it up to 127
The average atomic mass number of Krypton is approximately 83.8 atomic mass units.
The atomic mass unit is used to express the measure of the atomic mass.

Example: Helium: Atomic Number; 2. Atomic Mass; 4.00 The electrons are the amount of protons in the nucleus. To find the protons you subtract the atomic number by the atomic mass. If the atomic mass consists of multiple numbers, round it up to the nearest whole.
The number of neutrons in an atom is easily calculated by taking the mass number and subtracting the atomic number. Take for example, Uranium: the mass number on the periodic table is 238, while the atomic number is 92. Take the difference of 238 and 92 and that will be equal to the number of neutrons. 238-92=146
I don't have a periodic table, but round its atomic mass to a whole number and subtract the amount of protons which equal the atomic number. So if the atomic mass is 24 and the atomic number is 12, 24-12=12.- example
Take the Atomic Mass and round it to the nearest whole number. Then subtract this number and the atomic number of that element.
the Atomic Mass is how much an element weighs
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
The atomic mass unit is used to express the measure of the atomic mass.
