What is mass number of elements?
The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.

What is the mass number of an element?
mass number, in nuclear physics, the sum of the numbers of protons and neutrons present in the nucleus of an atom.
How do you find mass number?
Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
What is the protons number of krypton?

What is mass number?
Is mass number atomic mass?
Atomic mass is also known as atomic weight. Atomic mass is the weighted average mass of an atom of an element based on the relative natural abundance of that element’s isotopes. The mass number is a count of the total number of protons and neutrons in an atom’s nucleus.
Where is mass number?
An element’s mass number is unique to that element, and it’s listed right underneath the element’s symbol in the periodic table. The mass number of an element is not the same as its atomic number.
