Atomic mass by Ally

Atomic mass is the average mass of atoms of an element. This is calculated by using the abundance of isotopes in an elements. Technically, the mass would equal out to be the sum of the protons, neutrons, and electrons in the certain atom. In retaliation to that, the mass of all electrons just happens to be less than any other particle, so the mass ends up to be just the nucleus.







The Atomic mass can be found on the periodic table with its certain element. It is found normally at the bottom of the designated box right under its element’s symbol.

INTERESTING FACTS
1.    Atomic mass showed on the first ever periodic table in 1869.
2.    The atomic mass is quite close to the atomic number from the protons and neutrons of an element’s nucleus having the same mass.
3.    A Dalton is a single unit of atomic mass.




QUESTIONS
1.    Why is the atomic mass not a whole number?
2.    What’s the difference between atomic mass and average atomic mass?

3.    Is atomic mass effected by transmutation?
