uriel's nerd self said that it was protons neutrons and elements
The Atomic Mass is equal to the number of protons and electrons that an element has.
The atomic mass of an element is equal to the number of protons.
The atomic mass of an element is equal to its molar mass in grams/mol.
Hydrogen
The element's average atomic mass.
This is sum of the atomic weights of elements contained in the formula.
The number of protons, electrons, and neutrons:P
no. of protons in its neucleus

The mass number of an isotope of an element is equal to its atomic mass number. However, the atomic weight of an element is a weighted average of the isotopes that occur in the element in nature. Because almost all elements have more than one naturally occurring isotope (if they have any), the atomic weights of most elements are not integers, as mass numbers always are.
1. The molecular mass of a compound is the sum oh the atomic weights of the elements contained in the molecule of this compound. 2. The atomic number of an element is the number of this element in the Periodic Table of Mendeleev; the atomic number is equal to number of protons and electrons.
atomic weight = mass of protons + mass of neutrons
