Atomic structure

The atomic mass is the weighted average mass of an element's isotopes, measured in atomic mass units (amu).

Protons and Neutrons.

Positive charge.

Neutral (no charge).

Negative charge.

Number of Neutrons = Atomic Mass - Atomic Number.

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

It helps in determining the amount of substance in a given mass and is crucial for stoichiometry in chemical reactions.

Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons.

The atomic mass of an element is the average of the masses of its isotopes, weighted by their natural abundance.
