What is a Bohr model?

Back

A Bohr model is a diagram that represents the structure of an atom, showing electrons in specific energy levels around a nucleus containing protons and neutrons.

What is the atomic number of an element?

Back

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