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 (orbits) around the nucleus.

What is the mass number of an atom?

Back

The mass number is the total number of protons and neutrons in the nucleus of an atom.

Front

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.

What is the difference between mass number and atomic mass?

Back

Mass number is a whole number representing the total number of protons and neutrons, while atomic mass is the weighted average mass of an element's isotopes.

Front

What is an isotope?

Back

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons.
