Lithium (Li).
Lithium has three protons and three electrons. The number of electrons always equals the number of protons. Lithium has two isotopes, one with three neutrons and one with four neutrons.
Lithium has three protons because elements always have the same number of protons.

Lithium
Protons, neutrons and electrons; protons and neutrons are composed from quarks and gluons.
Protons, neutrons, and electrons are the three main particles found in a neutral atom. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge.
The three particles that make up atoms are protons, neutrons, and electrons.
The three main parts of an atom are protons, neutrons, and electrons. Protons and neutrons are located in the nucleus, while electrons orbit around the nucleus in energy levels.

Protons, electrons, and neutrons are the three main parts of atoms. In an atom, the nucleus contains the protons and neutrons, the electrons are found in shells around the nucleus. On the periodic table, the atomic number tells you the number of protons of an element.
Protons, Neutrons and Electrons. Protons and Neutrons form the nucleas, surrounded by a cloud of Electrons.
Based on the atomic number of lithium there are three protons in a lithium atom.
