Based on the atomic number of lithium there are three protons in a lithium atom.
Lithium has 3 protons. The atomic number and the number of protons will be the same.
Protons- 3Electrons- 3Neutrons- 4
Lithium with a mass number of 8 will have 3 protons. The mass number represents the total number of protons and neutrons in an atom's nucleus, and since lithium has an atomic number of 3, it means it has 3 protons.
There are 17 protons in the nucleus of an atom of chlorine.

An atom of osmium has 76 protons in its nucleus.
The atomic number of lithium is 3. Therefor there are 3 protons and neutron in the nucleus of lithium. Lithium also has 4 neutrons. atomic # = protons and neutrons neutrons = rounded atomic mass - atomic number Sources- 7th grade Acc. Science
Each barium atom has 56 protons in its nucleus.
The number of protons in the nucleus of an atom is equal to the atomic number of the element.
There are 24 Protons in Chromium's nucleus.
Lithium ions have three protons in their nucleus, as lithium's atomic number is 3. In terms of elections, a neutral lithium atom also has three electrons. However, when it is ionized to form a lithium ion (Li+), it loses one electron, resulting in two electrons. Thus, a lithium ion has three protons and two electrons.
