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

the protons is the number that is the atomic number.
= 3 protons
In Lithium, there are three protons and three neutrons. Protons= the atomic number Neutrons=Atomic mass-Atomic Number
There are 3 protons.
Lithium nucleus has 3 protons.
Lithium has the atomic number of 3, which means it has 3 protons, and a neutral atom of lithium has 3 electrons.
lithium has 3 protons flouride has 9 protons so total of 12 protons in LiF.

lithium has 3 protons which would also be 3 electrons.
Sodium nucleus has 11 protons.

Lithium has three protons in the nucleus
The atomic nucleus of lithium has 3 protons.
LI ; lithium is an example with 3 protons.
nucleus... if it is still "lithium". Otherwise, it is 3 protons and some neutrons, depending on the isotope of lithium.
Protons and Neutrons
Protons- 3Electrons- 3Neutrons- 4
The number of protons in the nucleus is what defines the element. If there are 3 protons, it must be lithium. If there are 6 protons, it has to be carbon. Etc.
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.
The atomic number of lithium (Li) is 3, and so it has 3 protons in the nucleus. The number of neutrons depends on which isotope of lithium you have. The most common isotope (92.5%) is 7Li with 4 neutrons.A neutral atom of lithium has three electrons in it. Lithium has two electron shells that have electrons in them. The 1s shell has a pair of electrons in it (the maximum), and the 2s shell has one electron in it. Note that this is a neutral atom of lithium, and lithium is reactive. It would like to loan that 2s electron out if it can. It will react with air, either with the oxygen in it or the moisture, if there is any.See the Related Questions below for more information about the particles in the nucleus.
Based on the atomic number of lithium there are three protons in a lithium atom.
