There are 3 protons and 2 electrons present in a lithium ion.
Three protons and two electrons.
Lithium-7 has 3 electrons.
5
All lithium atoms and ions have three protons. The lithium ion has a charge of +1, meaning there is one less electron than protons, two.
They do not. Helium has two electrons in its valence shell. Neon has eight, plus two more beneath the valence shell. However, since the first energy level can only hold two electrons, helium has a full valence shell, which explains why its properties are similar to those of neon.
Three protons and two electrons.
li has atomic no. 3 so it has protons= 3 electrons- 3
Lithium-7 has 3 electrons.
3
Lithium is element #3, and it has 3 electrons.
This alkali metal is lithium (Li).
Li plus

Li+ ion has only 2 electrons in its only shell and they could be considered as both core and valence electrons.

When you say Ion you have to specify whether its negative or positive and the number associated with it. For example: if its Li 3- it means it has 3 more electrons then regular Lithium (which has 3 electrons) that makes it 6 electrons and 3 protons (this nr doesnt change) for Li 3-. Obviously calculations vary depending on the type of ion.
