There are 3 protons and 2 electrons present in a lithium ion.
In Li plus 1, the element is lithium (Li) which has 3 protons. Since it has a +1 charge, it means it has lost one electron, so it has 2 electrons.
Lithium-7 has 3 electrons.
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.

Lithium (Li) has an atomic number of 3, meaning it has 3 electrons. When an atom loses electrons, it forms a positive ion, so for Li to become a Li+ ion, it must lose 1 electron, leaving it with 2 electrons.

li has atomic no. 3 so it has protons= 3 electrons- 3
Lithium-7 has 3 electrons.
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.
Lithium is element #3, and it has 3 electrons.
This alkali metal is lithium (Li).

Li+ ion has only 2 electrons in its only shell and they could be considered as both core and valence electrons.
A lithium ion (Li+) has one less electron than a neutral lithium atom. This means a lithium ion has 3 electrons.
The configuration of the lithium ion (Li⁺) is 1s². In its neutral state, lithium has the electron configuration of 1s² 2s¹, but when it loses one electron to become Li⁺, it loses the 2s electron, leaving only the 1s electrons.
