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.
Lithium is element #3, and it 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.
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.
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.
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.
