Lithium is element #3, and it has 3 electrons.
li has atomic no. 3 so it has protons= 3 electrons- 3
Lithium-7 has 3 electrons.
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.
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.
The decrease in radius from Li to Li and then to Li₂ can be attributed to the increasing effective nuclear charge experienced by the electrons. In lithium (Li), the single electron in the outer shell experiences minimal shielding from the inner electrons, leading to a larger atomic radius. However, when lithium forms Li₂, the two lithium atoms share electrons in a covalent bond, resulting in a stronger attraction between the nuclei and the shared electrons, which pulls the electron cloud closer and decreases the overall radius.
Lithium hydroxide has three atoms in it, one each of lithium, hydrogen, and oxygen. Also note that lithium is Li, not LI. Little details matter to chemists. A capital I means iodine.
