There are 3 protons and 2 electrons present in a lithium ion.
Lithium have available for bonding one electron.
Protons: 73 Neutrons: 108 Electrons: 73
li has atomic no. 3 so it has protons= 3 electrons- 3

There are 3 protons and 2 electrons present in a lithium ion.
Li+ ion has only 2 electrons in its only shell and they could be considered as both core and valence electrons.
Tantalum has 73 protons and electrons and its isotopes have 108 or 107 neutrons.
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.
You will have 8 valence electrons around Cl (it usually has 7 but gained one from Li). There are no valence electrons to show around Li because it gave it's valence electron to Cl. Answered by a chemistry teacher.
