Is a ion a type of lithium?

No an ion is not a type of Lithium. An ion is an atom or molecule where the total number of electrons is not equal to the total number of protons, giving it a positive or negative electrical charge. This does mean that you can have an ion OF Lithium which is positively or negatively charged.


How many atoms of Lithium and Fluorine are needed to create the total charge of zero?

A Lithium ion has a charge of 1+ and a Fluoride ion has a charge of 1-, so Lithium and Fluorine pair in a 1:1 ratio.


What is the difference in the number of protons and electrons in an atom?

The number of protons (each has charge = +1) in an atom identify the element, e.g. hydrogen (1 proton), helium (2 protons), etc. If the number of electrons is the same, then the atom is neutral (total charge = 0). For example, a lithium atom has three protons in the nucleus (charge = +3) and three electrons (charges -1,-1,-1). The total charge is +3 -1 -1 -1 = 0. If the number of electrons is different than the number of protons, as when lithium would lose an electron, we say the lithium atom has been ionized--it is now a lithium ion and the charge is +3 -1 -1 = +1. If the lithium ion loses another electron, we would say it is doubly ionized or twice ionized and the charge would be +3 -1 = +2.


What is lithium plus nitrogen?

Li3N; the lithium ion has a charge of +1 (Li+) while the nitride ion has a charge of -3 (N3-)


How many protonsnutrons and electrons are in lithuim?

Lithium's atomic number is 3. Thus, it has 3 protons in each atom, all of which have a +1 charge. To be electrically neutral then, lithium must also have 3 electrons per atom.
