Lithium as number of protons is equal to the atomic number..
Lithium.
If you add 3 protons to lithium (which has 3 protons), you would create an element with 6 protons, which is carbon on the periodic table.
Lithium is element 3 on the periodic table and has 3 electrons and 3 protons
The element lithium has 3 protons and 3 electrons.
With 3 protons
No. Lithium is an element with atomic number 3 (or 3 protons) and neon is an element with atomic number 10 (or 10 protons). Both are not same.
Adding protons changes the element, creating a new element with a different atomic number. The element with 3 protons is not aluminum, so adding 3 protons would create a different element rather than a 3+ ion of aluminum.
Each element has a different number of protons and neutrons. So it changes for each element.
Seeing the number of protons, I would guess nitrogen.
Any particle with 24 protons, despite the number of neutrons or the charge, is chromium.
As you can see in any periodic table, Lithium is element #3; that means that each atom has 3 protons.
Protons are protons, no matter what element they are in.
