A lithium ion has three protons and 2 electrons - Li+. A neutral lithium atom has 3 electrons, but loses one to form an ionic bond with a non-metal.
3 protons and 2 electrons may correspond to the Li+ atom.
A Lithium Ion (Li2+)
A lithium 1 positive ion
a bromine ion will have 36 electrons and a -1 charge
positive!(: more protons = positive more electrons = negative say an atom has 2 more protons than electrons, it has a charge of 2+ if it had 3 more electrons than protons, it has a charge of 3- if electrons are taken away, what will the charge be? answer: positive, because there are less electrons same works vice versa. hope i helped! source: 8th grade science class(:
2 protons, 2 electrons, and 1 neutron
It is a neutral atom - beryllium. The protons and electrons balance each other exactly so there is no overall charge.
-4. There are four more electrons than protons, and the charge of each is precisely opposite.
There are more protons than electrons, and since protons are positive, the ion will be positive. Because there are two more protons, the charge is +2.
a bromine ion will have 36 electrons and a -1 charge
Electrons have a -1 charge while protons have a +1 charge. Thus, subtracting the number of electrons from the number of protons gives the charge of a species. For example, if a lithium ion has 3 protons and 2 electrons, it has a +1 charge.

It has 3 more protons than electrons. Protons are 1+ and electrons are 1-. So the charge on the hypothetical ion would be 3+
The Electrons and the Protons.
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.
It is a neutral atom - beryllium. The protons and electrons balance each other exactly so there is no overall charge.
Li+Basic information: Protons are positively charged and electrons are negatively charged. The charge of one proton cancels out the charge of one electron. The atomic number represents how many protons are in the nucleus of an atom.If the ion has more protons than electrons, then it will be positively charged overall. If the particle has three protons, then the atomic number is three, and the element is Lithium.
