There are many different types of ions, having many different quantities of electrons and protons. The H+ ion has one proton and no electrons. That's the simplest.
47 protons and 46 electrons.
35 protons, 36 electrons
An oxide ion has 8 protons. This is because it is an oxygen atom that has gained 2 electrons to become negatively charged. The number of protons remains the same as the number of protons in a neutral oxygen atom.
chlorine ion has 17 protons and 18 electrons.
A neutral atom has an equal number of protons and electrons. Protons are positively charged, and electrons are negatively charged. Therefore if you have an ion with a -1 charge, it has one extra electron. So your ion has 85 protons.
Beryllium (Be) has 4 protons and 4 electrons in its neutral state. When it forms the Be2+ ion, it loses two electrons, leaving it with 4 protons and 2 electrons. The Be2+ ion has a 2+ charge because it has lost two negatively charged electrons.
The iodide ion (I-) has 53 protons (p+) and 54 electrons (e-).
If you are not an ion then you will have 17.

A neutral atom has an equal number of protons and electrons. Protons are positively charged, and electrons are negatively charged. Therefore if you have an ion with a -1 charge, it has one extra electron. So your ion has 85 protons.
16 protons and 18 electrons
9 protons
