what ion has 12 protons and 10 electrons?

so what would be the chemical symbol

oh i get it, the element symbol, then the ion?

Obvioulsly, it is a + 2 ion, now what has atomic NUMBER 12?

wow that just made sence. the actual question confused me. thanks

Look at the periodic table: what has atomic number 12.

then write it as this Ra+2
IT IS NOT Radium, you look it up.

To determine the ion with 12 protons and 10 electrons, we need to know its charge. The charge of an ion can be determined by comparing the number of protons (positive charge) and electrons (negative charge).

Since protons have a positive charge and electrons have a negative charge, the overall charge of an ion is determined by the difference between the number of protons and electrons. If the number of protons is greater than the number of electrons, the ion will have a positive charge. If the number of electrons is greater, the ion will have a negative charge.

In this case, if an ion has 12 protons and 10 electrons, there are 2 more protons than electrons. Therefore, the ion will have a positive charge since the positive charge exceeds the negative charge.

To determine the charge, we need to know the atomic symbol (or name) of the element that this ion represents. Each element has a unique number of protons, so knowing the element will allow us to identify the ion.
