An ion from a given element has 27 protons and 24 electrons. what is the charge on the ion? -

A neutral atom has equal number of protons and electrons. The proton is positive while the electron is negative so it cancels out when it has equal number. In this case, there are 3 more protons. Therefore the charge of the ion is 3+.

3+

1.solid

2.carbon dioxide

3.helium

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
