Helppppp:
A neutral atom of a carbon has six protons and six electrons. If a carbon atom gains one electron it will have six protons and seven electrons. Classify this carbon atom as a cation or an anion. Explain your reasoning .
It is an anion because anions are negatively charged atoms. A proton is positive and an electron is negative. If you have more electrons than protons, you are left with a negative charge.
