I am doing a science project and I was wondering how many prontons cobalt has, how many electrons cobalt has, and how many neutrions cobalt has. |

Hi, I'm learning about the periodic table and i have chosen the element cobalt and i wanted to know what family does it belong to. i know its classified as a metal bascially every site i went to it doesn't tell me what family it belongs to...so what is the family. Also i would like to know some interesting facts,common compounds, and its important uses. i thank you for taking the time to read my letter.
From,Adrian
