Answer:
1+
Explanation:
the number of protons tells you which element it is in the periodic table, you can notice that there is 1 less electron that then there is protons which means that the element had to give 1 electron away. When you get rid of 1 e- you have 1 proton more that electrons so that's why it's 1+
also the element is Cr
If it gains an electron it will be negatively charged and if it loses an electron it will be positively charged
Non-metal elements are Noble gases,Halogens,nonmetals,semimetals(metalloids). ( and maybe other metals)
