A student is given a sample of an unknown substance. He is asked to determine if it is classified as a metal, a metalloid, or a nonmetal. He discovered that the unknown element conducted some heat and electricity, had a shiny luster, and broke easily. This element is most likely a 

• metal
• nonmetal
• metalloid
• cannot be determined

What is the formula to solve for the neutron?
