How many protons in rhenium
Did you know?
WebAtoms are grouped according to the number of protons and neutrons in the atomic nucleus. The number of protons in an atom determines the chemical element of the atom, and the number of neutrons determines isotope of that element. A stable atom is an atom in which all of its orbitals are occupied by electrons so that none of the orbitals are vacant. http://clas.sa.ucsb.edu/staff/terri/Ch%202-chapter%20test.pdf
