WebWhat are shells in an atom? Shell (electron): A grouping of electrons in an atom according to energy. The farther a shell is from the nucleus, the larger it is, the more electrons it can hold, and the higher the energies of those electrons. The first shell (closest to the nucleus) can hold two electrons. The second shell can hold 8 electrons. WebMagnesium is a chemical element with atomic number 12 which means there are 12 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. convert 90 kilos to lbs
