WebAn atom is a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.The atom is the basic particle of the chemical elements, and the … Webelectron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 11,836the mass of a proton. An electron is therefore considered nearly massless in comparison with a proton …

WebSep 5, 2016 · Each orbital can hold a maximum of 2 electrons; one will have +1/2 spin and the other -1/2 spin. So your question about the 4d orbitals. There are 5 4d orbitals, each may have 2 electrons, so if the 4d orbitals are completely filled you may have as many as 10 electrons. Since one of those electrons in each "box" is +1/2 and the other is -1/2 ...
