Electrons on shells
WebAn electron shell, or main energy level, is the part of an atom where electrons are found orbiting the atom's nucleus.. In chemistry and atomic physics, an electron shell may be thought of as an orbit followed by electrons around an atom's nucleus.All atoms have one or more electron shell(s), all of which have varying numbers of electrons. Each … WebThe second shell (2s and 2p) has a total of 8 electrons. And, the third (last) shell has 1 electron. The first and second shells comprise the core (inner) electrons = 2 + 8 = 10 electrons. The outermost (valence) has 1 electron. The shell diagram of the Na atom is shown here. The shell nearest the nucleus (first shell) has 2 electrons, the ...
