WebFeb 20, 2014 · An s-orbital holds 2 electrons. Thus n=1 shell can hold two electrons. The n=2 (second) shell has: The 2s orbital The 2p orbitals s-orbitals can hold 2 electrons, the p-orbitals can hold 6 electrons. Thus, the second shell can have 8 electrons. The n=3 (third) shell has: The 3s orbital The 3p orbitals The 3d orbitals Weboctet rule: Atoms lose, gain, or share electrons in order to have a full valence shell of eight electrons. Hydrogen is an exception because it can hold a maximum of two electrons in its valence level. Free Radicals Some elements, most notably nitrogen, can form compounds that do not obey the octet rule. WebTherefore, the selenium atom will have two electrons in the first shell, eight in the 2nd orbit, eighteen electrons in the 3rd shell, and the remaining six electrons will be in the fourth shell.
