WebAtoms are unstable unless they have 8 valence electrons. Thus, only the noble gasses are “born” to be stable. All other atoms must gain, lose, or share electrons to be more like a noble gas. Stable atoms tend to have 8 valence electrons, like the noble gasses.

WebChlorine, with seven valence electrons, can gain one electron to attain the configuration of argon. When two different elements have the same electron configuration, they are called isoelectronic. Diamagnetism and Paramagnetism The electron configuration of an atom also has consequences on its behavior in relation to magnetic fields. 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 high res maps
