The electron configuration of an atom refers to the manner in which its electrons are arranged in the atom's orbital shells and sublevels, or subshells. The orbital configuration of an atom's electrons is a primary facto... More »

The electron configuration for sulfur is 1s2 2s2 2p6 3s2 3p4. Sulfur's atomic number is 16; therefore, it has 16 electrons in its outermost energy level. Sulfur needs another two electrons to have a stable arrangement. More »

The valence electron configuration of Pb is [Xe] 4f14 5d10 6s2 6p2, or 2, 8, 18, 32, 18, 4 electrons per shell. It has four valence electrons in the outermost shell. Lead is placed in group 14 or p-block and Period 6 of ... More »

To make an electron configuration list, first find the atomic number, then count up the number of electrons and list them in the appropriate energy level and orbital. The information to write an electron configuration is... More »

The atomic radius of an atom is determined by the total number of electrons, electron shells and protons in an atom. Protons are located in the nucleus of an atom and create an effective nuclear charge. Electrons within ... More »

Chlorine has three filled or partially-filled electron orbital shells. Its electron configuration is 1s2 2s2 2p6 3s2 3p5, meaning its first and second electron orbital shells are filled, and its third electron orbital sh... More »

Isoelectronic elements are elements that have the same electron configuration in the outermost valence shells. These elements can either be atoms or ions, and in the case of isoelectronic compounds, molecules. This simil... More »
