The electron configuration for strontium is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s2, according to the Jefferson Lab website. The noble gas configuration of this element is [Kr] 5s2, with [Kr] representing the electron configuration of krypton.Know More
Strontium has an atomic number of 38, which means it has 38 protons. In a neutral atom, an equal number of protons and electrons cancel each other out, resulting in a net charge of zero. As a result, one neutral atom of strontium must have 38 electrons.
These electrons are arranged in energy levels around the nucleus. This element's electron configuration gives students an easy way to determine how the electrons in a strontium atom are arranged. There are two in the first energy level, eight in the second energy level, 18 in the third energy level, eight in the fourth energy level and two in the fifth energy level.Learn more about Atoms & Molecules
