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
In its shortest form, the electron configuration of Lawrencium is [Rn] 5f14 6d1 7s2. Simplifying any electron configuration requires the knowledge of how an atom's orbital sets are determined.Full Answer >
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.Full Answer >
The electron configuration for boron is 1s2 2s2 2p1. In the electron configuration, the first number stands for the energy level, and the letter stands for the orbital type, also called the sublevel of the main energy level. The second number, typically written in superscript, indicates the number of electrons.Full Answer >
