# Argon Atom

In dating: Potassium–argon methods of mass 40 (40 K) to argon gas of mass 40 (40 Ar) formed the basis of the first widely used isotopic dating method.Since radiogenic argon-40 was first detected in 1938 by the American geophysicist Lyman T. Aldrich and A.O. Nier, the method has evolved into one of the most versatile. Group 18 elements (helium, neon, and argon are shown) have a full outer.

Bohr diagrams indicate how many electrons fill each principal shell.

### What is the electron configuration of argon?

The electronic configuration of Argon (atomic number is 18) is-

$1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{6}$

Note:-
For writing the electronic configuration of elements, the Aufbau Principle is used. In Aufbau Principle, the electrons are filled according to the increasing energy level of orbitals.

According to the Aufbau Principle, first the atomic number of element is determined (like here oxygen has atomic number 8) and then the electrons are filled in this order-
1s 2s 2p 3s 3p 4s 3d and so on..
.
In 's' orbital, maximum number of filling the electrons is 2.
In 'p' orbital, maximum number of filling the electrons is 6.
In 'd' orbital, maximum number of filling the electrons is 10.
In 'f' orbital, maximum number of filling the electrons is 14.

For example-
i) The electronic configuration of Chlorine (atomic number is 17) is-
$1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{5}$
ii) The electronic configuration of Titanium (atomic number is 22) is-

$1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{6} 4 {s}^{2} 3 {d}^{2}$

Color: Colorless.Bohr model is an early model of atomic structure in which electrons circulate around the nucleus in discrete stable orbits with different energy levels. This model was the first to predict and explain the atomic spectrum of the hydrogen atom, which arises as the electron jumps from one orbit to another orbit of lower energy, giving off.
