What is an electronic configuration?

Electronic configuration refers to the arrangement of electrons in an atom

Electrons are tiny negatively charged particles that orbit the positively charged nucleus of an atom

The electron configuration of an atom determines its chemical and physical properties, such as its reactivity, conductivity, and melting point. 

The arrangement of electrons in an atom is determined by its energy levels (which are also called shells), and the specific subshells within those shells. 

Electron configuration is typically represented using a notation that indicates the number of electrons in each shell and subshell, and it follows certain rules based on the principles of quantum mechanics.

What are Shells (n) and Subshells (s, p, d, f)?

Shell: The shell is the orbit in which the electrons revolve around the nucleus of an atom.

Each shell is assigned a number (n), starting from one for the first shell and increasing with each additional shell. 

The first shell can only hold a maximum of 2 electrons, while the second shell can hold up to 8 electrons, and subsequent shells can hold even more.

Subshell (or Orbitals): Within each shell, there are different subshells, which are labeled using letters such as s, p, d, and f. 

The s subshell can hold a maximum of 2 electrons, the p subshell can hold up to 6 electrons, the d subshell can hold up to 10 electrons, and the f subshell can hold up to 14 electrons. [1]

The shells and subshells of an atom determine its electron configuration, which in turn determines its chemical and physical properties.
