Question

Electronic confregation

Answer 1

ANSWER

The electronic configuration of an atom in the shell atomic model may be expressed by indicating the number of electrons in each shell beginning with the first.

For example= sodium (11)

hope it helps you

Answer 2

HEYA.. ^^

In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals.

For example, the electron configuration of the neon atom is 1s2 2s2 2p6, using the notation explained below.
