Question

the outer electronic configuration of radio active atom ​

Answer 1

The arrangement of electrons in a molecule, atom or any other physical structure in molecular physics and magnitude chemistry is called electron configuration.

In electron configuration an electron is given a way to distribute it in an atom or molecular system.

For example, the electronic configuration of nion is 1s2 2s2 2p6.

Answer 2

Answer:

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 .

This electron must go into the lowest-energy subshell available, the 3s orbital, giving a 1s22s22p63s1 configuration. The electrons occupying the outermost shell orbital(s) (highest value of n) are called valence electrons, and those occupying the inner shell orbitals are called core electrons
