Question

Periodic table and electronic configuration question and answers

Answer 1

Answer:

The distribution of electrons in an atom is called as Electronic Configuration. Formula 2n2 helps in the determination of the maximum number of electrons present in an orbit, here n= orbit number. ... The different energy levels are known as 1, 2, 3, 4….. and the corresponding shells are known as K, L, M, N and so on.

Answer 2

Explanation:

A table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns is called periodic table.

The electronic configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals.
