Curium is a transuranic radioactive chemical element with atomic number 96. Let us discuss electron configuration of Curium.

Electronic configuration of curium atom is 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶ 4f¹⁴ 5d¹⁰ 6s² 6p⁶ 5f⁷ 6d¹ 7s² Curium is a f block element and actinoid series in the periodic table. symbol is “Cm” and shell structure is 2, 8, 18, 32,25,9, 2. Curium is a silvery metal with high melting and boiling point.

We will discuss some interesting facts about Curium electron configuration, configuration notation, diagrams, ground state and excited state electron configuration.

How to write curium electron configuration

Electronic configuration of Cm is [Rn]5f⁷ 6d¹ 7s² and the 7 ^th period element in the periodic table. Distribution of electrons around the nucleus of an atom obeying three set of rules that listed below,

• Arrangement of an electrons in an orbital by increasing order of energy according to the Aufbau principle the order of electrons fill orbitals looks like1s,2s,2p,3s,3p,4s,3d,4p,5s,4d,5p,6s,4f,5d,6p,7s

• Electrons in an orbit can hold maximum of two electron with opposite spin according to Pauli’s-Exclusion principle that is one orbit can hold 2maximum of 2 electrons with opposite spin.

• Electrons first filled all the orbit with similar energy and then they will pair that obey Hund’s rule

Curium electron configuration diagram

Curium electron configuration is [Rn] 5f⁷ 6d¹ 7s² where the distribution of electrons among the orbitals is as follows listed below,

• Each shell can hold a fixed number of electrons there for n^th shell can hold 2n² electrons.

• Filling of electrons in sub shells of lower energy level to higher energy level follow the n+l rule.

• Each shell is included of one or more subshells for example first K shell have 1 subshell, L shell have 2 subshells, M shell have 3 subshells, N shell have 4 subshells.
