Neutral Chromium (Cr I) is an important element in many laboratory plasma applications. In this work, expectation values of the radius for Cr I are calculated. These atomic data are calculated with three different atomic codes: Cowan code using the Hartree–Fock Relativistic approximation, SUPERSTRUCTURE and AUTOSTRUCTURE codes using scaled Thomas–Fermi–Dirac–Amaldi potential. Relativistic corrections are introduced according to the Breit–Pauli approach. The
configurations are included to obtain the expectation values of radius of Cr I and compared with available data. The novelty of our work is to obtain new values of
for the configuration of
and the values of
for all orbitals configurations considered in this work.
