The electronic configuration of a ground-state Cr-atom :
1s²2s²2p⁶3s²3p⁶4s²3d⁴
<h3><u>What are electronic configurations?</u></h3>
The arrangement of an atom's or molecule's (or other physical structure's) electrons in their atomic or molecular orbitals is known as the electron configuration in atomic physics and quantum chemistry. For instance, the neon atom's electron configuration is 1s² 2s² 2p⁶, which means that 1, 2 and 6 electrons, respectively, are present in each of the 1s, 2s, and 2p subshells.
According to electronic configurations, each electron moves individually within an orbital while being surrounded by an average field produced by all other orbitals. Slater determinants or configuration state functions are used to mathematically characterize configurations.

Answer:
Two similar atoms or different atoms
Explanation:
A molecule is made up of at least two similar atoms or different atoms.
A molecule is the smallest particle of a substance capable of independent existence.
- Monoatomic molecule is made up of one atom
- Diatomic molecule is made up of two atoms bounded together.
- Polyatomic molecule are made up of more than two molecules bounded together.
