how many unpaired electrons are present in chromium
Answers
Answer:
Six unpaired electrons
One unpaired electron. Electron configuration for chromium: [Ar] 4s1, 3d5. Six unpaired electrons.
Chromium has two unpaired electrons.
As per the question given,
The electron configuration of an element refers to the arrangement of electrons in the energy levels (or orbitals) around the nucleus of an atom. It gives information about the number of electrons in each orbital and their spin. The electron configuration of an element can be used to predict its chemical properties and reactivity.
The electron configuration of elements can be determined using the periodic table and the rules for filling orbitals (Aufbau principle, Hund's rule, and Pauli exclusion principle). The electron configuration of elements can also be predicted using various models and computational methods.
Chromium has the electron configuration [Ar] 3d5 4s1. There are five electrons in the 3d orbital, and one electron in the 4s orbital. Out of these six electrons, two are unpaired.
Therefore, chromium has two unpaired electrons.
