Valence electrons are located in the outermost shell in an atom. Chromium has only one valence electron.
A chromium ion has the atomic number 24. This means that a neutral atom has 24 electrons. Because it has the net charge of positive three, it has 21 electrons.
The isotope Cr-54 has 24 electrons.
It varies across the group e.g. Sc = 3 Ti = 4 V = 5 Cr = 6 Mn = 7
24, considering that an electron has a negative charge and the number of protons (positivley charged) is 24, an atom has to be neutrally charged

The Lewis structure for Cr (chromium) has a total of 24 valence electrons. It will have 6 single bonds with other atoms to satisfy the octet rule, with the remaining 10 electrons as lone pairs on the central chromium atom to complete its octet.
Sulfur (S) is the representative element in period 4 with six valence electrons.
Chromium is in the d block. It contains 24 protons.
The isotope Cr-54 has 24 electrons.
A chromium atom loses three electrons to become a Cr3+ ion. The equation for this process is Cr → Cr3+ + 3e-.
It varies across the group e.g. Sc = 3 Ti = 4 V = 5 Cr = 6 Mn = 7

Cl-Cr-Cl
It has 4 d electrons.
