The group number and period of the chromium in the periodic table are, respectively:(A) 6 and 3(B) 5 and 3(C) 6 and 4(D) 5 and 4
To determine the group number and period of chromium (Cr) in the periodic table, let's first locate chromium.
Finding Chromium in the Periodic Table:
Chromium has the atomic number 24.
It is located in period 4 (the rows of the periodic table are numbered from top to bottom).
Group Number:

Group numbers are typically numbered from 1 to 18 in the modern IUPAC system.
Conclusion:
Period of Chromium: 4
Group Number of Chromium: 6
Thus, the correct answer is (C) 6 and 4.
