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

The atomic number of chromium is 24

Electronic configuration – 1s22s22p63s23p64s23d5

Outermost orbit = 4s

The Period of the element = 4

Nearest noble gas = Ar(18)

Group of chromium = 24 – 18 = 6

Hence, group = 6

So, the correct option is (C)
