Question

total number of orbitals containing one or more electrons in the ground state of CR and Ni atoms are respectively a) 15 and 15 (b) 15 and 18 (c) 24 and 28 (d) 7 and 7​

Answer 1

Answer:

c

Explanation:

this confirm correct as i solved

Answer 2

Answer:

(b) 15 and 18

10 electrons

10 electronsThere can be two electrons in one orbital maximum. The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max.
