plz explain me
scandium is a transition element, so its two outermost shells are incomplete. also, the atomic no. i.e. the no. of protons in scandium is 21 and lies in period 4 which means that it has 4 shells. That is why its e.c. is 2,8,9,2
notice that the two outermost shells are incomplete. Third shell can take 18 but has 9. Fourth shell can take 8 but only takes 2
tnx for help
