An element that has the outer electron configuration 5s²4d⁵ belongs to which period and group? A) period 4; group 8 B) period 5; group 9 C) period 5; group 7 D) period 5; group 3 E) period 5; group 13

Question

Quizplus · Accepted Answer

The outer electron configuration indicates that the element has 5 electron shells (period 5) and its valence electrons are located in the 5s and 5p subshells. The number of valence electrons in the 5th shell is 5 (1 from 5s, 4 from 5p), which corresponds to group 7.
