which element has atoms with valence electrons in a higher energy level than those of calcium (ca)? (1 point) \ncesium (cs) \noxygen (o) \nbromine (br) \nlithium (li)

Answer

Brief Explanations:

Calcium is in the fourth - period. Valence electrons of elements in higher periods have higher energy levels. Cesium is in the sixth - period, while lithium is in the second, bromine in the fourth, and oxygen in the second. So cesium's valence electrons are in a higher energy level than calcium's.

Answer:

Cesium (Cs)
