Review the electron configurations of the elements in group 2, moving down from beryllium (Be) to radium (Ra). What do you observe?
Select the correct answer.
O Moving down the group, each element has one more electron in its highest s sublevel than the element above it.
Each element's electron configuration has a noble gas core with two electrons in the next s sublevel.
Moving down the group, each element has two more electrons than the element that comes above it.
