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.
The electron configuration of radium does not follow the pattern of the other elements in group 2.
