What is an alkaline earth metal that has 5 shells?

The alkaline earth metals consisted of 5 shells have been beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

The alkali earth metal has been the element of group 2. The elements have consisted of the 2 valence electrons.

The electrons in the elements have been assigned the electron address based on the capacity of the shells to occupy electrons.

The electrons have been filled based on the energy level of the shells.

The order of the increasing energy level has been:

1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s.

The elements with the occupied 4p shells will have the 5 shells.

The elements in group 2 consisted of 5 shells have been beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

The elements in the alkaline earth metals group; beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra), have two electrons in their outer electronic shell.

Explanation:

i would say b

explanation:

but i think i would need more information than that

the objects have the same charge is correct.
