Helium (He) has 2 electrons in its outer shell. Calcium (Ca) has 2 electrons in its inner shell and 8 electrons in its outer shell.
2 outer shell electrons
Boron has 3 electrons in the outer shell and 2 electrons in the inner.
Magnesium has a total of 12 electrons. The electron configuration would be 1s2 2s2 2p6 3s2. Therefore, 2 electrons in it's outer shell.
The outer shell (N=4) of the copper element has 2 electrons.
The number of electrons in the outer shell of Beryllium is 2.
manganese have 2 electrons in their outer most shell
2 electrons
Two. An inner shell contains 2 electrons; and an outer shell contains 2 electrons on its near side and 4 more electrons on its outer side. Total of 8 electrons.
There are 2 electrons in valence shell of calcium. :-)
