Maximum of 8 electrons in second energy level.
The second energy level of atoms can hold a maximum of 8 electrons.
Calcium atoms have 8 electrons in the second energy level. However, they are not the valence electrons. The outermost electrons in a calcium atom in the ground state are 2 4s electrons. So calcium atoms in the ground state have 2 valence electrons in the fourth energy level.
8
Carbon. Carbon is in the second period, so it has electrons in its second energy level, and it is in the fourth group in the second energy level, so it has 4 electrons.
8 electrons
if you're talking about atoms, 8 electrons can sit in the second energy level. two sit in the 2s orbital and 6 in the 2p orbital.
An atom with seven electrons will have five electrons in the second energy level.
2s^2 2p^6 8 electrons total
More energy have the electrons in the second level of energy.
Atoms can fill their outermost energy level by either gaining electrons from other atoms or by sharing the outermost electrons with another atom.
In the second energy level, eight electrons are allowed at most.
A boron atom has three electrons in its second energy level.
