8 electrons. Can be found from the formula 2n2. Where n=the number of the energy level. The number of electrons in the second shell is very important to remember however, because it provides for the octet rule of bonding that almost all elements conform to. Elements wish to have 8 electrons in their outer shell, making the Noble Gases unreactive, and providing for the charges, or oxidation states, of all elements that determine how they bond. Davey.

8 electrons
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.
Atoms don't do anything. If the electrons go to a higher energy state, they use energy. If they fall back to a lower state, they release energy. This shouldn't affect the entire atom, just the electrons.
A chemical bond is an energy relationship between outer electrons and neighboring atoms.
32 electrons maximum
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.

2s^2 2p^6 8 electrons total
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.
Atoms emit energy as light when electrons move to a lower energy level
no, electrons can
electrons
The sharing of electrons in the outer energy levels of two atoms is called bonding.
