The Second Energy Level of an Atom

Question

The second energy level of an atom
A) has four orbitals
B) can hold eight electrons
C) is a lower energy level then the first energy level
D) both a and b above

Accepted Answer

The second energy level of an atom can hold a maximum of eight electrons, and it consists of four orbitals (1 s, 2 s, and two 2 p orbitals). Option C is incorrect; the energy levels are numbered consecutively, with the first level being the lowest energy level.
