The period tells you how many energy levels an atom has.
the period number tells which is the highest energy level occupied by the electrons
The period number is the same as the energy level containing the valence electrons. For example, in period 4, the valence electrons are the 4s and 4p electrons.
Only nitrogen (but in the period 2) has 7 electrons in the neutral atom.
Oxygen is the only nonmetal with 6 Valence Electrons in period 2.
No. it is the term used to tell the electrons in an atom.
The Bohr model of the atom places electrons in orbits or "shells." Elements in the first period only have electrons in the first shell. Elements in the second period have electrons in the first two shells. Elements in the third period have electrons in the first three shells, and so on.

non-metals have between 3 and 8 electrons in the outer shell. You can tell how many they have by looking at which period they're in on the periodic table, period 13 elements have 3, period 15 elements have 5 ect.
The period number is the same as the energy level containing the valence electrons. For example, in period 4, the valence electrons are the 4s and 4p electrons.
The periods in the periodic table tell you the energy level where the last electrons are being added. So, in period 1, the outermost electrons are in the first energy level or shell. In the 3rd period, the outermost electrons reside the the 3rd energy level, and so on.
Only nitrogen (but in the period 2) has 7 electrons in the neutral atom.
It tells you the number of cations in the outer energy level of the element's atomic mass
The period that the element's in is the same number of how many valence electrons (energy level of outer electrons) there are in the element...
Oxygen is the only nonmetal with 6 Valence Electrons in period 2.
