Want this question answered?
When a light wave hits an object, what happens to it depends on the energy of the light wave. The waves can be reflected or scattered off the object; waves can be absorbed by the object; waves can be refracted through the object; waves can pass through the object with no effect.
period of time?
That's the object's 'speed'.

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 period tells you how many energy levels an atom has.
An overstatement of ending inventory in one period results in
Only nitrogen (but in the period 2) has 7 electrons in the neutral atom.
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...
the period number tells which is the highest energy level occupied by the electrons
the period number tells which is the highest energy level occupied by the electrons
the period number tells which is the highest energy level occupied by the electrons
Oxygen is the only nonmetal with 6 Valence Electrons in period 2.
The period number tell about the energy levels occupied by electrons
they get more electrons the farther right the get
