In the Bohr model of the hydrogen atom, an electron can exist between orbits
In the Bohr model of the hydrogen atom, an electron can exist between orbits.
112. In the Bohr model of the hydrogen atom, when an electron absorbs energy, it moves into a higher energy orbit.
113. When an electron moves directly from the n = 3 to the n = 1 orbit, it emits two photons.
114. There are three orbitals in the 2p sublevel.
115. The maximum number of electrons in the 2nd principal energy level is 8.
116. The maximum number of electrons in the 3rd principal energy level is 28.
117. There is one unpaired electron in a phosphorus atom.
118. The alkaline earth elements have one valence electron.
119. Sodium has a higher ionization energy than cesium because its valence electron is closer to the nucleus.
120. A fluorine atom is larger than a carbon atom because it has more protons and more electrons.
