The energy of a photon, or quantum is related to it's: Frequency
The behavior of Cathode rays produced in a glass tube containing gas at low pressure led scientists to conclude: The rays are composed of negatively charged particles.
The set of orbitals that are dumbell-shaped and directed along the XYZ and axes are called: P Orbitals
The element with electron configuration 1s22s22p63s23p2 is" Silicon z=14
Visible light, X rays, Infrared Radiation and Radio Waves all have the same: Speed
Notation for the three highest energy electrons.
A 3 dimensional region around a nucleus where an electron may be found: Orbital
Product of the frequency and the wavelength equals the: Number of waves passing a point in a second B. Speed of the wave C. Distance between wave crests or D. Time for one full wave to pass.
An atom is electrically neutral because: The number of electrons are equal to the number of protons.
The number of orbitals for D is: Five
According to the particle model of light cannot eject electrons from metals because: The energy of the light is too low. Photons of light need to have enough energy to eject an electron. The energy of a photon is given as E = (Planck's constant) * (frequency)
As the atomic number increased, the atomic radius decreases.
