- 1Where are protons found?Nucleus of an atom
- 2What is the atomic number equal to?Protons found in the atom.
- 3What is the mass number equal to?The sum of protons and neutrons in the atoms nucleus.
- 4Atoms that share an atomic number but have different mass numbers?Isotopes
- 5Which electrons have lower energy levels and which electrons have higher energy levels.Electrons closer to the nucleus have lower energy levels
Electrons further away from the nucleus have higher energy levels. - 6Positively charged atomCation
- 7Negatively charged atomAnion
- 8What is the atomic weight and atomic number for this element?Atomic Weight- 58.693
Atomic Number- 28 - 9Find how many protons, neutrons and electrons are in this elementProtons is 28 (Atomic Number)
Neutrons is 31 (Number of Neutrons = Mass Number - Atomic Number)
Electrons is 28 (Protons and Electrons have to be equal) - 10Find how many protons, neutrons and electrons are in this elementProtons is 13 (Atomic Number)
Neutrons is 14 (Number of Neutrons = Mass Number - Atomic Number)
Electrons is 13 (Protons and Electrons have to be equal)
- 11What is the Planck relation (Frequency)?E=hf
Photon Energy
E=Energy of a photon
h=Planck's constant (6.626 x 10^-34)
f=Frequency of radiation - 12What is the Planck relation (Wavelength)?E=hc/λ
E=Energy of a photon
h=Planck's constant (6.626 x 10^-34)
λ=wavelength of radiation
c=the speed of light in a vacuum (3.00 x 10^8 m/s) - 13Line spectrumA line on the emission spectrum
that corresponds to a specific electron transition.
