How are energy and frequency related - answer the higher the energy, the higher the
frequency
How are frequency and wavelength related? - answer the higher the frequency, the
lower the wavelength
Which neutral element does the following abbreviated configuration correctly describe?
1s2 2s2 2p6 - answer NE (Neon)
What is an atomic orbital? - answer It is a probability cloud that shows the probable
location of an electron within a given atom
piece of aluminum = 10g
volume of cylinder before immersion = 35.0mL
volume after immersion = 38.7mL
what is the density? - answer98.7mL-35mL = 3.7mL = volume
D=M/V
D=10g/3.7mL
D=2.7g/mL
If you remove 2 protons and 2 neutrons from a gold atom (Au), what new element is
formed (if any)? - answerIr (Iridium)
move 2 elements to the left on the PT
If you remove 2 protons and 2 electrons from a sulfur atom (S), what new element is
formed (if any)? - answerSi (Silicon)
move 2 elements to the left... then subtract the 2 electrons that are in Sulfur to get
neutral Silicon
