  • The question is asking about one orbital in the 4p sublevel. How many electrons can an orbital hold?

Try Again


Correct
Correct!

  • A 4p orbital can hold 2 electrons. Every orbital can only hold a maximum of 2 electrons that spin in opposite directions.

Next Question



Try again1
Try Again

  • The production of light occurs when an atom loses energy

Try Again


Correct1
Correct!

  • A line spectrum is created when the electrons of a metal salt fall from a high energy level to a low energy level.

Next Question



Try again2
Try Again

  • Higher shells have higher amounts of energy.

Try Again


Correct2
Correct!

  • When electron falls from a higher shell to a lower shell there is a loss of energy

Next Question



Try again3
Try Again

  • The outermost electrons are the electrons in the outermost s and p orbitals. Add up the total electrons in the outermost s and p orbitals to get the answer.

Try Again


Correct3
Correct!

  • Oxygen has 2 s electrons and 4 p electrons for a total of 6 electrons in its outermost level.

Next Question



Try again4
Try Again

  • The s sublevel has 1 orbital and the p sublevel has 3 orbitals. Each orbital can hold up to 2 electrons.

Try Again


Correct4
Correct!

  • The p sublevel can hold 6 electrons while the s sublevel can hold only 2.

Next Question



Try again5
Try Again

  • Add up the total number of electrons and then find the element with that atomic number.

Try Again


Correct5
Correct!

  • There are 7 total electrons. A neutral atom of nitrogen, with atomic number 7, would have 7 electrons in a neutral atom.

Next Question



Try again6
Try Again

  • Review the definitions on your notes.

Try Again


Correct6
Correct!

  • The definition of an orbital is the region where an electron is most likely to be found.

Next Question



Try again7
Try Again

  • C = wavelength x frequency

Try Again


Correct7
Correct!

  • 3 x 108 = (5.45 x 10-7)v v = 5.50 x 1014 Hz

Next Question



Try again8
Try Again

  • The lowest frequency waves have the highest wavelength.

Try Again


Correct8
Correct!

  • Red light has the longest wavelength and lowest frequency.

Next Question



Try again9
Try Again

  • The shortest wavelength waves have the highest frequency

Try Again


Correct9
Correct!

  • Gamma radiation has the highest frequency and lowest wavelength.

Next Question



Try again10
Try Again

  • Electrons behave like a particle and wave, but only move like one of them.

Try Again


Correct10
Correct!

  • Electrons move like a wave, as all matter does.

Next Question



Try again11
Try Again

  • Amplitude is the distance from the mid point to the highest or lowest point.

Try Again


Correct11
Correct!

  • B to C shows the distance from a crest to the midpoint.

Next Question



Try again12
Try Again

  • Remember that electrons must have different spins to occupy the same orbital.

Try Again


Correct12
Correct!

  • An up and a down arrow represent two electrons spinning in opposite directions.

Next Question



Try again13
Try Again

  • The kernel structure should have the last element in the row above, plus the valence shell of electrons. Make sure to have the proper number of electrons overall.

Try Again


Correct13
Correct!

  • The kernel structure is the ten electrons in Ne plus 7 more. [Ne]3s23p5

Next Question



Try again14
Try Again

  • E = hv

Try Again


Correct14
Correct!

  • E = (6.63 x 10-34)(5.78 x 1014)
