Presentation Transcript

Question 1

Try Again

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

Try Again

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

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

Correct!

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

Next Question

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

Correct!

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

Next Question

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

Try Again

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

Try Again

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

Correct!

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

Next Question

Correct!

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

Next Question

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.
