T OR F??

electrons pair only after each subshell is full??

• TRUE

• FALSE

• TRUE

• FALSE

where do electrons occupy first?

• highest energy subshells

• lowest energy subshells

• middest energy subshells

• desiree's energy subshells

a quantum mechanical property of electrons that may be thought of as clockwise or counterclockwise orientation

• electron configuration

• spin

• vertical

unstable arrangements tend to ????

• become less stable by losing energy

• become more stable by losing energy

• become more stable by adding energy

T or F

electrons repel each other, which is why it is more stable to have only one electron in each orbital

• TRUE

• FALSE

• TRUE

• FALSE

NGSS.HS-PS1-3

the period, or row, number is the value of the principal energy shell,

(number of orbitals/number of rings around the nucleus)

T or F

filled energy levels are more stable than partially filled sub-levels, half-filled sublevels are more stable than other configurations

• TRUE

• FALSE

• TRUE

• FALSE
