Chemistry 5 (not Honors)

Rutherford’s atomic model could not explain the _____ of elements.

• orbits
• color
• energy
• chemical properties

scientist who proposed that electrons are found only in specific circular paths, or orbits, around the nucleus

• Dalton
• Bohr
• Thomson
• Democritus

Bohr proposed that an electron is found only in specific circular paths, or _____, around the nucleus.

• orbits
• quanta
• fuzzy areas
• rotations

Electrons jump away from the nucleus when they receive_____.

• an Uber ride
• color
• energy
• orbitals

The amount of energy required for an electron to disappear from one energy level and appear in another.

• a blast
• a quantum
• an orbit
• a volt

Higher energy levels are _____ the nucleus.

• farther from
• closer to

The specific region of space where there is a high probability of finding an electron; can hold up to 2 electrons; some shapes are round, dumbbell, and cloverleaf.

• energy level
• atomic orbital

the rule that tells us electrons occupy the orbitals of lowest energy first

• Hund's rule
• Pauli exclusion principle
• aufbau principle

the rule which tells us that in sublevels p,d, and f, which are made up of more than one orbital, only one electron will be in each orbital (in each box on the aufbau diagram). However, if there are more electrons, some or all orbitals will have two electrons.

• Hund's rule
• Pauli exclusion principle
• aufbau principle

the rule that tells us an atomic orbital may contain at most two electrons, each with opposite spin direction

• Hund's rule
• Pauli exclusion principle
• aufbau principle
