Pre test questions for Wednesdays test

When electrons occupy the lowest energy levels available to them the electrons are said to be in:

• the ground state

• a radiation state

• an excited state

• a deficient state

Which occurs when an atom in an excited state returns to the ground state?

• It gives off energy.

• It becomes less stable.

• It acquires more energy.

• It looses an electron.

All electrons possess a certain amount of energy. When electrons absorb more energy, they are boosted to higher energy levels. An electron that has absorbed more energy is said to be:

• in its ground state

• in an indivisible state

• in an excited state

• more energetic than other electrons

How many electrons may be held in the p sublevels?

• 2

• 6

• 8

• 10

The regions of space best represented by a spherical shape are the orbitals labeled:

• s

• p

• d

• f

The d orbitals would not be found at which one of the following energy levels?

• 2

• 3

• 4

• 5

When an atom goes from an excited state to the ground state, the charge of the atom:

• increases

• decreases

• remains the same

What is the number of electrons permitted in the d sublevel of the 3rd energy level?

• 3

• 9

• 10

• 18

Which sublevel contains electrons with the highest energy?

• 3p

• 2p

• 3s

• 4s

Which element contains the first d electron?

• K

• Mn
