Ionization Energy Quiz

What is ionization energy?

• The energy required to remove an electron from a neutral atom

• The energy released when an electron is removed from a neutral atom

• The energy released when an electron is added to a neutral atom

• The energy required to add an electron to a neutral atom

What happens to the charge of an atom when an electron is removed?

• It becomes negatively charged

• It becomes a neutral ion

• It remains neutral

• It becomes positively charged

What trend is observed in the ionization energies of group one elements as you move down the group?

• Ionization energy increases

• Ionization energy remains constant

• Ionization energy decreases

• Ionization energy fluctuates

Which element requires more energy to remove an electron, hydrogen or lithium?

• Both require the same energy

• Lithium

• Hydrogen

• Neither requires energy

What is the electron configuration of a neutral lithium atom?

• 1s1

• 1s2 2p1

• 2s2 2p1

• 1s2 2s1

How does nuclear charge affect ionization energy?

• Nuclear charge only affects ionization energy in non-metals

• Higher nuclear charge decreases ionization energy

• Higher nuclear charge increases ionization energy

• Nuclear charge has no effect on ionization energy

What is electron shielding?

• The attraction between electrons and the nucleus

• The repulsion between inner and outer electrons

• The process of adding electrons to an atom

• The removal of electrons from an atom

What is the effective nuclear charge experienced by the outer electron in lithium?

• +1

• +2

• +3

• +1.3

How does the distance of an electron from the nucleus affect ionization energy?

• Distance only affects ionization energy in metals

• Distance has no effect on ionization energy

• Greater distance decreases ionization energy

• Greater distance increases ionization energy

Which factor primarily explains the trend in ionization energy down a group?

• Electron shielding

• Nuclear charge

• Distance from the nucleus

• Atomic mass
