Bozeman Science Electron Configurations Quiz

What is electron configuration?

• The arrangement of electrons in atoms or ions.

• The number of electrons in each shell of an atom.

• The distribution of protons and neutrons in the nucleus.

• The energy required to remove an electron from an atom.

How can we quantify ionization energy?

• Using Coulomb's Law.

• Using periodic trends.

• Using spectroscopy.

• Using Avogadro's Law.

Which term describes the electrons in the inner shells of an atom?

• Core electrons

• Valence electrons

• Orbital electrons

• Subshell electrons

What effect do core electrons have on valence electrons?

• They shield valence electrons from the nucleus.

• They attract valence electrons to the nucleus.

• They determine the chemical reactivity of an atom.

• They determine the electron configuration of an atom.

According to Coulomb's Law, how does ionization energy change with the number of protons in an atom's nucleus?

• It decreases.

• It increases.

• It remains constant.

• It is unrelated to the number of protons.

Which element has a higher ionization energy: Hydrogen or Helium?

• Hydrogen

• Helium

What happens to the ionization energy as we move from Helium to Lithium in the periodic table?

• It decreases.

• It increases.

• It remains constant.

• It is not affected by the periodic table.

What term describes the arrangement of orbitals within subshells and shells?

• Electron configuration

• Quantum mechanics

• Periodicity

• Coulomb's Law

How many orbitals are in the d subshell?

• 1

• 3

• 5

• 7
