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?

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.
