What does atomic radius measure?
The approximate size of an atom, often described as the distance from the nucleus to the outermost occupied electron shell.
100
What is ionization energy?
The energy required to remove an electron from a gaseous atom.
100
What does electronegativity describe?
An atom's ability to attract shared electrons in a chemical bond.
100
What are valence electrons?
Electrons in an atom's outermost occupied shell.

As you move down a group on the periodic table, what happens to atomic radius? Why?
It increases because additional electron shells are added.
200
What generally happens to ionization energy as you move down a group?
It decreases because outer electrons are farther from the nucleus and more shielded.
200
What happens to electronegativity as you move from left to right across a period?
It generally increases.
200
What type of ion has a positive charge?
Cations

In Scream, what is the name commonly used for the masked killer?
Ghostface
300
As you move from left to right across a period, what generally happens to atomic radius?
It decreases because the increasing nuclear charge (#protons) pulls electrons closer.
300
What generally happens to ionization energy from left to right across a period?
It increases because the nucleus attracts electrons more strongly.
300
What happens to electronegativity as you move down a group?
It generally decreases.

What is the fear of spiders called?
Arachnophobia
400
Which atom has the larger atomic radius: sodium (Na) or chlorine (Cl)? Why?
Sodium (Na). They are in the same period, and atomic radius generally decreases from left to right.
400
Which element has the greater ionization energy: sulfur (S) or magnesium (Mg)?
Sulfur. It has a greater effective nuclear attraction for its outer electrons. (more protons attract create a stronger attraction between its electrons)

Which element is the most electronegative on the periodic table?
Fluorine (F).

Which type of element gains electrons?
Nonmetal

Rank these elements from largest to smallest atomic radius: Li, Na, K.
K > Na > Li. Radius increases down a group.
500
Rank these elements from lowest to highest first ionization energy: Al, In, Ga
In < Al < Ga. Ionization increases from bottom to top.
500
Which atom attracts shared bonding electrons more strongly in an O–H bond: oxygen or hydrogen? Explain.
Oxygen, because it has a higher electronegativity than hydrogen.
