What is a gas?

100

This unit represent the atomic mass of an element.

What is Atomic Mass Unit (AMU)?

100

Group 18 is known by this name, as they can't bond with other elements in nature.

What is Noble Gases?

100

This bond is characterized by the loss/gain of electrons between elements.

What is an ionic bond?

100

This kind of property can only be observed when the object is permanently changed.

What is chemical?

200

This element has 2 atoms in a molecule of H2O

What is Hydrogen?

200

There are 16 electrons in Sulfur, as it has this many protons.

What is 16?

200

This trend increases as you go right and up the periodic table, with Fluoride being the highest.

What is electronegativity?

200

This subatomic particle is the key in all types of bonds.

What is electrons?

200

This is a column of elements on the periodic table.

What is a group?

300

This state change is when a solid turns directly into a gas, such as dry ice.

What is sublimation?

300

This subatomic particle has no atomic mass.

What is an electron?

300

This number represents the amount of protons in an element.

What is atomic number?

300

This is the largest amount of electron pairs that can be shared between any two atoms.

What is 3?

300

This is an element with 8 (or 2, in some cases) valence electrons.

What is atomic mass?

400

This element is the most reactive metal.

What is Francium?

400

This type of bond is characterized by having atoms float in a "sea" of electrons.

What is metallic?

400

This type of covalent bond has an unequal sharing of electrons.

What is plasma?

500

This type of diagram models the valence electrons of an atom.

What is a Lewis structure?

500

This trend is one-half the distance between two nuclei, and increases as you go left and down.

What is atomic radius?

500

This type of molecular force is stronger than the other.

What is intramolecular?

500

This is a "race track" that electrons follow around the nucleus.


What is orbital?
