Chapter 2 - Atoms, Molecules, and Ions

Metal

conducts heat and electricity well, whereas a nonmetal does not.

Hydrocarbons

are the most basic organic molecules, containing solely carbon and hydrogen atoms.

Hydrocarbons

are the most basic organic molecules, containing solely carbon and hydrogen atoms.

Hydrates

are substances that contain a certain quantity of water molecules.

metalloid

A(n) is a substance with qualities that are halfway between metals and nonmetals.

hydroxide ions

A base is a material that, when dissolved in water, produces (OH)

Al3+

is the cation, and O2 is the oxygen anion.

Dalton

did not attempt to define the structure or composition of atoms since he had no concept of what an atom was.

high voltage

The negatively charged plate, termed the cathode, emits an invisible beam when the two metal plates are coupled to a(n) source.

Acids

that contain hydrogen, oxygen, and another element are known as oxyacids.

Chemists

employ chemical formulas to express the chemical symbols that makeup molecules and ionic compounds.

H2

Because it only has two atoms, the hydrogen molecule, abbreviated as , is known as a diatomic molecule.

H2O

Water () and ammonia (NH3), like ozone, are polyatomic molecules.

allotrope

A(n) is a type of element that exists in two or more different forms.

majority of matter

The is made up of molecules or ions created by atoms.

Polyatomic molecules

are molecules that have more than two atoms.

Aluminum Oxide

is a type of oxide of aluminum.

Zinc iodide

is formed when the zinc cation Zn2+ and the iodine anion I interact with.

acid

A(n) is a chemical that, when dissolved in water, produces hydrogen ions (H+)
