Anatomy- The Chemistry of Life

Because it helps explain how living things function at a molecular level

Because it only deals with non-living things

Because chemistry is unrelated to biology

Because it is only needed for laboratory experiments

Protons and neutrons

Electrons and protons

Neutrons and electrons

Only protons

Carbon, oxygen, hydrogen, and nitrogen

Carbon, calcium, sodium, and iron

Oxygen, magnesium, phosphorus, and zinc

Hydrogen, iron, sodium, and calcium

Isotopes have the same number of protons but different numbers of neutrons.

Isotopes have different numbers of protons and neutrons.

Isotopes have the same number of neutrons but different numbers of protons.

Isotopes have different charges.

They have different numbers of neutrons.

They are different elements.

Determining the age of rocks and fossils

Curing cancer

Killing bacteria that cause food spoilage

Making water safer to drink

A compound has different properties from the elements that compose it.

A compound is made of only one element.

A compound always has the same properties as its elements.

A compound cannot be broken down into simpler substances.

Chemical bonds

Protons

Neutrons

Nuclear forces

Ionic bonds and covalent bonds

Hydrogen bonds and metallic bonds

Van der Waals forces and ionic bonds

Covalent bonds and metallic bonds

Ionic bonds are formed when electrons are transferred from one atom to another.

Ions of opposite charges are attracted to each other in ionic bonds.

Ionic bonds involve the sharing of electrons between atoms.

Ionic bonds only occur between nonmetals.

Unequal sharing of electrons between atoms

Equal sharing of electrons between atoms

Presence of only one type of atom

Absence of covalent bonds

Oxygen

Hydrogen

Both equally

Neither

Hydrogen bonds form between the hydrogen atom of one water molecule and the oxygen atom of another.

Hydrogen bonds are responsible for the cohesion of water molecules.

Hydrogen bonds occur within a single water molecule.

Hydrogen bonds are stronger than covalent bonds.
