Chemistry of Life

Smallest particle of an element that retains the chemical properties of an element.

• Neutron

• Atom

• Electron

• Isotope

A proton is

• when two atoms share a bond

• electrically neutral, having no electric charge

• a subatomic particle with a single unit of positive electrical charge

• the smallest subatomic particle of an element

Matter is

• the physical "stuff" of the universe

• rocks, wood, metal, water, and animals

• anything that occupies space and has mass

• all three answers are correct

A pure substance that cannot be broken down into other substances by chemical means is a/an

• compound

• element

• molecule

• solution

When elements interact with other elements, they form more complex types of matter called

• solutions

• compounds

• covalent bonds

• molecules

A neutron is

• a neutral element

• a subatomic particle with a negative electrical charge

• a subatomic particle that is electrically neutral

• present in normal hydrogen

Electrons

• move rapidly on the inside of the nucleus

• are greater in mass than protons

• are fixed subatomic particles located on rings around the the nucleus

• is a subatomic particle with a single unit of negative electrical charge

What is formed when atoms are held together by an attraction caused by transferring or sharing electrons?

• an electron bond

• a chemical bond

• an iconic bond

• a chemical formula

A uniform mixture of two of more substances is called a

• solution

• concoction

• solute

• solvent

A solvent is

• the substance that is dissolved

• a compound that donates H+ ions to a solution

• a substance that dissolves another substance

• a compound that removes H+ ions from a solution
