Chemistry Right Ans - The science of structure and interactions of matter.
Matter Right Ans - Anything that has mass and takes up space.
Mass Right Ans - The amount of matter a substance contains.
Weight Right Ans - The force of gravity acting on a mass.
Element Right Ans - The simplest form of matter with unique chemical
properties.
Atom Right Ans - The smallest unit of matter that retains the properties of
an element.
Atomic Structure Right Ans - Consists of a nucleus surrounded by an
orbital.
Subatomic Particles Right Ans - Protons, electrons, and neutrons.
Nucleus Right Ans - The center of an atom.
Protons Right Ans - Positively charged subatomic particles with a mass of 1
atomic mass unit (amu).
Neutrons Right Ans - Neutral subatomic particles with a mass of 1 amu.
Electrons Right Ans - Negatively charged subatomic particles found in
orbitals around the nucleus.
Atomic Number Right Ans - The number of protons in the nucleus of an
atom.
Mass Number Right Ans - The number of protons and neutrons in an atom.
Isotopes Right Ans - Varieties of an element that differ in the number of
neutrons.
, Ions Right Ans - Charged particles with an uneven number of protons and
electrons.
Electrolytes Right Ans - Ions in water capable of conducting electricity.
Compounds Right Ans - Formed when different elements bond together.
Molecules Right Ans - Formed when two or more atoms bond together.
Chemical Bonds Right Ans - Forces of attraction holding atoms together.
Ionic Bonds Right Ans - Formed by the attraction between oppositely
charged ions.
Covalent Bonds Right Ans - Atoms sharing electrons to complete their
outer shells.
Double Covalent Bond Right Ans - Formed when each atom shares 2
electrons
Hydrogen Bonds Right Ans - Weak attraction between a slightly positive
hydrogen atom in one molecule and a slightly negative oxygen or nitrogen
atom in another molecule
Polar Vs. Non-Polar Bonds Right Ans - Described based on the equality of
electron sharing; nonpolar if sharing is equal (e.g., methane), polar if unequal
with one element 'pulling' electrons towards it (e.g., water)

- solvency
- polarity
- cohesion
- adhesion
- surface tension
Inorganic Compounds Right Ans - Inorganic compounds lack carbon and
are simple molecules
