Lots of vocab words for chemistry! Grade 10

ionic bond


covalent bond


metallic bond

a chemical bond in which electrons are shared over many nuclei and electronic conduction occurs

chemical bond

an electrical force linking atoms




electrically charged atoms that have gained or lost electrons.


a negatively charged ion


a positively charged ion


a polyatomic ion that contains oxygen


Negative charged ions


a substance that dissolves in water to give a solution that conducts electric current

interstitial alloys

atoms of a different element "fill in gaps" in between the original metal atoms.


The loss of electrons from a substance involved in a redox reaction.

lattice energy


polyatomic ion

a charged group of covalently bonded atoms

monatomic ion

an ion formed from a single atom

electron sea model


properties of metals

shiny, ductile, good conductor of electric current, malleable, good conductor of thermal energy

sigma bond

a bond formed when two atomic orbitals combine to form a molecular orbital that is symmetrical around the axis connecting the two atomic nuclei

pi bond

A covalent bond in which the bonding electrons are most likely to be found in sausage-shaped regions above and below the bond axis of the bonded atoms


a description of a change in which a system absorbs energy from its surroundings



resonance structures

Lewis structures that have the same arrangement of atoms in a molecule but differ in the distribution of electrons among the atoms.


acids that contain hydrogen, oxygen, and a third element (usually a nonmetal)



octet rule


lewis dot

consists of the symbol of an element and one dot for each valance electron in an atom of an element


a connection that fastens things together

polar covalent bond


trigonal planar

an arrangement of atoms in the VSEPR model where the three pairs of electrons are placed 120 degrees apart on a flat plane.


The ability of an atom to attract electrons when the atom is in a compound



specator ions

ions present in solution that do not participate directly in reaction




a chemical substance formed as a result of a chemical reactionf

aqueous solution

a solution in which the solvent is water

net ionic equation

includes only those compounds and ions that undergo a chemical change in a reaction in an aqueous solution

complete ionic equation

an equation that shows dissolved ionic compounds as dissociated free ions

chemical equation

a representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products

replacement reaction

a chemical reaction in which one element replaces another in a compound, or when two elements in different compounds trade places

avogadro's number





compound that has water chemically attached to its ions and written into its chemical formula

molar mass

The mass in grams of one mole of any pure substance.
