Bases and Bubbles

protons

• Negatively charged particles found outside the nucleus of an atom

• Positively charged particle found inside the nucleus of an atom

• Neutral particles found in the nucleus of an atom

• Particles that determine the atomic mass of an atom

nucleus

• Central part of an atom that consists of protons and neutrons

• Outer shell of an atom where electrons are found

• A type of subatomic particle found in the nucleus

• The smallest unit of an element that retains its properties

electrons

• A positively charged particle found in the nucleus

• A negatively charged particle found in electron shells that move around the outside of the nucleus

• A neutral particle that exists within the nucleus

• A particle that is responsible for the strong nuclear force

base

• A substance that donates hydrogen ions (H+) in a solution.

• A substance that accepts hydrogen ions (H+) or that dissolves to release hydroxide ions (OH-).

• A substance that increases the concentration of hydrogen ions (H+) in a solution.

• A substance that reacts with acids to form salts.

neutrons

• A particle found inside the nucleus of an atom, it has no charge (is neutral)

• A positively charged particle found in the nucleus of an atom

• A negatively charged particle that orbits the nucleus

• A particle that is responsible for the chemical properties of an element

neutralisation

• A process that increases the acidity of a solution.

• A chemical reaction between an acid and a base which produces a more neutral solution (salt and water).

• A method to separate mixtures into their components.

• A reaction that only occurs in the presence of a catalyst.

mixture

• A substance made of two or more different chemical substances that are not bonded together

• A single chemical substance with a uniform composition

• A combination of elements that are chemically bonded

• A solution where one substance is dissolved in another

compound

• A substance made from two or more different elements that have been chemically joined

• A mixture of two or more substances that retain their individual properties

• A single element that cannot be broken down into simpler substances

• A solution where one substance is dissolved in another

mass number

• The total number of protons and neutrons in a nucleus

• The total number of protons in an atom

• The total number of electrons in an atom

• The total number of neutrons in a nucleus

molecule

• A single atom that cannot be broken down further.

• Two or more atoms chemically bonded or joined together.

• A type of chemical reaction involving only one reactant.

• A mixture of different substances without any chemical bonds.
