Bases and Bubbles

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

nucleus

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

• Outer layer of an atom that contains electrons

• A type of subatomic particle found in the nucleus

• The energy level of an atom's electrons

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 resides in the nucleus

• A particle that is responsible for the strong nuclear force

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 solid states.

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 that retain their individual properties.

mass number

• The total number of protons and neutrons in a nucleus

• The total number of protons in a nucleus

• The total number of neutrons in a nucleus

protons

• Negatively charged particles found outside the nucleus of an atom

element

• A pure substance made up of only one kind of atom.

• A mixture of different types of atoms.

• A compound formed by chemical reactions.

• A solution that contains dissolved substances.

indicator

• A substance that changes color to indicate pH levels, such as blue and red litmus paper.
