Definition: Solution
Solid dissolved in liquid.
Definition: Dependent Variable
The thing that you measure.
Definition: Ionic Bond
Metal + Non-Metal Bonded Together
Definition: Atomic Number
Number of Protons (This defines the element)
Definition: Covalent Bond
Non-Metal + Non-Metal Bonded Together
Definition: Controlled Variable
The things that you keep the same.
Definition: Istope
Same chemical elements that have a different mass. They are the same element because they have the same number of protons. They have different mass because they have different number of neutrons.
Definition: Solvent
Liquid that Solid dissolves in.
Definition: Element
A substance made up of one type of atom.
Explain what happens in Dissolving.
One substance ‘apparently’ disappears into another, due o the forces of attraction that occur between the particles that make up the substances.
Definition Atomic Mass Number
Number of Protons + Number of Neutrons.
Definition: Ion
An electrically charged particle. (Formed by the loss or gain of electrons.
Definition: Atom
The smallest particle making up an element. The chemical building blocks of matter.
Definition: Solute
Solid that dissolves.
Definition: Metallic Bond
Metal + Metal Bonded Together
Definition: Molecule
A substance made up of two or more chemically bonded atoms.
Definition: Compound
A substance made up of two or more different atoms.
Definition: Independent Variable
The thing that you change throughout the experiment.
