an aid that is used to identify organisms and that consists of the answers to a series of questions

the number of protons in the nucleus of an atom; It is the same for all atoms of an element

a chemical reaction in which heat is released to the surroundings during the reaction

a change that occurs when one or more substances change into entirely new substances with different properties

the fourth subdivision of the classification system located below phylum and above order.

a substance or molecule that participates in a chemical reaction

the center of an atom composed of the protons and neutrons which makes up the bulk of an atom

the broadest, most general category of the classification system. It is divided into 3 groups: Bacteria, Archaea, and Eukarya.

any compound that increases the number of hydronium ions when dissolved in water

a substance made up of atoms of two or more different elements joined by chemical bonds

a subatomic particle that has no charge and that is found in the nucleus of an atom

a coil that has a soft iron core and that acts as a magnet when an electric current is in the coil

the ratio of the mass of a substance to the volume of the substance (D = M / V)

the second most general category in the classification system. It is divided into 6 groups: Bacteria, Archaea, Protista, Fungi, Plantea, and Animalia.

the sixth subdivision of the classification system located below order and above genus.

a subatomic particle that has a negative charge

What a substance is called when no charge is present or it is a 7 on th pH scale

a substance that cannot be separated or broken down into simpler substances by chemical means

the last subdivision of the classification system located below genus. Only one organism can fit into all 8 levels. It makes up the second part of the scientific name and should be written in lower case.

All objects in the universe attract each other by the force of gravity. The size of the force depends on the mass of the object and the distance between the objects.

the smallest unit of an element that maintains the properties of that element

a chemical reaction that requires (absorbs) heat during the reaction

the reaction of an acid and a base to form a neutral solution of water and a salt

The gas that makes up the second biggest percentage of Earth’s atmosphere
