What is Simplest pure substance made of only one type of atoms.
100
polarity
What is having positive and negative charges; H2O is polar.
100
Metalloids
What is Has both properties of nonmetals and metals; B, Si, Ge, As, Sb, Te.
100
The boiling point
What is the temperature at which a liquid changes to a gas. For water, it is 100 °C or 212 °F.
200
Sates of matter.
What is a liquid gass solid.
200
Compounds
What is Two or more elements chemically combined - sugar, salt, water, etc.
200
universal solvent
What is water will dissolve most substances.
200
Volume
What is the amount of space occupied by a substance; size.
200
Compressibility
What is refers to the ability of a given mass of a substance to decrease in volume in response to the application of an outside force
300
Reactants is
What is a left side of a chemical reaction.
300
Metals
What is found on the left side of the periodic table; tends to give away electrons.
300
Valence Number
What is the number of Electrons (e-) available in the outer shell - ex - Carbon has 8 electrons - 2 in the first shell and 6 in the outer shell - it has a valence number of 6 and needs 2 more to be full.
300
Mass
What is is the amount of matter in an object. Mass is different from weight.
300
Magnetism
What is refers to the ability of a substance to respond to a magnetic field. Metals such as iron, nickel, and cobalt are magnetic because they can be attracted by magnetic fields.
400
Products
What is a right side of a chemical reaction.
400
Non metals
What is found on the right side of the periodic table; tends to receive electrons.
400
Highly reactive metals
What is group 1 - alkali metals - Li, Na, K, Rb, Cs, Fr.
400
Density
What is is how much mass a material has per unit of volume. Denser materials have more matter in a given space than less dense
materials. Density is found by dividing the mass of an object by its volume.
400
Reactivity
What is describes whether a substance reacts easily with other substances. For example, most metals will react with acids.
500
Valence electrons.
What is E - found in the most outer shell.
500
homogenous mixture
What is a mixture that is uniform or the same; lemonade, paint, tea.
500
Law of Conservation of Matter
What is matter can never be created or destroyed - the number of atoms on the left side must equal the number on the right.
500
Odor
What is is the smell that a substance gives off. For example, vinegar has a pungent odor.
500
Flammability
What is describes the ability of a substance to ignite or burn.
