The elements found to the right of the staircase on the periodic table of elements
What are the non metals?
Type of mixture where particles are not uniformly scattered.
What are heterogeneous mixtures.
The number of Protons in a Hydrogen atom.
What is 1?
Molecular compounds made of two atoms of the same element.
What are diatomic molecules?
Substances that go into a chemical reaction.
What are the reactants?
What are halogens?
Heterogeneous mixtures composed of fine particles evenly distributed throughout a second substance
What is a colloid?
The number of protons in an atom.
What is the atomic number?
The type of compounds where you use prefixes when naming them.
What are molecular compounds
A substance that speeds up a rate of reaction without being changed itself.
What is a catalyst?
Metals that are highly reactive and sometimes require special storage because they even react with water!
What are the alkali metals?
A heterogeneous mixture made of large particles that are uniformly mixed but will settle if left undisturbed.
The number of protons and neutrons in an atom.
What is the atomic mass?
The type of compound formed when a metal and a non metal join.
What are ionic compounds?
The oxidation of metals or rocks in the presence of air and moisture.
What is rust?
Gases that have no unpaired electrons in their outer shell and are therefore very unreactive.
What are the Noble Gases?
A type of colloid where liquids are suspended in liquids.
What are emulsions?
The number of neutrons in an atom of Flourine.
What is 10?
The chemical formula for Sodium Chloride.
What is NaCl?
The highly exothermic reaction of a substance with oxygen. Cellular respiration is an example of this type of reaction.
What is combustion?
What are non metals.
The law that says that compounds are pure substances that contain two or more elements will be combined together in fixed or definite proportions.
What is the Law of Definite Composition?
A pure substance made of only one type of atom.
The Chemical name for NI3
What is Nitrogen triodide.
In a chemical reaction the total mass of the products is always equal to the mass of the products.
What is the Law of Conservation of Mass?
