Rutherford used gold foil to discover this part of the atom.

The chemical Formula for Lithium Nitride

This is the name for the column of elements on the periodic table

This rule describes the tendency of atoms to want 8 electrons in their outer energy level in order to be more stable.

The electron Dot diagram for Oxygen has this many dots and looks like this

This model of the atom has electrons evenly spaced out evenly throughout the entire atom.

What two oxygen atoms look like when bonded to one Carbon atom.

Mendeleev arranged his periodic table according to this property. The periodic table is now arranged by atomic number.

This is a chemical that will speed up a chemical reaction, but will not be altered during the reaction.

If you increase the temperature of a reaction, the reaction rate will do this.

A cathode ray was used to discover this part of the atom.

The measure of how much an atom attracts electrons

These elements are all found in group 17 of the periodic table

These are the main three factors that can control the reaction rate of a chemical reaction.

A substance that slows down a chemical reaction.

If an atom has an atomic number of 17 and and atomic mass of 42 it will have this many neutrons.

The type of bond that is formed when atoms create a pool (sea) of electrons

These atoms react rapidly and violently with water

The law that states that the mass before a reaction must be the same as the mass after a reaction

These elements are found in groups 3-12 and are often good conductors of electricity and heat.

This type of particle is released when an atom decays into a helium nucleus and a slightly smaller atom.

The number of electrons in the second energy level of an atom.

This element is a metal, but has a melting point so low that it will melt in your hand.

A reaction that releases energy as a product

When two atoms have very different electronegativities the will make this type of bond.
