A subatomic particles that has a positive charge and that is found in the nucleus of an atom.

An atoms central region which is made up of protons and neutrons

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

A subatomic particle that has a negative charge

A region in an atom where there is a high probability of finding electrons

An electron that is found in the outermost shell of an atom and that determines the atoms chemical properties

The law that states that the repeating chemical and physical properties of elements change periodically with the atomic number a of the elements

A horizontal row of elements in the periodic table

A vertical column of elements in the periodic

An element that is shiny and conducts heat and electricity well

An element that conducts heat and electricity poorly

An element or compound that conducts electric current better than an insulator but not as well as a conduct does

On of the elements of group 1 of the periodic table

Make up the second column of elements from the left edge of the periodic table

One of the elements of groups 3-12 of the periodic table

One of the elements of group 17 of the periodic table

An unreactive element of groups 18 of the periodic table

An atom or group of atoms that has lost or gained one or more electron and has a negative or positive charge.

The number of protons and electrons in an atom

The sum of neutrons and protons in the nucleus in the atom

An atom that has the same number of protons as other atoms of the same element do but that has a different number of neutrons

A unit of mass that describes the mass of an atom or molecule; It is exactly one twelfth of the mass of a carbon atom with mass number 12

The weighted average of the masses of all naturally occurring isotopes of an element

The si base unit used to measure the amount of a substance whose number of particles is the same as the number of atoms of carbon in 12g of carbon 12
