Atoms and Periodic Table Tadym Mason

A particle that has a positive charge and is found in the nucleus of an atom

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

Particle that has no charge and is found in the nucleus of an atom

Particle that has a negative charge

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

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

States that when elements are arranged this way, similarities in their properties will occur in a regular pattern.

A horizontal row of emergents in the periodic table

A vertical column of elements in the periodic table

An element that is shiny and conducts heat and electricity well

An element that conducts heat and electricity poorly

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

Group 1 of the periodic table

Group 2 of the periodic table

Group 2-12 of the periodic table

Group 17 of the periodic table?

Unready ice element. Group 18 of the periodic table

A group of atoms that has lost or gained electrons and gains or loses energy

The number of protons an element has

The sum of numbers of protons and neutrons in the nucleus of an 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

(Amu) unit for measuring mass of an atom or molecule

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

The SI unit used to measure the amount of substance who’s number of particles is the same as the number of atoms of carbon
