Explain the trends of the periodic table based on the elementsrsquo valence electrons and atomic numbers

Period is the term used to describe a horizontal row on the periodic table

Group and family are terms used to describe a vertical column on the periodic table

Metals

Metals have 3 or fewer valance electrons Metals lose electrons when making an ionic bond Metals are good conductors malleable and ductile

Metalloids

Metalloids have some characteristics of metals and some of nonmetals they border the line between metals and nonmetals on the periodic table

Non-Metals

On the EOC students must

Locate referenced elements when prompted with a period number or group number

Determine a given elementrsquos atomic number (number of protons)

Determine the number of electrons that an atom of a given element contains (the same as the number of protons-atomic number)

Determine how many energy levels are occupied in a given element (recognize that the period in which an element appears on the periodic table indicates the number of occupied energy levels)

bullFor example all elements in period 4 have four occupied energy levels

Recognize a given elementrsquos atomic mass (the weighted average of the masses of the naturally occurring isotopes of the element)

It is always larger than the atomic number and generally increases from left to right on the Periodic Table

Determine the number of valence electrons (electrons in the outer-most energy level) for selected groups of elements when given the elementrsquos group number or name
