2 The Father of the Periodic Table Dimitri Mendeleev _______________was the first scientist to notice the relationship between the __________Arranged his periodic table by ________ _______Said properties of ___________elements could be predicted by the properties of elements around the missing element_________later discovered that the periodic nature of the elements was associated with_________ _________, not atomic massMendeleevelementsatomic massunknownMoseleyatomic number2
3 What does the information in the box tell me? 1H1.008Atomic Number = # of __________protonsAtomic Mass = # of _________ + # of __________protonsneutrons__________ SymbolElemental3
4 The Periodic Table Column = Group or___________ _____ columns on the Periodic TableFamily18Row = _______________ rows on thePeriodic TablePeriod7
5 Metals, Nonmetals, and Semi-metals ____________ is the onlynonmetal on the ___________ sideHydrogen______________ are on the right of the stair-stepNonmetalsmetalMetals are on the _________ side of the stair- stepleftSemi-metals or_____________touch the stair-stepmetalloids5
6 Periods = RowsIn the periodic table, elements have something in common if they are in the same row.All of the elements in a period have the same number of atomic orbitals.Every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. It goes down the periodic table like that.
7 Groups = Columns (called Families) The elements in a group have the same number of electrons in their outer orbital.Every element in the first column (group one) has one electron in its outer shell. Every element on the second column (group two) has two electrons in the outer shell. As you keep counting the columns, you'll know how many electrons are in the outer shell.There are some exceptions to the order when you look at the transition elements, but you get the general idea.
