Understanding the Main Ideas Atomic Number Element Symbol Element Name Atomic Weight
Long Answer: 5) I could use the facts above to tell me the number of protons, neutrons and electrons in the element. 6) Mendeleev arranged the elements in order of increasing atomic mass. 7) Elements in the same column (which is called a family/group) have the same chemical properties. 8) As you move from left to right, the number of valence electrons increases. These electrons are involved in bonding with other atoms. 9) Based on the element’s position in the periodic table I can predict the following: its chemical properties, how many valence electrons it has, how reactive it is and whether it is a metal or non-metal.
Building Vocabulary 10) A(n) ________________ is involved in the transfer or sharing of electrons 11) A(n) _________________ is positively charged particle in the nucleus 12) An element’s ______________ is its row in the periodic table 13) The central core of an atom is called the ___________________. 14) A(n) ___________ carries a negatively electrical charge 15) Mendeleev was the first to arrange elements according to their properties in a(n) ________________________. 16) Elements in a(n) ___________ or ____________ of the periodic table have similar characteristics. 17) A(n) ___________ is a particle with no charge 18) Scientists use the _________ to measure the mass of the particles within an atom. Valence electron Proton Period Nucleus electron Periodic table family group neutron AMU
Practice- Together: Find the Element: Notes Periods: They are rows that go side to side. Elements have very different characteristics. They behave like cousins. (there are 7) Families or Groups: They are columns that go up and down. Elements have similar properties. They behave the same like family members. (there are 18) Practice- Together: Find the Element: Period 1 Family 18 _______ Period 3 Family 18 ______ Period 2 Family 16 _____ Helium Argon Oxygen
Metals and Non-Metals Notes Shiny Good conductors of heat and electricity High density High melting point Usually solids Malleable/Shapeable Can be magnetic Non-Metals Dull Bad conductors of heat and electricity Low density Low melting points Usually gases Not Malleable/Shapeable

It separates metals from non-metals. The first family, Group/Family #1 (Alkali). Lithium, Sodium, Potassium Group/Family #17 Halogen Na + Cl = Table Salt Like Royalty, they don’t associate with common elements
horizontal The atomic number increases. The atomic mass increases. K Ne Mg Fe They are in the same Group/Family.
