
15: Families of Elements
16: Elements and the Periodic Table
17: Modeling Molecules
Chemical Interactions 1.2 and 1.3
CI 1.2: Elements make up the periodic table
 Elements can be organized by similarities
 Mendeleev and predicting new elements
 Reading the periodic table, groups and periods
 Trends in the periodic table
CI 1.3: The periodic table is a map of the elements
 The periodic table has distinct regions
 Most elements are metals: reactive, transition, rare earth
 Non metals and metalloids have a wide range of properties: halogens, noble
gases, metalloids
 (don't worry about radioactivity and half-life yet)
Vocabulary List:
Atomic mass-the average mass of the atoms of an element
Atomic mass number- the total number of protons and neutrons in an atom’s nucleus
Periodic table- a table of the elements arranged by atomic number that shows a
pattern in their properties
Group- a vertical column in the periodic table of the elements, elements have similar
properties
Period- a horizontal row in the periodic table of the elements, elements have varying
properties
Family- elements that share the same properties, noble gas, halogen, alkali metals,
alkaline earth metals
Reactive- likely to undergo a chemical change
Metals- an element that tends to be shiny, easily shaped, and a good conductor of
electricity (left side)
Nonmetals- an element that is not a metal and has properties generally opposite to
those of metal (right side)
Metalloids-an element that that has properties of both metals and nonmetals (middle)
Element- a substance that cannot be broken down into a simpler substance by ordinary
chemical change changes, consists of atoms of only one type
Chemical formula- an expression that shows the numbers and types of atoms joined in
a compound (H2O)
Compound- two different types of atoms bonded together
Molecule- a group of atoms that are held together by bonds so they move as one unit
Atom- the smallest particle of an element that has the chemical properties of that
element
Chemical bond- a non-contacting force that holds atoms together, can result from
attraction of opposite charges (protons to electrons, etc.)
Double-bond- two atoms share two pairs of electrons
Triple-bond- two atoms share three pairs of electrons
Transition metals- groups 3-12, some are the earliest known metals (copper), less
reactive, some are in food we eat
Valence shell- the area around the nucleus that holds the electrons (2,8, etc.)
Energy level- A possible level of energy that an electron can have in an atom
Bohr model- A model of the atom that places protons and neutrons in the nucleus and
electrons in orbits rotating about the nucleus at a great distance
Mendeleev- created the first periodic table, the current table is an adaptation of his
idea
Electron configuration- the arrangement of electrons in an atom
Lewis dot diagram- ????????
Main idea of the chapters:
SEPUP 15: the element families, arranging elements based on their properties
SEPUP 16: the periodic table, Medeleev (the maker of the table), how to read it
(groups, periods, why the elements are in what position)
SEPUP 17: Making molecules, bonding similar/ different atoms together, how many
bonds different elements have, how many each have for hydrogen
CI 1.2: Elements in the periodic table, why they’re in what location, what info can you
get based on an elements location
CI 1.3: Each part of the periodic table is a specific region (left side = metals, middle=
metalloids, right side= nonmetals, reactive metals, transition metals, etc.)
