What does the periodic table do (what is it's function?)
|
The periodic table organizes all the known elements and gives a good deal of information about each one.
|
|
Name the 4 physical properties of metals
|
1) good conduction of heat and electricity
2) malleability (can be hammered into thin sheets) 3) ductility (can be pulled into wires) 4) (often) lustrous appearance |
|
Metals tend to (gain/lose) electrons to form positive ions.
|
lose
|
|
Nonmetals
|
elements that appear in the upper right hand corner of the periodic table. chemically, they tend to gain electrons to form negative ions, but can also share electrons to form covalent bonds.
|
|
Metalloids (or Semimetals)
|
elements bordering the "staircase"- have properties between true metals and true nonmetals
(Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, Astatine) |
|
Group or Family (of the Periodic Table)
|
vertical columns of elements in the periodic table
|
|
Name for the elements in group 1A of the periodic table
|
Alkali Metals
|
|
Name for the elements in group 2A of the periodic table
|
Alkaline Earth Metals
|
|
Name for the elements in group 6A (or 16) of the periodic table
|
Chalcogens
|
|
Name for the elements in group 7A (or 17) of the periodic table
|
Halogens
|
|
Name for the elements in group 8A (18) of the periodic table
|
Noble Gases
|
|
Representative Elements
|
Elements in longer columns (the A groups: 1, 2, 13-18)
|
|
Transition Elements
|
Elements in the "B groups"
|
|
Inner Transition Elements
|
The elements in the rows below the main body of the periodic table- each row is named after the elements it follows in the main body of the table: Lanthanide and Actinide
|
|
Periods
|
the horizontal rows of the periodic table- these are simply numbered as you go down (period 1 contains Helium and Hydrogen)
