|---|---|---|---|---|---|
| rows on periodic table | periods
🗑
|
||||
| columns on periodic table | groups
🗑
|
||||
| representative elements | valence electrons are in s and p subshells
🗑
|
||||
| Nonrepresentative elements | includes transition elements; valence electrons are in d subshells too
🗑
|
||||
| Atomic Radius trend | Period: decreases cuz elements hold on to their electrons tighter
Group: increases bcuz new outer layers make elements bigger
🗑
|
||||
| Ionization E | E required to remove an electron from a gaseous atom or ion
🗑
|
||||
| Ionization E Trend | Period: increases cuz it gets harder to take an electron from the element since the electrons are more tightly bound
Group: decreases bcuz electrons are farther from nucleus making it easier to remove them
🗑
|
||||
| Electron Affinity | the ease with which an atom can accept an electron
🗑
|
||||
| Electron Affinity Trend | Period: Increases cuz halogens really want one more electron to fill octet
Group:
🗑
|
||||
| Electronegativity | measure of the attraction an atom has for electrons in a chemical bond
🗑
|
||||
| Electronegativity Trend | Period: increases (F is most electronegative) cuz halogens really want extra electron to fill octet
Group: decreases
🗑
|
||||
| malleability | ability of a metal to be hammered into shapes
🗑
|
||||
| ductility | ability of a metal to be drawn into wires
🗑
|
||||
| metals | on left side and in middle of PT; good heat/electricity conductors; electrons can be removed easily
🗑
|
||||
| Nonmetals | right side of PT; poor conductors; high electronegativity and ionization E; gain electrons easily
🗑
|
||||
| Metalloids | semimetals; B Si As Te Ge Sb
🗑
|
||||
| Alkali | Group 1 metals; react with Halogens well, low electroneg, low IE, high atomic radius, 1 e-
🗑
|
||||
| Alkaline | Group 2 metals; low electroneg and IE, smaller radius than alkali, 2 e-
🗑
|
||||
| Halogens | Group 7, highly reactive, 7 e-, high electroneg and IE, small atomic radius
🗑
|
||||
| Noble Gases | Group 8, nonreactive, full octets, no electroneg, super high IE
🗑
|
||||
| Transition Metals | d-block, hard, high mp and bp, low IE, positive oxidation states
🗑
|
||||
| Oxidation States | ability of an atom to oxidize/reduce another atom in chemical compound, related to e- gained, lost, or used
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
