|---|---|---|---|---|---|
| Periodic Table | Arranges all of the known elements in order of increasing atomic # (# of protons)
🗑
|
||||
| Metals | Becomes solid at room temperature (except mercury), ductile, malleable, conductor, high density, high melting point
🗑
|
||||
| Reactivity | Those metals at the bottom left corner of the periodic table are the most reactive, changes across to periodic table
🗑
|
||||
| Non-Metals | Dull, poor conductor, brittle, low density, low melting point, less reactive than metals
🗑
|
||||
| Metalloids | Elements on both sides of the zigzag line (staircase) have properties of both metals & nonmetals
🗑
|
||||
| Periods | Rows numbered from 1-7, Atomic # increases left-right, those in the same period have the same # of energy levels, chemical properties are not all similar
🗑
|
||||
| Groups | Aka families are the columns numbered 1-18, same # of valence electrons, chemical properties are very similar, group 1 (most reactive) & group 18 (most inert, aka stable)
🗑
|
||||
| Chemical Reaction | The ability of atoms to combine or separate w/ others to create substances, valence electrons are key to this
🗑
|
||||
| Stable Atom | Outer shell filled, don't want to bond w/ other atoms (inert)
🗑
|
||||
| Alkali Metals | Highly reactive, always combined, very soft
🗑
|
||||
| Alkaline Earth Metals | Always combined, not as reactive as Alkaline metals, important minerals for our body
🗑
|
||||
| Transition Metals | Less reactive, hard, useful building materials, jewelry, & coins, useful as oxides to make paint & pigments
🗑
|
||||
| Nobel Gases | Nonreactive, always found alone, used in balloons, light bulbs & neon signs
🗑

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.
