Metals
Help!
|
|
||||
|---|---|---|---|---|---|
| Periodic Table | Arranges all of the known elements in order of increasing atomic number(# of protons). Order generally coincides with increasing atomic mass too.
🗑
|
||||
| Metal | Solid at room temperature, shiny luster, ductile(bendable), malleable(hammered with out shattering), good conductors of heat and electricity, high density, high melting points,re activity bottom left are the most atractive
🗑
|
||||
| Non-metals | No luster(dull appearance), poor conductors, brittle(break easily), not ductile(bendable), Not malleable(hammered without shattering), low density, low melting point, less reactive than metals
🗑
|
||||
| Metalloids | Elements on both sides of the zigzag line have properties of both metals and non metals
🗑
|
||||
| Periods | The periods are the rows on the periodic table #1-7, The atomic number increases as you go left to right, those in the same period have the same number of levels and shells, chemical properties are not all similar.
🗑
|
||||
| Groups | The groups or families on the periodic table are the columns that are left to right #1-18, same number of valence electrons, chemical properties are very similar, Group 1 is the most reactive and group 18 is the least
🗑
|
||||
| Reactivity | The ability to combine or separate with other atoms to create new substances, valence electrons are the key to this process, re activity changes across the periodic table.
🗑
|
||||
| Happy stable atom | Having its outer most energy level filled with electrons, These atoms do not want to bond with others atoms, Helium is the exemption because it is happy with only two valence electrons
🗑
|
||||
| Alkali Metals | Highly reactive.They are so reactive they are never found uncombined in nature, metals soft enough you can cut them with a butter knife
🗑
|
||||
| Alkaline Earth metals | Fairly reactive, not as reactive as alkali metals but still never found uncombined in nature, serves as important minerals in our body
🗑
|
||||
| Transition Metals | Less reactive metals, hard and dense metals that are useful as building materials such as jewelry and coins
🗑
|
||||
| Noble gases | Un re active gases

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.
