|---|---|---|---|---|---|
| group/family | vertical column of elements in the periodic table; have the same number and arrangement of valence electrons
🗑
|
||||
| period | horizontal row of elements in the periodic table
🗑
|
||||
| valence electrons | electrons located in the last energy level/shell of an atom
🗑
|
||||
| metals | element that have the property of shiny luster, ductility, and malleability. most elements are metals
🗑
|
||||
| luster | the way a material reflects light
🗑
|
||||

🗑
|
||||
| ductile | able to be drawn into thin wires [metals]
🗑
|
||||
| nonmetals | elements that have different property then metals; dull and brittle; located to the right of the zig zag line on the periodic table
🗑
|
||||
| halogens | elements that make up group 17 on the periodic table; most likely to form negative ions
🗑
|
||||
| noble gasses | elements that make up group 18 on the periodic table; all elements contain a stable number of valence electrons

🗑
|
||||
| metalloids | elements that have the property's of both metals and non metals
🗑
|
||||
| isotope | atom of a elements that has the same number of protons as the other atom, but a different number of neutrons
🗑
|
||||
| ion | charged atom formed when the atom gains or looses electrons
🗑
|
||||
| ionic bond | bond formed between atoms that have gained or lost electrons; one atom transfers electrons to another
🗑
|
||||
| covalent bond | bond formed when atoms share electrons
🗑
|
||||
| subscript | little numbers below the line that tells you how many atoms of an element there are in a molecule
EX: H2O, the subscript is 2
🗑
|
||||
| coefficient | regular sized numbers in front of a formula that tells you how many molecules there are
EX: 3 H2O, the coefficient is 3
🗑
|
||||
| reactant | molecules to the left of the arrow in the chemical equation
🗑

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.
