|---|---|---|---|---|---|
| malleable | able to be flattened (gold (Au) is the most)
🗑
|
||||
| ionization energy | the amount of energy needed to remove an electron
🗑
|
||||
| cation | an ion with a positive charge
🗑
|
||||
| anion | an ion with a negative charge
🗑
|
||||
| ion | a charged particle
🗑
|
||||
| alkaline/alkali metal | a highly reactive metal; is never found naturally in its elemental state; its reactivity increases with the number of protons; has low electronegativity; is found in group 1 of the Periodic Table; has one valence electron; has lowest ionization energy
🗑
|
||||
| alkaline/alkali earth metal | has less extreme properties than in group 1; is found in group 2 of the Periodic Table; has two valence electrons
🗑
|
||||
| family/group | each vertical column of the Periodic Table
🗑
|
||||
| Coulomb's law | states that opposite charges attract and like charges repel; force depends on number of charge and distance in charges
🗑
|
||||
| periodic law | states that chemical and physical properties of elements follow a repeated pattern
🗑
|
||||
| diatomic element | an element that appears naturally as two atoms joined; is too unstable to remain single (hydrogen, oxygen, fluorine, bromine, iodine, nitrogen, chlorine; remember scientist "Dr. HOFBrINCl")
🗑
|
||||
| halogen | a highly reactive nonmetal; is found in group 17 of the Periodic Table; has seven valence electrons; is toxic; forms salt when combined with group 1; is also diatomic; has very high electronegativity and ionization energy
🗑
|
||||
| period | each horizontal row of the Periodic Table
🗑
|
||||
| ductile | able to form wire
🗑
|
||||
| electronegativity | tendency of an atom to take another atom's electrons
🗑
|
||||
| metalloid/semimetal | an element whose properties are intermediate between those of metals and solid nonmetals; is an electrical semiconductor; may be a nonmetal that can combine with a metal to form an alloy (boron, silicon, germanium, arsenic, antimony, tellurium)
🗑
|
||||
| metal | has a low ionization energy; is ductile; is malleable; tends to have electrical and thermal conductivity; has luster; tends to form cations
🗑
|
||||
| nonmetal | tends to be a gas, liquid, or network solid (forms repeating patterns of atoms); tends to gain electrons and form anions; if solid, tends to be brittle; is a poor conductor; lacks luster
🗑
|
||||
| transition metal/transition element | can be found in groups 3 to 12 in the Periodic Table; can form more than one type of cation; forms a colored solution (copper, cobalt, niobium, manganese, iron, nickel)
🗑
|
||||
| noble/inert/monatomic gas | an element occurring as a single atom; is completely nonreactive; its density increases with period on the Periodic Table
🗑
|
||||
| ionic radius | the radius of an atom's ion
🗑
|
||||
| atomic radius | a measure of the size of a chemical element's atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding cloud of electrons
🗑

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.
