---|---|---|---|---|---|
Ionization Energy | Energy it takes to remove an electron from an atom. Across L-R increasing because more protons means more pulling is needed as the shells get full. Down U-D decreasing because there are more shells that get in the way of the pull, so it is weaker.
🗑
|
||||
Electron Affinity | the change in energy when gaining an electron in gases. Across L-R energy when forced to gain an electron increases because the shells get full. Down U-D decreasing because the shells are in the way and decrease the pull of the atom.
🗑

||||
Electronegativity | An atom's ability to attract electrons to itself. the stronger subtracts the weaker one to get electronegativity. Little difference means same 2 gases(covalent). Big difference means 2 different M+NM (ionic). Higher than 1.7 is considered ionic
🗑

Atomic Size | radius size of elements. Across L-R decreasing because more protons. Down U-D increasing because of more shells.
🗑
|
||||
Octet Rule | having the same electron configuration as a noble gas.
🗑
|
||||
Diatomic Elements | when 2 of the same element bonds together
🗑
|

Ionic Compound | strong ionic bonds hold ions in lattice formation. extremely high melting point. solids
🗑
|
||||
Covalent Compound | polar molecules, strong intermolecular bonds, higher melting point than non-polar, water.
non-polar molecules, weak intermolecular bonds, lower melting point than polar, gas

Alternative System | Copper - (1)Cuprous, (2)Cupric
Mercury - (1)Mercurous, (2)Mercuric

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.
