|
||||
| atomic orbital | a region in space around the nucleus of an atom where there is a high probability of finding an electron
🗑
|

🗑
|
||||
| energy level | a region around the nucleus of an atom where an electron is likely to be moving, numbers 1-7
🗑
|
||||
| ground state | the lowest energy level occupied by an electorn when an atom is in its most stable energy state
🗑
|
||||
| spectrum | the range of wavelengths and frequencies making up light
🗑
|
||||
| alkali metal | Group 1A elements, s-block, very reactive
🗑
|
||||

🗑
|
||||
| group | column on the periodic table, represents a "family" of elements with similar chemical and physical properties
🗑
|
||||
| halogen | Group 7A elements, p-block, salt-forming elements
🗑
|
||||
| noble gas | Group 8A elements, p-block, non-reactive elements due to the fact that the outermost s and p sublevels are filled
🗑
|
||||
| period | row on the periodic table, represents the energy level for s and p orbitals
🗑

🗑
|
||||
| wavelength | (lambda) the distance between two wave crests
🗑
|
||||
| frequency | (nu) the number of wave cycles to pass a given point per unit of time
🗑
|
||||
| photon | a single quantum of light, part of Einstein's idea that light can be seen as a wave OR a particle
🗑
|
||||
| excited state | electrons that have jumped to a higher, more unstable energy level
🗑
|
||||
| energy sublevel | s, p, d, and f
🗑

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.
