-
Are atoms with unpaired electrons unreactive?
- No, electrons that are unpaired are highly reactive.
-
Where are electrons most likely to be found?
- Sub-Shells/orbitals named s,p,d,f orbital
-
How many electrons can each orbital contain?
-
How are the number of main shells determined?
- Distance of the main shell from the nucleus (volume)
-
How is it best to find the electron configuration of Ions?
- Find out the electron configuration of the uncharged atom, then add or subtract the number of electrons gained or lost
-
Which one of these atoms is in the excited state?
1s2, 2s2, 2p5, 3s1
1s2, 2s2, 2p6
-
The .... levels of ..... and .... are quite similar. A consequence of this is that ................ will lose ... electrons before losing 3d
- The energy levels of 4s and 3d are quite similar. A consequence of this is that transition metals will lose 4s electrons before losing 3d
