A
Neils Bohr nb 3
3
Q
- Electron cloud model
A
Schrodinger and heisenburg nb 3
4
Q
- In each period how does the number of electrons in each kind of atom change from left to right between group 1 and group 2
A
of electrons increases by 1 in a period as moves across the period nb 15
5
Q
- An isotope has 7 neutrons - is this the most common form of the isotope?
A
No b/c avg atomic mass on the PT is 12.011 and is weighted average - 12C is most common nb12
6
Q
- Describe one similarity and one difference between the two atoms you drew above. Include why they are expected based on the elements location on the PT
A
Same # of valence electrons so same Group
Different # of energy levels so different periods nb14
