Atomic Structure Flashcards
1
Q
In alpha particle model some deflected through large angles what does this mean?
A
Deflections through large angles show nucleus repels alpha particle.
Nucleus must be positively charged as charges repel.
Mass concentrated at centre of atom.
2
Q
Most alpha particles passed through with little or no deflection what does this mean?
A
Most of the atom is empty space
3
Q
How to calculate relative charge?
A
Overall charge proton-neutron=relative charge
