What is an Atom video 1 Flashcards
Atom (2)
- The basic unit of matter
- The defining structure of elements
In an atom, you see…
The overall effect of the electron, not the proton or neutron but the net affect of the electron.
Neutrons has….. but no….
has mass
but no charge
If you give all three particles (electron, neutrons and protons) the same amount of kinetic energy….
electron will move way faster then neutrons/portions because it is lighter
Describe the position of electron and protons and neutrons (2 separate)
Protons+neutrons= Highly massive centre
Electrons has so much velocity its on the outside
AKA heavy stuff on inside
lighter stuff on outside
Structure of atom (3)
- Combination of subatomic particles with no net overall charge
- Fundamental rule: #of protons=#of electron
-In principle: any # of neutron is perfectly fine
Protons
The positively charged “core” of the nucleus
Neutrons (3)
The glue that allows protons to hang out together
*Because poise protons repulse each other, neutrons allow them to stay together in the nucleus
*The only thing that can change with the element staying the same *isotopes
Mass number
Number of proton plus number of neutron
Atomic number
Number of proton
An element is based on its…
number of proton
Atomic charge
Number of proton-Number of electron
Changing the amount of proton
Will cause a different element (Huge effect)
Changing the amount of neutron
Different isotopes (small effect)
Changing the amount of electron
Different ion (large effect)
