Static Electricity Intro
I.
Static Electricity - electronic
charges flowing in no particular direction. (trapped in a body)
A) Electricity of the Atom
#p = #e-
n has no charge
p has +1 charge
e- has -1 charge
Charge
electron
1. Atoms become charged by gaining or losing ...
Electrons
Charge plates can deflect an electron
20 p , 18 e-
+ 2
Why are protons never lost or gained?
Protons are held in the nucleus by the strongest forces in the universe
a) Ion: electrically charged particle:
Charge is unbalanced
negative charge
#e > #p
positive charge
#p > #e
2. Charged
objects lose their charge when grounded. (become neutral)
When grounded:
Negatively charged objects ...
... lose electrons and become neutral.
Positively charged object ...
... gain electrons and to become neutral.
