Static Electrical Force (SEf) = non-contact force
All matter is made up of zillions and zillions of ____ATOMS_____________. They are the smallest
particle that makes up everything on Earth. This is what it looks like…only much smaller.
Each atom is made up of 3 particles (parts):
1)
2)
3)
Protons- Have a _POSTIVE (+)_____ charge.
Electrons- Have a __NEGATIVE (-)___ charge.
Neutrons- Have a _NEUTRAL (N)___ charge.
*** What does neutral mean?_____________________
__NEITHER POSITIVE NOR NEGATIVE________________.
*** Protons and Neutrons make up the middle nucleus of the
atom while the electrons spin rapidly around the nucleus ***
If an atom has more protons than electrons, what charge do you think the atom will have?___(+)____
If an atom has more electrons than protons, what charge do you think the atom will have?___(-)_____
If the atom has an equal amount of protons and electrons, what charge do you think the atom will
have?____(N)_________
Are these atoms positive, negative or neutral?
6 e-, 4 p+, 5 N
3 e-, 4 p+, 5 N
2 e-, 2 p+, 2 N
Friction causes electrons to build up on atoms. When there is a buildup of electrons the atoms become
negatively charged. Together, the negatively charged electrons get rowdy and start to jump to different
positively charged atoms. When this movement of electrons occurs static electricity is formed.
Opposite charged atoms __ATTRACT_____ ___while like charged atoms __ REPEL_____________.
