What is a charged particle called?
ion
100
Is metal a conductor or insulator?
conductor
100
What charge does lightning have?
negative
100
What are the 3 subatomic particles?
proton, neutron, and electron
100
What is the name of the piece of lab equipment that looks like a glass cup?
beaker
200
What is a positively charged ion called?
cation
200
Is glass a conductor or insulator?
insulator
200
What is happening to the particles in the cloud before lightning?
Cloud crystals are being ionized! Ice crystals collide with water droplets. Ice crystals lose an electron and become positively charged. Water droplets gain an electron and become negatively charged.
200
What charge does each of the subatomic particles have?
p=+1, n=0, e=-1
200
What happens when you change the number of protons in an atom?
Changing the number of protons in an atom will change the element.
300
What is a negatively charged ion called?
anion
300
Is salt water an insulator or conductor?
conductor
300
What is it called when the charges in the cloud separate (+ at top and - at bottom)
polarization
300
Where are each of the subatomic particles location?
p and n in nucleus, e in shells
300
What does a lightning rod do?
Since a lightning rod is made of metal, when struck by lightning, it conducts the electrons down to the ground to be 'ground.' This protects the building from being damaged.
400
What is the term used to describe a neutral object with separation of partial charges?
polarization
400
Why do conductors conduct electricity?
free electrons CAN flow
400
What is the lightning attracted to in the ground?
positive charges due to induced polarization
400
How do you know if an atom is neutral, at the sub-atomic level?
same number of protons and electrons
400
How does Coulomb's Law predict distance impacts force between two charged particles?
As distance increases, force decreases exponentially
500
What is the term used to describe the process of an atom losing or gaining an electron, changing its overall charge?
ionization
500
What happens to plastic during a lightning strike?
electrons vibrate in place and the plastic melts
500
What is happening to air particles during a lightning strike?
Ionization - electrons pass through air particles and create lightning branches, but only one reaches the ground and creates the large lightning bolt
500
Which subatomic particle can move, and why?
electron because small mass and in the shells
