Subatomic Particles
Which particles are found in the nucleus of an atom?
Protons and Neutrons
Negative
As the distance increases (moves farther apart) how does that affect the force?
As distance increases, the force decreases.
Protons are negative.
False
Where are electrons found in the atom?
Electrons are located outside the nucleus.
What is the charge of a proton?
positive
How does decreasing charge affect force?
decreasing charge = decreasing froce
Electrons are found INSIDE the nucleus.
False.
What happens to the balloon when you rub it on the sweater (what is moving/what is transferring around) ?
Electrons are transferred from the sweater to the balloon when there is friction.
What happens to force if the charges are doubled (increased) ?
The force doubles (increases).
Use the unit convesion 1 m = 100cm. Convert 3.5 m into cm.
350 cm
Neutrons have no charge.
True.
When the balloon gains electrons from the water, explain how this transfer of charge causes the balloon and the sweater to each end up with an overall charge.
Gaining electrons = overall negative
Loosing electrons = overall positive
What happens to force if the distance is doubled (increased)?
The force gets 4x weaker.
Describe attractive forces.
When positive and negative charges are sticking together.
The closer together two objects are, the stronger the force between them.
True.
For an atom to be neutral, what must be true about the number of protons and electrons?
Protons = Electrons
What is the equation for calculating force ?
F = K x q1 x q2 / r2
Why does a charged balloon stick to a neutral wall (think polarization) ?
The electrons are shifting away, exposing the positive protons.
Like (or the same) charges pushing away from eachother is known as attraction.
False.
