What is the name of the property of an atom with a positive charge? |
Proton |
|
|
What is the name of the property of an atom with a negative charge? |
Electron |
|
|
What is the name of the property of an atom with a neutral charge? |
Neutron |
|
|
How does an atom become neutral? |
It has the same number of protons as it does electrons. |
|
|
Explain the phrase, "opposites attract." |
Two things with opposite, or different charges (a positive and a negative) will attract, or pull towards each other. Things with the same charge (two positives or two negatives) will repel, or push away from each other. |

|
|
How does one determine the charge of an atom? |
Adding the number of protons and neutrons |
|
|
Solve the charge on the following situation:
+3 and -1 |
+2(positive) |
|
|
Solve the charge on the following situation: +1 and -1 |
0(neutral) |
|
|
Solve the charge on the following situation: +1 and -4 |
-3(negative) |
|
|
Solve the charge on the following situation: +4 and -1 |
+3(positive) |
|
|
How many electrons are contained in one coulomb of charge? |
6.25 ×1018 |
|
|
What is happening when two objects are rubbed together and static electricity results? |
When certain combinations of materials are rubbed together, the rubbing action transfer electrons from the atoms of one material to the atoms of the other. This imbalance of electrons leaves the former material with a positive charge and the latter with a negative charge. |
|
|
An inflated balloon is initiall uncharged. Then 3.2X10^6 C of negative charge is tranferred to the balloon. What might have happened during this process? |
2X10^13 electrons were added to the balloon. |
|
|
When negative charge is transferred to the balloon that is initially uncharged, what happens to the balloon? ( refer to where the charge goes and what happens to the balloon visually.) |
The charge distributes itself evenly over the surface of the balloon and the balloon expands. |
|
|
What is the equation of Coulomb's Force? |
F=(k*q1*q2)/r^2 |
|
|
Describe the equation of Coulomb's Force |
Force = Constant K *charge 1*charge 2 all divided over the square of the distance between them. |
|
|
Two charged objects are separated by some distance. The magnitude of the charge on the first object is greater than the magnitude of the chage on the second object. The two charges will exert forces on eachother that are WHAT in magnitude and WHAT in direction? |
EQUAL; OPPOSITE |
