How do you know which objects get positively charged and which objects get negatively charged?

For this we take a test charge which is a unit positive charge.
Now, we take charge to be tested and bring test charge near to it. If both the charges repel the charge taken is positive and it they attract then the charge taken is negetive.

What forms when atoms lose or gain electrons and become positively or negatively charged they are know as?
The atom becomes an ion. Also, A positively charged atom is called a Proton A Negatively charged atom is called a Electron
How did Thompson know atoms were neutrally charged?
Early scientists have discovered the negatively charged particles and the positively charged. The atom is neutral because of the presence of equal amounts of both the charges which cancel each other
What happens when a balloon with a negative charge is brought to the surface of a wall?
i dont know ask your friends at school. if your old, live with it. A Negative Charge or a collection of negative charges will repel other negative charges. A negatively charged balloon will therefore repel those few negative charges in a wall that are capable of moving a little bit. That area of the wall close to the negatively charged balloon will therefore become positively charged. A positively charged wall will attract a negatively charged balloon and the two will stick together.
How did Rutherford know that nucleus was positively charged?
the nucleus is positively charged because it bounces right off of the gold foil
Do positively charged DNA molecules flow to the negatively charged poles in the electrophoresis chamber?
Yes. Positive(+) goes to negative(-). During gel electrophoresis, the positively charged molecules move to the negative cathode, and vis versa the negatively charged molecules move towards the positive anode.
1 How do you know that two substances get different charges when they are rubbed together?
You can use the electrostatic series to determine charge by looking at the substances higher on the list will always lose electrons and becomes positively charged and the substances lower on the list always gains electrons and becomes negatively charged
Why is an atom negatively charged and has a high density?
i dont know. sorry
The negatively charged particle that rotates the nucleus of an atom is know as?
An electron.
Are electrons negatively charged?
It is merely a sign convention. Electron does not have negative charge. We just know that there are two types of charges in nature. Opposite charges attract and like charges repel. We arbitrarily assume electron to have a charge called "negative". It would have been as well if we would have called charge on electron as "A" and charge on proton as "B". So its just an assumed name.
How did Watson and Crick affect society negatively or positively?
They affected it positively, because we wouldn't know what we know today! We wouldn't know that DNA is like a spiral staircase and how it works with the complementary base pairs.
Substances that dissolve in water?
substances that dissolve in water include, sugar, salt and others.
How did JJ Thomson know that the particles in the cathode-ray tube were negatively charged?
They are found to be deflected by electric and magnetic field in the specific direction in which a negatively charged particle would get deflected.
