Q

How can an object become charged?

A

An object becomes charged by friction, for example a balloon is rubbed on wool, now the wall is + and the balloon -
is gaining or losing electrons

Q

If electrons are not found in the nucleus where are they located?

A

They orbit around the nucleus

32
Q

Explain why most objects are considered electrically balanced.

A

They are electrically balanced because they have the same number of electrons and protons

33
Q

If an object loses electrons when it is rubbed, it is said to have a _________ charge because it has more protons

A

Positive

34

If an object is rubbed and it loses electrons, what kind of charge will it have?

A

Positive

48
Q

Explain why the object that is rubbed and loses electrons will have a positive charge?
