Q

conductors

A

materials that allow electrons to flow through them with ease
they cannot be easily charged by friction as extra electrons that are gained can easily escape

Q

static electricity

A

is an imbalance of electric charges on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge.

Q

positively charged atom
negatively charged atom
neutral atom

A

more protons then electrons
more electrons than protons
equal number of protons and electrons
all of this is the same for objects over just atoms instead of pro and electrons

Q

rules of charging

A

if there are two negatively charged objects they will repel each other
two positively charged will repel
one negative and one positive will attract
a neural and a charged will attract
