Electric charge

12 p+

Atoms are neutral

Same # of protons as electrons

Electric charge

12 p+

Overall charge +2

When electrons are gained or lost, atom has an overall charge (net electric charge)

Are we alike?

• You are made of atoms which have protons and electrons

• Electrons move through you easily

What holds/transfers charge?

Electrons easily move through conductorsconductors

Electrons do not easily move through insulators insulators

(BUT insulators can still become charged)

Page 7: STATIC ELECTRICITY Electric charge 12 p+ Atoms are neutral Same # of protons as electrons.

Three ways to transfer charge:

Charge by frictionfriction

Charge by inductioninduction

Charge by contactcontact

Page 8: STATIC ELECTRICITY Electric charge 12 p+ Atoms are neutral Same # of protons as electrons.

FRICTION:

Charge by frictionfriction

Law of Conservation Charge Rubbing does not create charge, it merely transfers charge.

CONTACT

Charge by contact

Law of Conservation Charge Both objects end up with the same type of charge (but now have less of it).

Page 10: STATIC ELECTRICITY Electric charge 12 p+ Atoms are neutral Same # of protons as electrons.

INDUCTION

Charge by inductioninduction

PHET animation

Law of Conservation Charge Induction separates charge in the object, but the number of protons and electrons remains the same (assuming the object was initially neutral).

Atomic number = # of protons = # of electrons (neutral atom)

Atomic number = # of protons = # of electrons (neutral atom)
