An object that is positively charged contains all protons and no electrons.

TRUE

FALSE

10.

Negatively charged objects have protons; it's just their number of electrons is greater than their number of protons.

TRUE

FALSE

11.

Electrically neutral atoms simply possess the same number of electrons as protons. This gives the objects a balance of both type of charge.

TRUE

FALSE
