Electrostatics are the charged parts of an atom

Electrostatics

____ are the charged parts of an atom. a. Only electrons b. Only protons c. Neutrons only d. Electrons and neutrons e. Electrons and protons f. Protons and neutrons

TRUE or FALSE: An object that is positively charged contains all protons and no electrons.

TRUE or FALSE: An object that is negatively charged could contain only electrons with no accompanying protons.

True or False: Since the proton is much more massive than the mass of an electron, the magnitude of its charge is also significantly greater.

Identify the following particles as being charged or uncharged. If charged, indicate whether they are charged positively or negatively. (n = neutron, p = proton, e = electron)

Consider the graphic below of a neutral oxygen atom. a. Explain what must happen in order for the oxygen atom to become negatively charged. b. Explain what must happen in order for the oxygen atom to become positively charged.

Determine the quantity and type of charge on an object 12 that has 3. 62 x 10 more protons than electrons. • Answer: +5. 8 x 10 -7 Coulombs • To determine the charge on an object, determine the number of excess protons or excess electrons. Multiply the excess by the charge of an electron or the charge of a proton - 1. 6 x 10 -19 C. Finally, adjust the sign of the object to + or -.
