◉How does the charge of one electron compare with the charge of
another electron? How does it compare with the charge of a proton?
Answer: Equal but opposite charges (+/- 1.60 x 10^-19 C)
◉What is most commonly the net charge of an atom? Answer: zero
◉What is a positive and negative ion? Answer: An ion is an atom or
group of atoms that has an electric charge. A cation is a positive ion
(protons > electrons), and an anion is a negative ion (electrons >
protons).
◉Electrostatics is a branch of electricity that focuses on Answer:
electrical charge
◉Name one particle that has exactly one quantum unit of charge.
Answer: An electron (or proton) has exactly one quantum unit of charge
, ◉The force that binds atoms together to form molecules is Answer:
electrical
◉The fundamental force underlying all chemical reactions is Answer:
electrical.
◉A fundamental rule of electricity is that Answer: like kinds of charges
repel and unlike kinds of charges attract
◉An electron and a proton Answer: attract each other
◉The vast numbers of electrons in a coin don't fly off the surface
because Answer: they are attracted by an equal number of protons
◉To say that electric charge is conserved means that no case has ever
been found where Answer: net charge has been created or destroyed
◉An electrically charged atom is an Answer: Ion
◉It is said that electric charge is conserved, which means that electric
charge Answer: can be neither created nor destroyed
◉To become a positive ion, an atom must Answer: lose an electron
