An atom that has an equal number of protons and electrons is:
positively charged
negatively charged
neutral
An atom that has more protons than electrons is:
positively charged
negatively charged
neutral
An atom that has fewer protons than electrons is:
positively charged
negatively charged
neutral
In real life, which is more likely to have caused a neutral atom to get a charge of +1?
A proton was added.
An electron was removed.
Either process equally likely to have happened.
In real life, which is more likely to have caused a neutral atom to get a charge of -1?
A proton was removed.
An electron was added.
Either process equally likely to have happened.
How could you change the overall charge of an atom without changing the atom’s element?
Change the number of protons
Change the number of electrons
Change the number of neutrons

mass number
atomic number
average atomic mass
number of protons
The mass number of an atom =
protons + neutrons
