how did j. j. thomson change the atomic model based on his experimental
results?

D- He described the atom as a sea of positive charge sprinkled with electrons

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
