What is the difference between an atom and an ion of the same element?
-
which one? 1.In ions, the number of protons and electrons are the same and there is no net charge. In atoms, the number of protons and electrons are different giving the atoms a charge. 2.In atoms, the number of protons and electrons are the same and there is no net charge. In ions, the number of protons and electrons are different giving the ion a charge. 3.There is no difference between an atom and an ion of the same element.

Answer:
2. It is the change in the number of electrons which dictates charge in ions of an element. The atomic number (protons) does not change.

the second option is correct. an atom has the same number of protons as electrons an ion is an atom that has lost or gained electrons. therefore the number of protons and electrons are not equal, giving the ion a positive or negative charge depending on whether it gained or lost electrons. a positive ion has lost electrons and a negative ion has gained electrons. this is because electrons are negatively charged
