What is meant by the term "positron"? | It refers to the nucleus and its having a positive charge |
Why does the nucleus have an overall positive charge? | Since protons have a positive charge and neutrons have no charge whatsoever. |
What is the overall charge of an atom? | neutral; the positive charges of the protons cancel out the negative charges of the electrons |
What are ions? | Positively/negatively charged substances which are no longer atoms because they are not neutral. They can be of multiple 2+, 3+, 4-, 2-, etc., or a single charge, 1+/1-. |
What is the difference between cations and anions? | cations - positively charged ions anions - negatively charged ions |
What is electrolysis? | The process (-sis) of electricity (electro-) breaking up (-ly-) ionic compounds by giving or taking away electrons from each ion. |
In electrolysis, what are the two electrodes? | The cathode and the anode |
What charges are the two electrodes in electrolysis? | Cathode - negative Anode - positive |
Where will cations and anions each go to during electrolysis? | Cations - to the cathode Anions - to the anode |
Why does each ion go to the electrode of converse (opposite) charge during electrolysis? | Because: - opposite charges attract - the electrons must be transferred from the negative charge to the positive charge to make both the ions and the electrodes neutral |
