Charges of the nucleus, atom, ions and more

Frage	Antworten
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
