Just these 3 in the pic quick asap i beggg yo

9) Their charges and separation.  (mass and separation is important for gravity)
10) loses electrons.  electrons have a negative charge so if a neutral atom gains an electron, now has a charge of -1.  If a neutral atom loses an electron, it now has a charge of +1.  (This concept is really important in ionic bonding and oxidation-reduction reactions)
11) wires.  Wires only provide electrons to a voltage source as well as a path way for the electrons to follow.  They do not actually cause the electrons to move.

I hope this helps.  Let me know in the comment if anything is unclear.

Ibelieve it's celsius. hope this .

The total number of electrons is 14
