All ions are atoms with a (2 points)
positive charge.
negative charge.
charge.
neutral charge.

That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number. Ions are atoms with extra electrons or missing electrons. When you are missing an electron or two, you have a positive charge. When you have an extra electron or two, you have a negative charge

SO THE ANSWER WOULD BE CHARGE. -- C

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
