Draw or take a screen shot picture from phet simulation to answer.
Why is atom 9 a positive cation? Were electrons gained or lost in order to form the ion?

How would you build a negative ion (anion) for atom 12? Would you need to lose or gain electrons?

A POSITIVE ION is called a ____________________ (cation, ion) and occurs when an atom ______________ (loses, gains) electrons. Choose the two correct terms to fill in blanks
A NEGATIVE ION is called a ____________________ (cation, ion) and occurs when an atom ______________ (loses, gains) electrons. Choose the two correct terms to fill in blanks
An ISOTOPE occurs when an element has a different ____________ (atomic number, mass number) because the number of _______________ (protons, neutrons, electrons) are different. Choose the two correct terms to fill in blanks
