If an ion has 13 protons and 10 electrons what is the charge on the ion?

Al3+ indicates an ion of aluminum having a charge of + 3. I.e., since an aluminum atom normally has 13 protons and 13 electrons, this ion has 10 electrons (-10 charge) and 13 protons (+ 13 charge) giving it a charge of + 3 (-10 + 13 = +3).

Explanation:

they begin to vibrate harder causing the material that was solid to turn into a liquid i.e gallium or ice

for points guys
