What property of the elements determines the charge the
element's ions will have?

Metals lose electrons to form positively charged ions and nonmetallic elements gain electrons to form negatively charged ions.

if, i suppose that a bee stings me swinging my hand away from a bee. then that if, i persist patient when a bee or wasp areas on your surface to investigate a scent or to take h2o and i secreting heavily, the bug ultimately will move of its personal agreement. if i don't need to set for it to disappear, lightly and gently wipe it off with a part of the paper.
