If you blew up a balloon inside an air-conditioned house and then brought it outside on a hot summer day, then what do you expect to happen to the balloon?

You can expect the balloon to expand a little

Explanation:

The molecules in the balloon will be heated up once they feel the warmth of the summer heat and start moving a lot faster

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
