Heavy rains suddenly pour down on a town that hasn’t had rain in months. Although the ground is dry, it can’t absorb the water fast enough. The high volume of runoff quickly becomes a problem and flash floods occur. Think about the different types of technology you just learned about. Which of them would be most helpful in preparing people for or reducing the damage of this weather event?

that tool would be a compass

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
