Ionization occurs at energies greater than 5 × 10–19 j. is there a risk of exposure to ionizing radiation if a radar speed gun is pointed at a person instead of a car?

h let me think

we need the questions , i may then you.

answer; talc and gypsum;

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: )
