The total number of protons and neutrons in an atom is called the mass number. You can find the mass numberfor any element. The mass number canbe found by rounding the average atomic mass to the nearest whole number.
as an example
6.25 is closer to 6 than 7 so it is 6
6. 50 is closer to 7 so it is 7
you have to look at the thenth digit. if the number is 4 or less you have to round it down
if the tenth digit is 5 or greather than you have to round it up.
It is not sodium. If you drop hot molten sodium into water it flashes and violently reacts with water but does not quite explode like the molten sodium chloride. It most likely is not ... If you check the PH afterexplosion, water is still neutral PH.
BUT because sodium chloride is table salt. your answer is false!
