Carbon 14 has a half-life of 5, 730 years. You begin with 600 grams of C-14. At the end of the first half-life, how much of the substance will turn to nitrogen?

5,730 years

Carbon-14 has a half-life of 5,730 ± 40 years—i.e., half the amount of the radioisotope present at any given time will undergo spontaneous disintegration during the succeeding 5,730 years.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
