Answer:
As its name implies, radioactivity is the act of emitting radiation spontaneously. This is done by an atomic nucleus that, for some reason, is unstable; it "wants" to give up some energy in order to shift to a more stable configuration.
Step-by-step explanation:
The X- intercept is (2,0) if you’re looking for one number then it would just be 2
Half of the starting amount remains after 1 half-life. So after 6 half-lives, the starting amount is halved 6 times, meaning that a 195 g sample would decay down to
(195 g)/2^6 = 195/64 g ≈ 3 g
