A radioactive isotope decays. Both the parent atom and daughter atom look the same, but the daughter is more chemically stable. What type of decay occurred?

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

She should use 12/3 to measure
