WebAug 27, 2024 · 241 Am 95 → Z X A + 4 He 2 A = number of protons = 95 - 2 = 93 X = the element with atomic number = 93 According to the periodic table, X = neptunium or Np. The mass number is reduced by 4. Z = 241 - 4 = 237 Substitute these values into the reaction: 241 Am 95 → 237 Np 93 + 4 He 2 WebHalf-life is defined as the amount of time it takes a given quantity to decrease to half of its initial value. The term is most commonly used in relation to atoms undergoing radioactive … WebSolution: 1. Since the half life of Carbon 14 is 5730 years, this means that after 5730 years there will only be 5 micrograms of Carbon 14 left in the preserved plant: To solve for , notice that is in the exponent and so we need to take a logarithm to isolate . Since the base of the exponent is , the natural logarithm is appropriate. neighbourhood administrative system
