An element has a half-life of 30 years. If you start with 10g of this element, how many grams of this element would remain after
drek231 [11]

After two half-lives or 60 years, 7.5 g of the element will be left.

<u>Explanation:</u>

<u>Half-life:</u>

  • In simple words, Half-life can be defined as the amount of time needed for a quantity to fall to half its value as contained at the beginning of the time period.

  • And after another sixty years (The two half-lives) 15 /2 = 7.5 g declines and 7.5 g remains disappeared.
