An artifact originally had 16 grams of​ carbon-14 present. the decay model upper a equals 16 e superscript negative 0.000121 ta=
xeze [42]

<u>Given:</u>

Initial amount of carbon, A₀ = 16 g

Decay model = 16exp(-0.000121t)

t = 90769076 years

<u>To determine:</u>

the amount of C-14 after 90769076 years

<u>Explanation:</u>

The radioactive decay model can be expressed as:

A = A₀exp(-kt)

where A = concentration of the radioactive species after time t

A₀ = initial concentration

k = decay constant

Based on the given data :

A = 16 * exp(-0.000121*90769076) = 16(0) = 0

Ans: Based on the decay model there will be no C-14 left after 90769076 years

Answer:

John Dalton

Explanation:

John Dalton in 1808 suggested that all matter consists of tiny particles called atoms and that the atoms of a specific element are identical.

He postulated the Dalton's atomic theory which has the following important parts;

  • All matters consists of indivisible particles called atoms
  • Atoms of the same element are similar and are different from atoms of other elements.
  • Atoms can neither be created nor destroyed.
  • Atoms combine in simple whole ratios to form compounds.
