The image above represents the number of atoms present. To calculate the number of atoms present, three essential parameters are needed and these parameters are the Number of Atoms Present at t = 0 (No), Time (t) and Decay Constant (λ).
The formula for calculating number of atoms present:
N = Noe-λt
Where:
N = Number of Atoms Present
No = Number of Atoms Present at t = 0
t = Time
λ = Decay Constant
Let’s solve an example;
Find the number of atoms present when the number of atoms present at t=0 is 10, time is 5 and decay constant is 14.
This implies that;
No = Number of Atoms Present at t = 0 = 10
t = Time = 15
λ = Decay Constant = 14
N = Noe-λt
N = 10e-(14)(5)
So, N = 10e-(70)
N = 10e-70
N = 10(3.97e-31)
Then, N = 3.97e-30
Therefore, the number of atoms present is 3.97e-30.
