y = a(1-r)^x
a is initial amount.
r is rate of decay.
x is the number of time intervals that have passed.
if you need more explanation, i want you to follow the related link.

Why do you think chemistry will not change the decay rate of an isotope?
It depends what is meant by 'decay'. It will not alter the atomic decay rate but elements can be chemically affected by the environment which can chemically decay them.
What is the decay rate of heart cells?
the decay rate of carbon is 14 in heart muscle cells,
As the temperature of a radioactive sample increases the rate of the nuclear decay?
It stays the same. Temperature has no effect on the rate of nuclear decay.
How the radioactive decay rate be changed?
The rate cannot be changed.
What is the nuclear decay equation for T99m?
T99 is Technetion 99 has a Decay rate of 6h

How do you calculate half-life?
Check the time between your first decay rate and when the decay rate reaches half this number. Half life T1/2 is calculated using the below formula T1/2=0.6931/r Where r is disintegration constant
What is the decay rate of heart cells?

What makes radioisotopes useful for dating objects?
They decay at a predictable rate.
Can paper decay?
Yes, but the rate of decay depends on the conditions.
As the temperature of a radioactive sample increases the rate of the nuclear decay?
It stays the same. Temperature has no effect on the rate of nuclear decay.
How the radioactive decay rate be changed?
The rate cannot be changed.
What two factors determine the rate of colonization of an island?
Decay rate and rate of regrowth
Decay always happens at the same rate in ecosystems?
decay always happens in ecosystems
What is the nuclear decay equation for T99m?
T99 is Technetion 99 has a Decay rate of 6h
Why would carbon dating work if carbon atoms did not decay at a constant rate?
Statistically carbon-14 atoms decay at a constant rate.
What is the effect of pressure on the rate of radioactive decay?
Pressure does not affect the rate of radioactive decay. That is entirely unaffected by the environment within the nucleus of the atom.
