How does radioactive dating allow scientist to accurately date rocks

Radioactive dating allow us to accurately date rocks  by measuring the quantity of unstable atoms left in a rock and comparing it to the quantity of stable daughter atoms in the rock

Explanation: See, radioactive atoms are unstable. They continuously decay to form stable daughter atoms. When molten rock cools, radioactive atoms are trapped inside. Afterwards, they decay at a predictable rate. By measuring the quantity of unstable atoms left in a rock and comparing it to the quantity of stable daughter atoms in the rock, scientists can estimate the amount of time that has passed since that rock formed.

Some atoms used for radioactive dating are that of carbon, uranium, potassium, etc.,

Sedimentary rocks can be dated using radioactive carbon, but because carbon decays relatively quickly, this only works for rocks younger than about 50 thousand years.

Igneous rocks can be dated using elements that are slow to decay, such as uranium and potassium
