Half Life Definition

As per the half life definition, The total time required by any substance or quantity to get abridged to half of its initial concentration is called half life.

Introduction to Half Life Calculator

Half life is explained as the time required for the decay rate of any substance that might be having an unstable structure by a constant factor 2. Hence, if the initial concentration of a particular sample is known as A then, the decay in this amount after half life will be A/2.

Half life calculator is an online way to calculate half life online. The half life formula calculator is an efficient tool which saves you a lot of time doing manual calculations.

Half Life Formula

Half life is based around the decay process and the number of unstable nuclei remaining after time "t". Mean half life calculator uses the half life formula to compute results. So the value of "t" can be found or determined using half life equation

$$\text{N(t)} = \text{N(0)}\;*\;0.5\frac{t}{n}$$

Where:

• N(t) is the remaining quantity of a substance after time "t" has elapsed
• N(0) is the initial quantity of this substance
• T is the half life

You can also determine the remaining quantity of a substance using some other parameters in the given formula like:

$$N(t) = N(0)\;*\;e^{(\frac{-t}{τ})}$$

$$N(t) = N(0)\;*\;e^{(-λt)}$$

Where:

• "τ" is the mean lifetime - the average amount of time a nucleus remains intact
• "λ" is the decay constant (rate of decay)

Every one of the three parameters portraying a substance's radioactivity is connected in an accompanying manner:

$$T=\frac{ln(2)}{λ} = ln (2)*τ$$

Half life equation calculator help you finding results without any delays. If balancing equation is a difficult task for you, you can use equation balancer for your balancing your equations online.

How to find Half Life?

There are 2 ways through which we find half life. The digital method includes the usage of half life equation calculator. And the other is manual way.The time period is associated with half-life, let's say 7 days means that if you have a considerable number of radioactive atoms with that half-life, then after 7 days, half of them have released their excess energy and decayed into something else.

So if we have 10,000 atoms of Exampelonium-111 with a half-life of 7 days we would only have 5,000 atoms of it. Then 7 days later, we would only have 2,500 atoms, etc. A half life calculator with steps helps you to find the exact time at which a radioactive element need to decay to its half.

What is Radioactivity?

Radioactivity is a phenomenon that occurs in nature as well as in labs where it is done artificially. In this process, the nucleus of atoms disintegrates by emitting waves of energy called radiation.

How does Radioactivity works?

The atoms of heavier elements do not have an ideal proton to neutron ratio. This makes them unstable. In order to approach the stable ratio, the atoms go through radioactive decay and in the process emit energy or various particles as by-products.

The most common types of materials showing radioactive decay are Uranium, Strontium, Plutonium and Radium. The reason for the instability in these and other radioactive materials is that they have extra neutrons in their atoms. This creates imbalance.

Types of Radioactive Half Life Decay

Radioactive half life decay is of three types

• Alpha Decay
• Beta Decay
• Gamma Decay

How to use Half Life Calculator?

Half life calculator grams uses half life formula to solve half life equation & half life problems. You'll need to follow below steps to calculate the half life of any radioactive element using online half life calculator chemistry.

• Enter the initial or beginning amount of a substance in the first field.
• Enter the final amount of an element in the second field.
• Enter the elapsed time (how long it took for that amount to the material to decay) in the third field.
• Now click on the "CALCULATE" Button.

After putting all the values in the mean half life calculator with steps, it will compute a result for you without any delaying. You can confirm the results by manually solving half life equation using half life formula.
