Easily calculate Ionization Energy with our simple Ionization Energy Calculator. Just enter the atomic number to get instant results in eV, kJ/mol, or kcal/mol.
Ever wondered how much energy it takes to pull an electron out of an atom? That’s what ionization energy tells you. Our Ionization Energy Calculator makes this process quick and simple. You don’t need to be a physicist to use it just enter the atomic number, and you’ll get the result in seconds. This calculator is based on Bohr’s Theory of the Hydrogen Atom, so it’s scientifically accurate yet easy enough for anyone to understand.
Ionization energy is the amount of energy needed to remove one electron from an atom. In simple terms, it’s how tightly an atom holds onto its electrons. The higher the atomic number, the more energy you’ll need to remove one.
For example, Hydrogen (Z = 1) has a smaller ionization energy compared to Silicon (Z = 14) because Silicon’s nucleus holds electrons more strongly.
The formula used in our calculator is:
Ei = √Z × 13.6
Where:
Ei = Ionization Energy (in electron volts, eV)
Z = Atomic Number
This formula comes from Bohr’s theory of the hydrogen atom. It shows that ionization energy depends on the square root of the atomic number multiplied by 13.6 eV.
Example:
If Z = 14 (Silicon), then
Ei = √14 × 13.6 = 50.88 eV
So, Silicon’s ionization energy is about 50.88 eV.
Using the calculator is as easy as flipping a switch.
The calculator will show you:
That’s it! You’ll get the answer instantly.
You don’t need complex equations or lengthy textbooks. Our Ionization Energy Calculator is fast, accurate, and free. It’s designed for students, researchers, and anyone curious about atomic energy. Whether you’re doing homework or working on a chemistry project, you’ll find this tool incredibly handy.
Let’s take Oxygen (Z = 8) as an example.
Ei = √8 × 13.6
Ei = 2.83 × 13.6
Ei = 38.49 eV
That means you’ll need 38.49 electron volts of energy to remove one electron from an oxygen atom.
If you want it in kJ/mol, the calculator will automatically convert it for you:
38.49 × 96.485 = 3715.47 kJ/mol
Our Ionization Energy Calculator makes tough physics simple. With it, you can instantly find how much energy an atom needs to lose an electron. No math stress, no confusion just fast and accurate results.
Whether you’re studying chemistry, teaching, or just curious, this calculator gives you a clear and quick way to understand atomic behavior. Try it once, and you’ll see how easy science can be!
It supports eV (electron volts), kJ/mol, and kcal/mol.
It’s based on Bohr’s Theory of the Hydrogen Atom, which provides a reliable approximation for most atomic calculations.
Yes. You can calculate for any element with an atomic number from 1 to 118.
Ionization Energy measures how much energy it takes to remove an electron, while Binding Energy measures how much energy holds the nucleus together.
