# If hydrogen has one electron then what is the need of electron to go on higher orbitals?

If hydrogen has one [electron](https://answers.mindstick.com/qa/49055/what-year-was-microscope-electron-invented-and-how) then what is the need of electron to go on higher orbitals?

The **hydrogen atom** which has **one electron in its lowermost orbit** then it needs the required **amount of energy** to go in the higher state or the stable state. **That energy is known as orbital energy.** ![If hydrogen has one electron then what is the need of electron to go on higher orbitals?](https://answers.mindstick.com/questionanswer/6ba7cd30-6344-4982-a7e2-ad845f52cc3c/images/cc69a97b-1c14-41e5-9d80-a8e634bbaec3.png)\

**Hydrogen** In the periodic table, this is the **first member** and has the **lowest atomic number** which is **1,** and the symbol representation is **‘H’**. This is the **lightest element** in the periodic table and the standard situation, this is in the form of a**[Diatomic molecule](https://www.britannica.com/science/diatomic-molecule)** which is known as the **Hydrogen gas** having the formula of **H2**. This gas is the most abundant in the universe and it contains about **75%** of all the normal matter. \
The **energy in the lowest state of the atom is -13.6 eV**. The energy level of Hydrogen can be easily calculated with the help of the **[Bhor model](http://hyperphysics.phy-astr.gsu.edu/hbase/Bohr.html)** of the atom. This model explains that the **electrons** and **protons** of the atom are bounded by the **electromotive force** while in the solar system, all the planets revolve around the Sun due to the reason of the presence of **Gravity.** \
The most accurate description of the energy of the **hydrogen** can be seen in the **Schrodinger Equation** with the help of **quantum mechanics.** The electrons of the ground state of the Hydrogen have no momentum. \
**Orbitals energy in the Hydrogen atom** As we saw in the **electronic configuration section**, we see that there are many different energy sections. The lowest energy state has of an atom has its electrons filling orbitals which can have **two electrons in the ground state to achieve the stable state.\** \
When the energy is added to the g**round state orbital** an electron can go to the one higher stable state of energy orbital. There is a fact which is very necessary for it. and that **the same energy should be added** as the energy occupied by the higher state and the lower state and the **difference between both is the requirement in the energy.** \
