The electron configuration of hydrogen is often written as 1s1. To understand the meaning of this, we must first understand what the term “electron configuration” means and how electrons are arranged in atoms.
Introduction to the Electron Configuration of Hydrogen
The electron configuration of hydrogen can be written as 1s1. This means that the single electron in the hydrogen atom is located in the 1s orbital. The 1s orbital is the lowest energy orbital in the hydrogen atom.

What is an electron configuration?
The electron configuration of an atom is a representation of the distribution of electrons around the nucleus. The electrons are arranged in shells, with each shell having a specific capacity. The first shell can hold up to two electrons, the second shell can hold up to eight electrons, and so on. The electron configuration of hydrogen is 1s1, which means that there is one electron in the first shell and no electrons in the higher shells.
Why is the electron configuration important?
The electron configuration of an atom is important because it helps to determine the atom’s chemical properties. The arrangement of electrons in an atom’s outermost energy level (its valence shell) determines how the atom will interact with other atoms and molecules. Atoms with similar valence electron configurations tend to have similar chemical properties.
How are electrons organized in an atom?
The electron configuration of hydrogen can be determined by looking at the periodic table. The first thing to notice is that there are only two elements in the first column. This means that there can be no more than two electrons in the first energy level. The next thing to notice is that hydrogen has an atomic number of 1. This means that it has one proton in its nucleus. Therefore, it must have one electron orbiting around the nucleus.
Writing the electron configuration for hydrogen
The electron configuration of hydrogen can be written as 1s1. This means that there is one electron in the first energy level, and that it is in the s orbital.
