A hydrogen atom has one electron. The hydrogen atom is simply made up of one electron and one proton that are bound together by an electromagnetic force.Know More
In order for a hydrogen atom to exist, it must have both an electron and a proton. The electron has a negative charge and the proton has a positive charge, and these charges work against each other to make the electromagnetic force that holds the entire atom together. They are constantly working against each other because one is positive and one is negative, but their repulsion is what makes the hydrogen atom exist. Occasionally, the electron will escape from the proton and the hydrogen will then become a positively charged ion. The hydrogen atom is capable of locating a new electron when this happens.
In the past, it was not uncommon for hydrogen atoms to be shown as a very large proton with a very small electron sitting on the edge of the atom. While this was easy for people to visualize, it was not an accurate representation. The proton is much stronger than the electron, but it is not necessarily bigger than it. The electron is now shown as a force that encapsulates the entire atom and makes up the majority of the atom, instead of being a simple speck sitting on the edge of the atom.Learn more about Atoms & Molecules
Hydrogen has one valence electron because it is an element found in group 1 of the periodic table. It is a simple task to find the number of valence electrons from the periodic table by looking at the group number found above each column. Similarly, the electrons found in an atom's outer shell are called valence electrons.Full Answer >
Hydrogen has one electron. Its electron configuration is 1s1.Full Answer >
An electron is a negatively charged sub-atomic particle that is located in an atom along with protons and neutrons. The electrons are found in shells and sub-orbitals that surround the nucleus of the atom.Full Answer >
A valence electron is a type of electron present in an atom that works to aid in the process of chemical bond formation with other atoms. These electrons are present in the outer shell of an atom.Full Answer >
