Ununoctium, with 118 protons, has the highest number of protons, but uranium has the most protons of any naturally occurring element with 92. However, ununoctium is a manmade element, as it isn't possible for it to exist in nature.Continue Reading
Uranium is the heaviest natural element. In addition to ununoctium, which was first discovered by a team of Russian chemists in 2006, there are 25 other manmade elements that have more protons and are heavier than uranium.
The discovery of ununoctium was made through the collision of light particles, which resulted in an atom of ununoctium that lasted for less than one-thousandth of a second before breaking apart.Learn more about Atoms & Molecules
The number of protons an atom has depends on what element it is. A hydrogen atom, for example, only has one proton. A nitrogen atom has 7 protons, an atom of antimony has 51 protons and an atom of radium has 88 protons.Full Answer >
To find the number of electrons an element has, locate it on the periodic table of elements, find the atomic number, and note the number of protons; because atoms are naturally electrically neutral, the protons and electrons are usually equal. Look at the oxidation number for further information.Full Answer >
The main distinguishing factor between the various chemical elements is the number of protons in an element's nucleus, which is known as the element's atomic number. The atomic number also corresponds to the number of electrons the element has because elements have equal numbers of protons and electrons.Full Answer >
Isotopes of the same element have the same number of protons and electrons when in neutral atomic form. Different isotopes have different numbers of neutrons in their nuclei, resulting in different atomic weights for the different isotopes of a single element.Full Answer >
