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.Know More
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 element holmium contains 67 protons. In its elemental state with a neutral charge, an atom of holmium, which is represented by the chemical symbol Ho, contains an equal number of protons and electrons along with 98 neutrons when it's in its most stable form.Full Answer >
A neutral atom containing 12 protons is of the element magnesium. If the atom had a positive or negative charge, it would still be of the element magnesium; however, it would then be classified as an ion.Full Answer >
The element with 82 protons is lead. Lead also has 82 as an atomic number and 82 electrons. The number of protons is equal to the number of electrons in a neutral atom.Full Answer >
