The race to build the first useful quantum computer is on and may revolutionize the world with brand new capabilities, from ...

An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...

Atoms are the basis of all the elements in the universe, the building blocks of all visible matter, and the secret to nuclear power. Skip to main content. Open menu Close menu.

If two atoms are brought close enough for long enough, then occasionally, completely randomly, the nuclei will find themselves intermingling. The result is nuclear fusion, where the two separate atoms ...

Atoms of the same element with different numbers of neutrons are called isotopes of that element. The atomic mass in the periodic table is an average of the atomic mass of the isotopes of an element.

The atoms of some elements like helium do not form bonds. Helium atoms are single atoms. The atoms of elements such as hydrogen, nitrogen and oxygen join in pairs to make molecules.

A new study lays the groundwork to expand the periodic table with a search for element 120, to be made by slamming electrically charged titanium atoms, or ions, into a californium target.

The team made two atoms of element 116, livermorium, during 22 days of operations at the lab's heavy-ion accelerator, the 88-Inch Cyclotron. Making an atom of element 120 would be even rarer, ...

Protons are tiny particles just a femtometer across, but without them, atoms wouldn't exist. Protons are tiny subatomic particles that, along with neutrons, form the nucleus of an atom. The ...

Dan Levitt’s book, “What’s Gotten Into You,” evokes a series of striking and often forceful images in tracing how our cells, elements, atoms and subatomic particles all found their way to ...

KS3 Chemistry Atoms, elements and compounds learning resources for adults, children, parents and teachers.

Atomic Number (Z)=Number of Protons. Example: Hydrogen: The simplest atom, hydrogen, has 1 proton in its nucleus. Therefore, the atomic number of hydrogen is 1. Carbon: Carbon atoms have 6 protons ...
