One mole contains the same number of particles as there are atoms in 12 g of carbon-12. As atoms and molecules are so small, the number of particles in a mole is very large. This number is: ...

A new kind of quantum computer uses a high-resolution microscope to control the electron spins of titanium atoms. Plus, the Universe-mapping Euclid telescope fixes the wobble that threatened its ...

The chemical formula of a covalent molecular substance gives the number of atoms per molecule. The formula of a covalent network or ionic compound gives the simplest ratio of atoms/ions in the ...

WEST LAFAYETTE, Ind. — Matter gets weird at the quantum scale, and among the oddities is the Efimov effect, a state in which the attractive forces between three or more atoms bind them together, even ...

How many atoms are there in a kilogram of silicon? This number is Avogadro’s constant and working out its value is one of the more important tasks that materials scientists face. Today, a group of ...
