William Matthaeus, the Martin A. Pomerantz Chair of Physics and Astronomy at the University of Delaware, has won UD’s highest ...

In PCl5, phosphorous is surrounded by ten electrons. The compunds PF6- can also be created ... phosphorous has vacant 3d orbitals that can be used in bonding - 'expanded valence shell.' The exact ...

By twisting layers of graphene, researchers discovered a unique electronic crystal where electrons freeze in place yet allow ...

The photoelectric effect, first explained by Albert Einstein in 1905, laid the foundation for quantum mechanics. It occurs when high-energy light strikes atoms, releasing electrons. This phenomenon is ...

In the search for elusive particles called neutrinos, researchers are stringing thousands of detectors in the depths of the ...

We find that it is the 4s orbital electrons that are ionised first before the 3d orbitals. We have to conclude that, ironically for the d-block elements, the 4s orbitals are in fact higher in energy ...

In recent years, there have been attempts to describe the inside of a proton using quantum information tools, with partial ...

ASML’s strong moat is challenged by potential competitors and geopolitical risks. Read why ASML stock’s premium valuation may ...
