Many heavy atoms form from a supernova explosion, the remnants of which are shown in this image. NASA/ESA/Hubble Heritage ...

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

Explain to students that the two electrons in the bond between the hydrogen atom and the oxygen atom can be thought of as “belonging” to each atom. This gives each hydrogen atom two electrons in its ...

Such combining of experiments with quantum chemistry shows that hydrogen position change has a direct influence on the molecular dynamics after an interaction with low-energy electrons, where even ...

X-ray-excited electrons are then tunneled to the detector tip (gray) via overlapping atomic/molecular orbitals, which provide elemental and chemical information of the iron atom. Credit: Saw-Wai Hla ...

Hydrogen is a promising energy source for next-generation technologies, but storing and transporting it is expensive and challenging. Now, researchers from Kyushu University have developed an ...

A Toyota Mirai hydrogen fuel-cell vehicle. (Patrick T. Fallon/Bloomberg News) On Monday night in Atlanta, Donald Trump described a made-up scenario in which GOP Rep. Marjorie Taylor Greene of ...

But apart from hydrogen, all other atoms in the periodic table have more, some many more, electrons orbiting their nuclei. For example, the oxygen atom has eight electrons, the atom of iron has 26 ...

The number of protons in an atom of any given element is always the same. Physicists call this the atomic number.So, in the above example of lead, its atomic number is 82 and that does not change ...

Hydrogen atoms and an oxygen atom are close together. Electrons from each atom feel the attraction from the protons in the nucleus of the other atom. This attraction pulls the atoms together and the ...

The position of hydrogen atoms in bromine-substituted triazoles critically determines their molecular dissociation pathways when exposed to low-energy electrons. Subtle shifts in hydrogen location ...
