Five years later, scientists were able to peer inside a hydrogen atom using a "quantum microscope," resulting in the first direct observation of electron orbitals.

You could swim through the deepest voids and encounter a single hydrogen atom in an entire football field's worth of space.

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 ...

In contrast, the 1HBrT, a different position of the H-atom facilitates easy and direct cleavage of the C–Br bond, allowing bromine to dissociate without interaction with the remaining triazole ...

The Shepley-Blair report, The Hydrogen Bomb, is now the center of a roaring controversy. The book has been denounced by men of weight, including many leading atomic scientists.

Explain to students that in a hydrogen atom, the negatively charged electron is attracted to the positively charged proton. This attraction is what holds the atom together. Tell students that hydrogen ...

Like ordinary water—H 2 0—each molecule of heavy water contains two hydrogen atoms and one oxygen atom. The difference, though, lies in the hydrogen atoms.

For example, the oxygen atom has eight electrons, the atom of iron has 26 electrons. Once Bohr tried to use his model to predict the spectral lines of more complex atoms, the results became ...
