Hydrogen Atoms in a sentence

For example, the empirical formula for glucose is CH 2 O (twice as many hydrogen atoms as carbon and oxygen), while its molecular formula is C 6 H 12 O 6 (12 hydrogen atoms, six carbon and oxygen atoms).

For example, a water molecule contains two hydrogen atoms, but does not contain atomic hydrogen (which would refer to isolated hydrogen atoms).

Further, a nuisance problem of ordinary hydrogen is its large incoherent neutron cross section, which is nil for D. The substitution of deuterium atoms for hydrogen atoms thus reduces scattering noise.

Muonic hydrogen atoms are much smaller than typical hydrogen atoms because the much larger mass of the muon gives it a much more localized ground-state wavefunction than is observed for the electron.

Nearly all deuterium found in nature was produced in the Big Bang 13.8 billion years ago, as the basic or primordial ratio of hydrogen-1 (protium) to deuterium (about 26 atoms of deuterium per million hydrogen atoms) has its origin from that time.

In aqueous solution both hydrogen and hydroxide ions are strongly solvated, with hydrogen bonds between oxygen and hydrogen atoms.

Thus amides can participate in hydrogen bonding with water and other protic solvents; the oxygen atom can accept hydrogen bonds from water and the N–H hydrogen atoms can donate H-bonds.

Each carbon of the double bond uses its three sp 2 hybrid orbitals to form sigma bonds to three atoms (the other carbon and two hydrogen atoms).

For example, ethane consists of two carbon atoms single-bonded to each other, with each carbon atom having three hydrogen atoms bonded to it.

For example, the empirical formula of ethanol may be written C 2 H 6 O because the molecules of ethanol all contain two carbon atoms, six hydrogen atoms, and one oxygen atom.

ISO-SWS observations find 22 atoms per million hydrogen atoms in Jupiter.

The hydrogen atoms on both the front and rear carbon atoms have an angle of 120° between them, resulting from the projection of the base of the tetrahedron onto a flat plane.

These OBBs are created by binding atoms of a transition metal (TM) to C 60 or C 48 B 12 and then binding many hydrogen atoms to this TM atom, dispersing them evenly throughout the inside of the organometallic buckyball.

The simplest form of an organic molecule is the hydrocarbon —a large family of organic molecules that are composed of hydrogen atoms bonded to a chain of carbon atoms.

Complementary neutron crystallography techniques are used to identify the positions of hydrogen atoms, since X-rays only interact very weakly with light elements such as hydrogen.

For example, hydrogen fluoride—which has three lone pairs on the F atom but only one H atom—can form only two bonds; ( ammonia has the opposite problem: three hydrogen atoms but only one lone pair).

However, many of the physical properties of water and ice are controlled by the formation of hydrogen bonds between adjacent oxygen and hydrogen atoms; while it is a weak bond, it is nonetheless critical in controlling the structure of both water and ice.

However, since hydrogen is necessary for the reactions listed above, the fuel selected must contain hydrogen atoms.

In addition to molecular hydrogen, the thermosphere-corona contains many free hydrogen atoms.

The symbol H is added if the atom in brackets is bonded to one or more hydrogen, followed by the number of hydrogen atoms (again one is omitted, for example: NH4 for ammonium ), then by the sign '+' for a positive charge or by '-' for a negative charge.
