"Oxygen atoms" refers to individual particles that make up the element oxygen.
Oxygen atoms are the building blocks of oxygen gas and are crucial for supporting life and combustion.
Full definition
The next
oxygen atom in moves just far enough away to get electrons from untouched atoms.
That's because sequential rings
of oxygen atoms exactly match the size, and balance the charge, of potassium ions.
When the platinum nanoparticles catch molecules from the surrounding gas and combine them
with oxygen atoms from the iron - oxide surface, a surplus of iron atoms remains.
Free radicals are
oxygen atoms which can badly damage cell structures leading to lowered immune response and vulnerability to numerous degenerative diseases.
Instead,
oxygen atoms pull in a bit of the negative charge from the nearest uranium atoms, from the next nearest, and from the next - next nearest.
At the atomic level, in the many batteries that use lithium - nickel - manganese oxide, the manganese and
oxygen atoms form orderly rows.
These tiny clusters would
add oxygen atoms more efficiently than larger clusters.
But any closer investigation of ice and its remarkable properties has to start with water molecules — each with one
oxygen atom joined to two hydrogen atoms.
For combustion 2.3 times as
many oxygen atoms are pressed into the turbo engine than a naturally aspirated engine.
When an electrically excited
free oxygen atom encounters an oxygen molecule, they may bond to form ozone.
One is to measure the ratio of heavy and
light oxygen atoms in the ice and the other is to measure the ratios of heavy and light hydrogen.
For example, in water (H2O) the
sole oxygen atom is bound to two hydrogen atoms, and the two bonds constantly change in length.
Specifically, inserting two
consecutive oxygen atoms into a substance brings health benefits in drugs that fight disease.
Now, if one
oxygen atom lets go of the carbon atom next to it, the three atoms would align in a row.
Four different materials formed depending on the concentration
of oxygen atoms.
Researchers placed four different carbon - ring molecules
with oxygen atoms for «legs» on a copper surface.
The blue
represents oxygen atoms, the red ions of oxygen, the green sulfur, and the orange stray remnants of the star, mostly hydrogen.
POMs are molecular transition metal - oxygen clusters in which the metal atoms are bridged
by oxygen atoms to form a three - dimensional network.
The commonly accepted mechanism for direct synthesis of H2O2 essentially states that hydrogen and
oxygen atoms bind adjacent to one another on the catalyst surface and then react, Wilson said.
The red - tinged spikes at the top of the loop are produced by ionized
oxygen atoms at higher altitudes, up to 500 km (300 miles).
The Boulder technique employs a towering array of mirrors focused on a single point to heat a metal oxide reactor to 1,350 ° Celsius (or 2,462 º Fahrenheit, about the melting point of carbon steel) and set up a chain of atomic - scale events which grabs
oxygen atoms from steam, releasing the hydrogen molecules.
The net result of all this punishment is, as Taylor puts it, an «unhappy» surface,
where oxygen atoms in the rocks regularly break their chemical bonds.
Water molecules are made up of one negatively
charged oxygen atom and two positively charged hydrogen atoms.
The researchers let the needle scent α - pinene react with both «normal» ozone (16O3) and «labeled,» heavier ozone (18O3), in order to determine the portion of
heavy oxygen atoms (18O) in the formed ELVOCs.
The iodine's cationic behavior strongly attracts the negative
oxygen atoms on three nearby water molecules.
(The unusual form of hydrogen let scientists correct results
for oxygen atoms lost in H2O, for instance when the bear urinated.)
The mostly greenish blue emission is from
ionized oxygen atoms at an altitude of 100 — 250 km (60 — 150 miles).
Water molecules are shown as blue spheres, the four manganese atoms in purple, the calcium in green and the
bridging oxygen atoms in red.
The models showed that thinner carbon nanotubes with a relatively high concentration of nitrogen would perform best,
as oxygen atoms readily bond to the carbon atom nearest the nitrogen.
Under high pressures, the variety of possible ice structures shrinks, just as the space between its hydrogen - bonded
oxygen atoms does as the ice grows denser.
Much like the way tea flowing through a leaky mug pools under a tablecloth, so
oxygen atoms flow out of a tiny cluster to pool under an extremely thin carbon sheet.
In its stratosphere I conclude the important photodissociation reaction that of carbon dioxide with ultraviolet photons which
produces oxygen atoms and carbon monoxide molecules.
Scientists at the Department of Energy's Oak Ridge National Laboratory have developed a new oxygen «sponge» that can easily absorb or
shed oxygen atoms at low temperatures.
This material, in which carbon substitutes for some of the
lattice oxygen atoms, absorbs light at wavelengths below 535 nanometers and has a lower band - gap energy than rutile (2.32 versus 3.00 electron volts).
The world's most commonly used radioactive substance — and its heaviest natural element — clutches its two
oxygen atoms so tightly, it almost never reacts with other compounds.
When the action of plate tectonics draws water - containing minerals down deep enough to meet the Earth's iron core, the extreme conditions cause the iron to
grab oxygen atoms from the water molecules and set the hydrogen atoms free.
While iodate is huge and surrounded by
negative oxygen atoms, its central iodine atom takes on a positive character, or becomes a cation.
aldehydes A family of chemical compounds that contain a «carbonyl group,» which is a carbon and
oxygen atom linked chemically with a double bond.
