Sentences with phrase «electrons than protons»

Anion An anion from the Greek word???, meaning «up», is an ion with more electrons than protons, giving it a net negative charge (since electrons are negatively charged and protons are positively charged)» The opposite is a cation.

Flipping through your old chemistry notes, you'll recall that negative ions are atoms or molecules with more electrons than protons.

A tri-anion particle is a combination of atoms that contains three more electrons than protons.

Likewise, the ratio of electrons to protons can not vary by more than 1 part in 10 to the 37th power or else electromagnetic interactions would prevent chemical reactions.

Einstein wrote in 1920: «According to our present conceptions the elementary particles (that is, electrons and protons) are nothing else than condensations of the electromagnetic field....

Whether a stone or an electron being attracted to a proton is intrinsically less wonderful than the eye or the bacterial flagellum is less clear.

These are considerably stronger than covalent bonds, held together by multiples of: +1 charges (the same charge as a proton) and the -1 charge of an electron, creating a neutral formula.

That fact suggests that the particles must be more massive than about 0.3 billion electron volts — about a third the mass of a proton — the researchers calculate.

Because a proton or a neutron is on the order of a million times smaller than an atom, nuclear fission and fusion typically require energies on the order of millions of electron volts (MeV).

This huge machine, more than five miles in diameter, is capable of blasting protons together with a colossal energy of 14 trillion electron volts; it will be able to probe distances 1/10, 000 the size of a proton, perhaps creating a zoo of exotic particles not seen since the Big Bang.

These big bits of atoms, such as gold or silicon atoms stripped of their electrons, are much more complex than the protons that physicists have been accustomed to studying.

«The very idea of using protons rather than electrons to move charge encounters intuitive resistance,» says John Roberts, an electrical engineer at Cambridge University in the U.K. «People know how to control electrons.

Pluto has a thin, wispy atmosphere and probably lacks a magnetic field, so Krimigis isn't expecting to find much more than a few stray protons and electrons.

Why are protons 2,000 times heavier than electrons, yet their charges are simply equal and opposite?

By using electron and positron beams instead of heavier protons, the ILC will allow physicists to probe particle properties with much greater precision than they can at the LHC.

Slamming protons and antiprotons together at 40 tera - electron volts (40 trillion eV), the SSC would have put out more than enough energy to create the elusive Higgs boson, sometimes called the «God particle,» which gives other particles their mass.

Muons are about 200 times heavier than electrons, making them more sensitive to the proton's size.

Because the strong force holding the protons and neutrons together is stronger than the electromagnetic one, knocking the nucleus apart into pieces demands more energy than removing the electrons.

This shift is sensitive to the proton's radius, and muons — which some 200 times more massive than electrons — make it millions of times easier to measure.

The Alpha Magnetic Spectrometer has already cataloged more than 60 billion protons, electrons and other spaceborne subatomic particles, known as cosmic rays, as they zip by.

For the first time, RHIC is running at a record energy of 500 giga - electron volts (GeV) per collision, more than double the previous runs in which polarized proton beams collided at 200 GeV.

The improvement transformed a catalyst that created two or three oxygen molecules per second to one that produces more than 100 per second — with a corresponding increase in the production of protons and electrons that can be used to create hydrogen fuel.

While about 1,000 times less dense at Pluto's orbit than at Earth's, solar winds carrying protons and electrons, as well as ionized helium and oxygen, gust outward at about 300 to 500 km / s (187 to 311 miles / s).

We've long known that the basic constituents of nature are far more numerous and varied than the protons, neutrons and electrons that many people first learned about in high school.

Once an atom has fewer electrons, with a negative electrical charge, than protons, with a positive electrical charge, this atom now has more positive electrical charge than negative electrical charge - we therefore say that this atom is, itself, positively charged.

Across the continent, people were lining up by the millions on one side or the other of a new binary system, being told they were «positive» or «negative» as if they had turned overnight into protons and electrons and everyone spoke of subatomic physics, rather than of who was going to live and who was going to be shunned, endure terrible suffering, and die.
