Atoms with 1 or 2 electrons on their valence level tend to gain?
more electrons because all atoms want to be like noble gases and will either give or take electrons to obtain 8 electrons so atoms with either 1 or 2 electrons would wither give off 1 or 2 electrons depending on how many then had
How ions knock off electrons from atoms?
You hammer the electrons to make it fall down!
Why do you keep giving electric shocks to people who you touch?
When you move in dry areas you knock off electrons and change your charge. If you knock off electrons then you go positive. If you gain electrons you go negative. When you touch something or someone that is grounded then the balance of electrons occurs. The transfer of the electrons quickly causes the shock.
What is givin off when electrons in an atom fall to a lower orbit?
Energy (in the form of photons) is given off when electrons in an atom fall to a lower energy level.
How were electrons produced from the cathode ray ube?
Filament heats a cathode until it gives off electrons.
How many electron should removed from lead to have gold?
It's not that simple, because Gold has a different proton, neutron and electron number. In fact it is the proton number that determines what element you have, more or less electrons simply makes an ion, more or less neutrons makes an isotope. Take the most abundant isotope of Lead, 208Pb. It has 82 protons, 126 neutrons and 82 electrons. Gold only has one naturally occurring isotope, 197Au, with 79 protons, 118 neutrons, and 79 electrons. So to convert lead into gold, you will need to strip away 3 electrons (easy) and bombard the nucleus with particles to try to knock off 3 protons (prohibitively expensive, even if it was possible). Even if you did so, you might end up with an unstable (radioactive) nucleus, as the highest neutron number observed in synthetic gold is 120.
In the photoelectric effect what happened when light hits the metal?
electrons are knocked off atoms causing electricity to flow
Is energy given or taken off with electrons?
It is given off

Why is silver more conductive than gold?
Conductivity is related to the size of an atom - the bigger the atomic radius, the easier it is to pick electrons off the edge of the atom. Silver has a larger atomic radius (160 pm) than gold (135 pm), despite the fact that gold has more electrons that silver. One caveat though is that in the presence of oxygen silver will corrode and thus become a worse conductor than gold, Gold on the other hand (except under certain extreme conditions) does not corrode, that's why electrical contacts are often gold tipped, to prevent signal degradation do to corrosion.
When did US go off gold standard?
us went off gold standard in 1933
How do you remove freewheel off pocket bike?
you go and lend it to someone who knows how to do it im sorry but there is no other way
What is the difference off HeartGold and gold?
gold is an abbreviated form of Heart Gold
