Who explained that electrons move is specific paths around the nucleus?
From Wikipedia: The term "orbital" was coined by Robert Mulliken in 1932.[2] However, the idea that electrons might revolve around a compact nucleus in an orbit-like path was convincingly argued at least 19 years earlier by Niels Bohr,[3] and perhaps the most iconic image of the atom, with electrons orbiting a nucleus along three symmetric directions, was drawn in 1904 by Japanese physicist Hantaro Nagaoka.[4] Explaining the behavior of these electron "orbits" was one of the driving forces behind the development of quantum mechanics.[5] http://en.wikipedia.org/wiki/Atomic_orbital
Is there a positron in the nucleus of an atom?
There are no positrons in the nucleus of any atom. Positrons are anti-electrons; they are antimatter. They could be said to be the antimatter equivalent of the electron, and, as such, they would be present around the nucleus of an antimatter atom as the electrons are present around the nucleus of a "regular" atom. Positrons can be produced in atomic nuclei by some kinds of radioactive decay, and they can be observed to be leaving a nuclear reaction called beta plus decay. But the positron leaves the nucleus of an atom as soon as it is created. It does not (cannot) exist in the nucleus of an atom.
The nucleus or atom left behind when a nucleus disintegrates or splits is?
Sometimes radioactive
What time does the moon take to revolve the sun?
365.24 days, exactly the same length of time as the earth takes. If the moon took more or less time than the earth does to revolve around the sun, even by a very small amount, then over a period of many years, the moon would either pull way ahead of the earth, or else fall far behind. That doesn't happen, because earth and moon revolve around the sun together, in the same time.
How can static build up through contact?
Electrons are constantly revolving around atoms, which in turn make up molecules. These electrons jump from one referential body to another, which is the reason behind static.
How do you describe orbital or shell?
A probabilistic function that describes the possible positions of one of the sets of electrons 'orbiting' the nucleus of an atom. For instance, the oxygen atom has two such shells, one consisting of a 'cloud' of two electrons and the other of six. The shapes of the density functions of individual electrons in these shells vary in shape depending on which shell is involved.
How do the outer electrons in metal atoms differ from the outer electrons in nonmetal atoms?
Those electrons are called the valence electrons. They are the ones that can be transferred and form bonds with other atoms.
What is the physics in electronics?
Firstly electricity is the flow of electrons. An electric current moves in the opposite direction to that of the electrons themselves (unless i think you live in Canada... at any rate one country changed it) and as such is thought of as the 'positive' flow of electrons. So although electrons move from the negative to the positive terminal of a circuit, the current flows from the positive to the negative. basic formula for looking at circuits: V=I*R V= voltage (in volts, the amount of energy that each coulomb has (Joules/coulomb)) I= current (in Amperes, basically speed of electricity(Coulombs/second)) R= resistance (in ohms, the amount of J*s/C^2, or total energy divided by coulombs squared) Electrons are orbiting charge particles around the nucleus and the number differs as shown in the periodic table. However if a potential is applied they leave said orbit and flow to the next nucleus leaving a hole behind. therefore as the electrons flow from positive to a more negative potential these HOLES flow in the opposite direction as a consequence. In the USA it is acceptable as electron flow. But the principle and result is the same if you understand it.
When a Uranium 238 emits an alpha particle the nucleus left behind has how many protons?
90 protons left
What crystals conduct electricity because valence electrons are free to move throughout the crystal lattice?
p type semiconductors. These semiconductors have small concentrations of dopant atoms which have insufficient bonding electrons, so there are "holes" in the bonding arrangements. As electrons jump into these places the holes move in the opposite direction because the jumping electrons leave these spaces behind. So the spaces move around inside this sea of overwhelming bonding electrons. It is called hole conduction, or p-type conductivity. For example silicon doped with gallium.
What idea did Rutherford add to the atomic theory?
the idea behind rutherfords atomic theory is that the atom has a central positive nucleus and negatively charged electrons, which move in orbits, surround it. most of the atom is made up of empty space. he assumed this theory through a gold-foil experiment about which you can find information on the internet.
How do alpha particles beta particles and gamma rays originate in the nucleus of the atom?
A beta particle is created when a neutron inside an unstable nucleus changes into a proton (or vice versa), losing energy and mass in the form of an electron (or positron), which is the beta particle.
