What else can I help you with?
What atomic particle that has a positive and negative changes?
maybe a neutron when Millikan messed with oil drops he kinda thought the steps he saw were unit charges.. now we are getting strange and quarkey and consider an electron to be 2/3 of a unit charge made up of smaller units witch are real unit charges but with the infinite knowledge of the senate and congress the super collider was killed so we may never know.
A magnet produces a magnetic field that points north In what direction does the force on a proton act if it enters this region with a horizontal velocity toward the east?
The proton will circulate clockwise in a plane perpendicular to the the north direction.The proton will move from the east to the west clockwise.
Do holes in semiconductor have mass?
no!!!!! holes in semiconductor have no mass! the conventional way to represent holes as positively charged so there should be a question in our mind that they should have some mass,as proton, the only positively charged particle have mass,but it hasn't.actually the electrons are carrying charge in everywhere,the opposite direction of flow of current considered as the direction of conventional current, In the semiconductor also only electron carry charges,so the excessiveness of electron defined a semiconductor as n-type,or donor type(due to doping,i.e.,mixing some impurities with the semiconductor and make the semiconductor to make covalent bond with that element).and where the semiconductor is doped with some element of having only three electrons at the valence cell,the covalent bond have a shortage of electrons to complete the total covalent bond,so the semiconductor become available to add another electron to compete the covalent bond.and hence they are called p-type or acceptor type.so hole is nothing but a convention to denote this lack of electron,i.e.,lack of negative charge and it seems like the semiconductor have a positive charge that balance the electron.so the hole must not have any mass. electron have a mass-1.6*10^-19 kg
What type of imaging method is SPECT?
Single proton (or photon) emission computed tomography (SPECT) produces three-dimensional images of an organ or body system.
What did the cathode ray tube tell us about atomic structure?
because Thomson saw the ray move from the cathode to the anode so the particles have negatively charge
What is in electricity?
There is a current that has proton, neotron, and electron atoms.
How many sources of electricity are there?
One. The electromagnetic force, represented by the charge on the electron and the proton.
Which part of the atomis responsible for creating electricity?
The electron is the part of the atom that accounts for electricity.
What releases a fast moving electron from a neutron in the nucleus?
Beta decay releases a fast-moving electron (beta particle) from a neutron in the nucleus. During beta decay, a neutron is converted into a proton, and the electron and an antineutrino are emitted to conserve charge and energy.
What are three subatomic paarticles in an atom?
Neutron, proton, electron.Neutron, proton, electron.Neutron, proton, electron.Neutron, proton, electron.
How big is a electron compared to a proton?
A proton is bigger than electron
How big is a proton compared to a electron?
A proton is bigger than electron
How electron is converted into proton?
An electron will not decay into a proton by any means.
Does an electron or proton have a larger charge?
No. The electron and proton have the same amount of charge. Its just that the electron's charge is negative and the proton's charge is positive.
Electron transfer systems concentrate energy that is then used to generate ATP in?
Electron transfer systems, such as the electron transport chain in mitochondria, generate a proton gradient across a membrane. This proton gradient stores energy that is then used by ATP synthase to produce ATP through oxidative phosphorylation. This process is essential for cellular respiration and energy production in most organisms.
How do you charge an atom?
remove either a proton or electron OR add a proton or electron...
Is a proton larger or smaller than electron?
An electron is 1/1,836 of a proton.
