What produces heat during shielded metal arc welding?
Electrons flowing across an air gap produce an arc. The resistance built up that is needed to push these electrons across the gap produces the heat. This same resistance causes the electrodes to get hot.
A high powered microscope that produces an image from scattered secondary electrons is the?
Scanning electron microscope (SEM)
What causes the emission of radiant energy that produces characteristics spectral lines?
When the electrons absorb energy from a source, such as heat, they move to an excited state (farther from the atoms nucleus). They then release the energy in the form of light which produces the observed spectral lines of color. Once the energy is released, the electrons move back to a lower energy level (ground state).
Why do electrons behave like tiny magnets?
a spinning electron produces a magnetic field that makes the electron behave like a tiny magnet
Is phosphours magnatic?
Any atom with unpaired electrons in it's orbital exhibits paramagnetism, that is that it will be attracted into an inducing magnetic field. Phosphorous has 15 electrons: 1s>2e-(all paired) 2s>2e- 2p>6e-(all paired) 3s>2e-(these two are paired) 3p>3e-(note that these are the unpaired electrons that cause it to be paramagnetic) All this is because a moving negative charge produces a magnetic field if there are two electrons in the same orbital they always spin in opposite directions cancelling each other out. When there are unpaired electrons that creates the magnetic field.
Electricity produces work when the electrons in a conductor?
Electricity produces work when the electrons in a conductor
What kind of particle that produces electricity?
Electrons produce electricity. Flow of electrons comprises of current.
What produces the flow of electrons with a static electric charge?
Anode
What produces an image with the electron microscope?
A magnetic field focuses he electrons
Electron sharing produces what?
It produces new chemicals. The ions will come together to share the electrons and then a new chemical reaction will occur.
Which part of a cell is the site for a reaction that produces electrons and positive ions?
Anode
What produces the atomic fingerprint of an element?
electrons jumping to a lower energy level.
What is the source of the energy that produces the chemiosmotic gradient in mitochondria?
Main fuel is glucose. It is oxidized using oxygen
What high-powered microscope produces an image from scattered secondary electrons?
electron microscope
What event produces a covalent bond?
Sharing a pair of electrons results in a covalent bond.
What charged particle produces the flow of electricity?
Anything that carries and/or can transport charge.
When electrons of an excited atom falls back to lower levels there is an emission of energy that produces what?
The electrons emit photons of light equal in energy to the energy that was absorbed.
