Electricity. Flashcards
What is an atom?
The smallest type of matter is constructed of a nucleus (Proton and Electron) and electrons.
Extra:
In the center the nucleus contains subatomic particles that present positive and neutral charges, and while the electrons reside in orbitals around the nucleus. The nucleus contains most of the mass of the atom and is extremely dense; so dense in fact that it is compared to a 1 by 1 by a 1-foot box that contains 6.2 billion cars inside of it. Between the nucleus and the electrons in space. SOOOO small in fact, that if the atom was the size of a football stadium, the nucleus would be a marble! If all the space in the atom was taken away from all the atoms, the entire human population could fit in a sugar cube.
What are Electrons, Protons, and Neutrons?
They are subatomic particles that make up an atom.
What possible charges can an atom have?
Negative, positive, neutral.
Negative: Has more electrons
Positive: Has less electrons
Neutral: Has an equal amount of electrons and protons.
Electric charge is a property of matter.
Which subatomic particles move to create electricity and why?
Electrons move and create electricity because they can be attracted to other atoms.
What are conductors?
Conductors are materials, which can move electrons easily. Materials include metal and copper. Conductors are basically atoms with valence electrons, electrons that are the only ones in their shells.
Ex: Copper, with 1 electron that is very weak, in the fourth shell.
What are insulators?
Insulators are materials, which cannot move electrons easily (though it still could). It can be used to contain electricity in a wire. Materials include rubber.
What attracts and what repels?
Like, repel and unlike attract. This affects electricity because the negative terminal of a battery would push the electrons through the circuit.
What is an electric field?
An electric field is an area which electricity exerts a force.
What is current electricity?
Current electricity is a controlled form of electricity. This can be controlled in the form of hydroelectric dams, nuclear energy, tidal power and such.
