Test Nov 20 Flashcards
Where are protons electrons and neutrons found in an atom?
The protons and neutrons are found in the nucleus of an atom, and the electrons are found outside the nucleus
When considering electrons which of the above subatomic particle’s are considered to be fixed? Which ones are able to move?
Protons and neutrons are fixed electrons are movers! They move.
What is electricity
Electricity is the movement of electrons moving from one object to another in particular paths.
What is electrostatics?
The study of stationary electric charges or fields as opposed to electric currents
What are the one fluid into food? Explain each model as well as how they are different from one another
The one fluid model is when there is one fluid in every object and a positive object has more of that fluid (negative object has less) to food model is when there are two fluids one that’s positive and one that’s negative when there is more positive fluid in an object then it is positive if there is more negative fluid in an object then it becomes negative science
Explain the 7 points of the particle model of electricity in your own words
1.) all matter is made up of atoms 2.) the cener of the atom is a nucleas made up of protons and neutrons 3.) electrons surround the nucleus 4.) like charges repel, unlike charges attract 5.) some elements the nucleas has a weaker attraction for electrons others are stronger 6.) the number of electrons equal the number protons 7.) an atom that gains an electron is a negative ion, and anything that loses an electron is a positive ion
What does it mean that charge is conserved in the particle model of electricity
It means you cannot create or destroy protons and electrons. You can only move them
Explain what a conductor and insulator is. Give examples of each and explain your examples
Conductors are materials that permit electrons to flow freely from particle to particles. Insulators stop the freedom INSULATORS ARE BAD!!!! THEY ARE AGAINST FREEDOM ex.) copper ex.) plastic
What are the three ways an object may be charged?
Explain this in your own words
Give examples to help you
- ) friction-when two objects rub together electrons can go from one object to another
- ) contact-when a charged pbject touches a neutral
- ) induction-when for example, lightning! The electrons move extremely quickly to a neutral object, even though they’re not touching
What does the term grounding mean? Why is it important for the study of electricity
Grounding means that when you put electricity into the ground, it virtually removes it’s charge, because soil is such a good insulator and soforth. Without grounding I am sure we would be nowhere in life
Grounding means removing it’s UNBALANCED charge
It’s important my the study of electricity because without grounding you wouldn’t be able to make lightbulbs light up! 😭😭😢😢😭😭
Explain how lightning occurs
Lightning occurs when all the electrons want to get to the ground. The negativity wants to become neutral. ZAP
Explain two of the electrostatic phenomena we studied. Why did the movement occur the way it did?
Answer will vary
What is the law of charges?
The law of charges explains that all magnetic objects have the tendency to repel or attract to one another. Opposites attract and similar’s repel
