Topic 1 Flashcards
All matter is made of ______ that are combined together into molecules.
Ex: Water molecule
Atoms
An atom is _______ when it has the same number of protons and electrons.
Neutral
Atoms are _________ charged when there are more protons than electrons.
Positively (more protons+ than electrons-)
Atoms are _________ charged when there are more electrons than protons.
Negatively (More electrons- than protons+)
What are the 3 rules in the Law of Charges?
- Unlike charges attract
- Like charges repel.
- Charged objects attract uncharged (neutral) objects.
What is Static electricity?
It is when a charge is produced by rubbing or touching objects together.
When is static electricity created?
Static electricity is created when no current can flow and there is a buildup of electrons.
The movement of electrons along a wire is known as _______ electricity.
Current
___________: Allow charges to move freely through the substance.
Conductors
______________: objects that can transfer an electrical charge with little to no resistance.
Superconductor
_________: are materials that do not allow charges to move freely on or through them (they do not conduct charges well).
Insulators
_______ _________: allows for unbalanced charges to rebalance by transferring a large number of electrons from one place to another.
Static Discharge
_________ an object to the earth is an effective way of preventing static discharge as the earth is very large and can supply opposite charges easily.
Grounding
What 2 methods do you use to reduce charges?
Grounding and Ionization
