Atomic Basics
This particle has a positive charge and is found in the nucleus.
👉 What is a proton?
Opposite charges do this when near each other.
👉 What is attract?
This law describes the force between charged objects.
👉 What is Coulomb’s Law?
This is a region where a charged object experiences a force.
👉 What is an electric field?
Materials that allow electrons to flow easily are called this.
👉 What are conductors?
This particle orbits outside the nucleus and is involved in electricity.
👉 What is an electron?
Like charges do this.
👉 What is repel?
Force decreases with the square of distance. This type of relationship is called this.
👉 What is an inverse square law?
Electric field direction is defined as the direction a ___ charge would move.
👉 What is a positive charge?
Materials that resist electron flow are called this.
👉 What are insulators?
Atoms are mostly made of these three particles.
👉 What are protons, neutrons, and electrons?
Charge cannot be created or destroyed—only transferred. This is called this principle.
👉 What is conservation of charge?
This force always attracts and never repels.
👉 What is gravity?
The equation relating force, charge, and electric field is this.
👉 What is F = qE?
This happens when objects gain or lose electrons through rubbing.
👉 What is static electricity?
The number of these determines what element an atom is.
👉 What are protons?
The unit used to measure electric charge.
👉 What is a coulomb?
The unit used to measure force.
👉 What is a newton?
The electric field of a positive charge points in this direction.
👉 What is away from the charge?
A neutral object can become temporarily charged by this effect.
👉 What is polarization?
These particles have no charge and do not affect electricity.
👉 What are neutrons?
The smallest unit of charge comes from this particle amount.
👉 What is the charge of one electron (or proton)?
Compared to gravity, the electric force is this many times stronger between electrons.
👉 What is extremely stronger (about 10⁴⁰ times stronger)?
The electric field inside a conductor in equilibrium is this value.
👉 What is zero?
This device builds up static charge and can make hair stand up.
👉 What is a Van de Graaff generator?
