Electricity and Atomic Structure Vocabulary

Vocabulary flashcards covering atomic structure, electricity, utilization of electricity, static electricity, current electricity, and examples from the lecture.

Atom

The basic building block of all matter in the universe, consisting of three tiny types of particles: protons, electrons, and neutrons.

Nucleus

The heavy center of the atom that holds protons (which have a positive charge) and neutrons (which have no charges).

Electron Clouds

A space around the nucleus where tiny, negatively charged electrons move very fast.

Utilization of Electricity

Involves safely and efficiently converting electricity into mechanical power, heat, and light.

Electricity

The flow of tiny, negatively charged particles called electrons from atom to atom, serving as a form of energy that can be harnessed to power devices.

Static Electricity

The build of electric charge on the surface of an object, usually caused by friction (like rubbing two objects together).

Current Electricity

The continuous controlled flow of electrons through a material, typically a wire, which is used to power lights and appliances.

Examples of Static Electricity

Doorknob shock, balloon on hair, dryer cling, combing hair, and taking off a sweater.

Examples of Current Electricity

Lightning, Aurora borealis, bioelectricity, alternating current, and direct current.
