Everything is made of atoms To comprehend electrical energy, some basic details about atoms is handy. Atoms are the building blocks of deep space. Everything in deep space is made from atomsevery star, every tree, and every animal. The human body is made of atoms. Air and water are made from atoms, too.

Atoms are made from even smaller particles The center of an atom is called the nucleus. The nucleus is comprised of particles called protons and neutrons. Electrons spin around the nucleus in shells. If the nucleus was the size of a tennis ball, the atom would be the size of a sphere about 1,450 feet in size, or about the size of one of the biggest sports arenas on the planet.

If the naked eye might see an atom, it would look a little like a tiny cluster of balls surrounded by giant undetectable bubbles (or shells). The electrons would be on the surface area of the bubbles, constantly spinning and moving to stay as far from each other as possible.


The protons and electrons of an atom are brought in to each other. They both carry an electrical charge.  More Discussion Posted Here  have a favorable charge (+) and electrons have a negative charge (-). The favorable charge of the protons amounts to the unfavorable charge of the electrons. Opposite charges draw in each other.

The neutrons carry no charge and their number can differ. The number of protons in an atom identifies the kind of atom, or component, it is. An aspect is a substance consisting of one kind of atom. The Table Of Elements of Components shows components with their atomic numbersthe number of protons they have.


Electricity is the motion of electrons between atoms Electrons generally remain a consistent range from the atom's nucleus in accurate shells. The shell closest to the nucleus can hold 2 electrons. The next shell can hold up to eight. The outer shells can hold even more. Some atoms with many protons can have as numerous as seven shells with electrons in them.
