Study Notes

Atomic Structure

Atoms are the smallest building blocks of all elements.
They are composed of three main particles: electrons, protons, and neutrons.

Electrons, Protons, and Neutrons

There are 98 different elements, each made up of atoms.
Atoms consist of electrons, protons, and neutrons.

Formation of Atoms

An atom is the smallest unit of an element.
Atoms are comprised of protons and neutrons in the nucleus, with electrons orbiting around it.
The nucleus has a positive charge due to protons, while electrons have a negative charge.

Why the Nucleus Pulls Electrons

The attraction between the positively charged nucleus and the negatively charged electrons creates the planetary model of the atom.
This attraction is similar to the Earth pulling on the Moon.
