Study Notes

Elements and Molecules

An element is a pure substance consisting of only one type of atom, which cannot be broken down into simpler substances by chemical means.
Elements are organized in the periodic table, categorized by their atomic number, which represents the number of protons in the nucleus of an atom.
A molecule is formed when two or more atoms chemically bond together; it can consist of atoms from the same or different elements.

Subatomic Particles

The neutron is a subatomic particle that has no charge, contributing to the mass of an atom without influencing its electrical properties.
Electrons carry a negative charge, denoted as -1, and are found in the electron cloud surrounding the nucleus of an atom.

Particle Mass Comparison

The electron has the smallest mass among subatomic particles, significantly lighter than protons and neutrons, influencing atomic structure and chemical behavior.
