Atom Structure and Properties

Removing air from a jar causes marshmallows to expand due to Boyle's Law, which states that pressure and volume are inversely proportional at constant temperature.
Heating a marshmallow causes expansion due to Charles' Law, which states that volume and temperature are directly proportional at constant pressure.
Atoms are the smallest units of matter, composed of subatomic particles, and elements consist of only one type of atom.
There are 118 natural and synthetic elements, with atoms measuring about 10-10 meters.
Atoms have an internal structure and are made of subatomic particles: protons, electrons, and neutrons.
Protons are positively charged, have a mass of about one atomic mass unit (amu), and define an atom's atomic number.
Electrons have a negative charge and participate in chemical reactions, forming ionic or covalent bonds.
Neutrons are located in the nucleus with protons, have no charge, and contribute to the atomic mass.
Isotopes are atoms with a different number of neutrons, some of which are stable, while others undergo radioactive decay.
The periodic table organizes elements by their physical and chemical properties, based on their atomic number and atomic mass.
The atomic number, element abbreviation, and atomic mass in amu are shown for each element in the periodic table.
Understanding the behavior of atoms and their subatomic particles is crucial for comprehending their properties and interactions in chemical reactions.
