- An atom is the smallest particle which has the properties of an element.
- Subatomic Particles: Particles that are smaller than an atom usually referring to protons, neutrons and electrons.
- Atomic Number is the number of protons in an atom.
- Nucleus: The tiny, very dense, positively charged region in the center of an atom made up of protons and neutrons.
- The Bohr Model is a model of the atom that contains a positively charged nucleus orbited by negatively charged electrons in specific orbital shells or energy levels.]]> 2021-03-17 02:10:08 UTC https://padlet.com/dwang5463/muoimcs1g5lpwssg/wish/1318636124 dwang5463 https://padlet.com/dwang5463/muoimcs1g5lpwssg/wish/1318658506 Unit 2: Molecular and Ionic Compound Structure and Properties.
- An ionic bond is formed when one or more electrons are transferred from one atom to another.
- A covalent bond is a chemical bond formed when two or atoms share electrons.
