What are the definitions of key chemistry concepts such as atom, mass number, isotope, element, compound, mixture, ionic bonding, and covalent bonding?
Understand the Problem
The question consists of definitions and explanations related to fundamental concepts in chemistry, such as atoms, compounds, bonding, and reactions. It aims to provide clarity on basic terminology in the field.
Answer
Definitions include atom, isotope, element, compound, mixture, ionic and covalent bonding.
Here are the definitions of the key chemistry concepts:
- Atom: The smallest unit of an element with all its characteristics.
- Mass Number/Nucleon Number: Sum of protons and neutrons.
- Isotope: Same element, same atomic number, different neutrons.
- Element: One type of atom.
- Compound: Two or more different atoms chemically joined.
- Mixture: Two or more components not chemically bonded.
- Ionic Bonding: Transfer of electrons forming ions.
- Covalent Bonding: Sharing of electron pairs.

More Information
These definitions cover basic chemistry concepts essential for understanding the composition and behavior of matter.
Tips
Students may confuse compounds and mixtures because they both involve multiple substances. Remember, compounds are chemically bonded, mixtures are not.
