• This module comprises activities that will help deepen your understanding on the properties and characteristics of atoms and how they affect the chemistry present in our daily lives.
• To achieve the objectives cited above, you are to take your time reading the lessons carefully, follow the directions and/or instructions in the activities and exercises diligently, and answer all the given tests and exercises.
• This part contains learning objectives that are set for you to learn as you go along the module.
• This part connects previous lesson with that of the current one.
• At the end of this module, you should be able to use quantum numbers to describe an electron in an atom, determine the magnetic property of the atom based on its electronic configuration, and draw an orbital diagram to represent the electronic configuration of atoms.
• The unwavering pursuit of scientists to come up with different experiments and theories altered our concept of nature forever.
• An introduction of the new lesson through various activities, before it will be presented to you.
• The lessons contained in this module are: Quantum Numbers, Electron configuration and the Magnetic Property of Atoms.
• These are follow-up activities that are intended for you to practice further in order to master the competencies.
• Early efforts by nineteenth-century physicists to comprehend atoms and molecules met with only limited success.

• Understanding the role of quantum numbers in chemistry is important as they provide information about the location of electrons in an orbital and can be used to determine the electron configuration of an atom.
• The electron configuration of an atom should also be represented through orbital diagrams.
• In lesson 1, we learned that electrons have four quantum numbers which describe the location of electrons in an orbital and can be used to determine the electron configuration of an atom.
• The symbol of the element in the first period with 2 valence electrons and used to inflate party balloons is He.
• An electron can be described by the following set of quantum numbers: n=1, ℓ=1, ml=-1, ms=-1/2.
• Quantum numbers provide information about the location of an electron or set of electrons, which can be described in various ways such as GPS coordinates, qualitatively describing surroundings, using a map, etc.
• The symbol of the element in the third period with 5 valence electrons and is used in the manufacture of safety matches is K.
• Being aware of your location and surroundings is important as it helps in understanding your surroundings and avoiding potential hazards.
