Physical Science


Physical Science is the study of matter and energy.

Everything in the universe is either matter or energy.

Plants, rocks, clouds, and elephants are all examples of matter.

Lightning, thunder, heat, and sunlight are all examples of energy.

Neon glows in a distinctive color when used inside gas-discharge lamps, such as "neon lights". These lights are called after neon but often contain other gases.
List other gases that are used in "neon lights".

What do their electron configurations have in common?

What are the colors that the different gases glow in?
How are all the different colors found in "neon lights" obtained?


In the early 1800's, an English chemist named John Dalton stated that all matter is composed of atoms and that these atoms cannot be divided or destroyed. His ideas were the beginning of the modern theory of atoms. However, scientists no longer agree with some of them.
Who was the first scientist to suggest that atoms contain smaller particles inside of them?
What did Rutherford discover about the atom?
Who discovered the electron?
Who discovered the proton?
Who discovered the neutron?

Electrons in the outermost energy level (OEL) of an atom are called valence electrons. Except for the elements hydrogen and helium, the OEL of an atom can hold a maximum of eight electrons. An atom with eight electrons in its OEL is very stable.
For the elements Beryllium, Phosphorus, Argon, Iron, Chlorine, Sodium, Xenon, and Silver; how many electrons do their outermost energy levels hold?
Which of them are stable?
Are you able to write their electron configurations?
H atom orbitals
