Physical Science Final Review

A full valence shell is when an atom has the maximum number of electrons in its outermost shell, typically 8 for most elements, which makes it stable and less reactive.

An element is a pure substance made of only one type of atom, while a compound is a substance formed when two or more different types of atoms bond together chemically.

There are 6 atoms of Carbon in the formula $$C_{6}H_{12}O_{6}$$ .

Acceleration (a) is calculated using the formula: $$a = \frac{F}{m}$$ , where F is the net force and m is the mass.

The unit of force in the SI system is the Newton (N).

The proton is the subatomic particle that has a positive charge.

A neutron has no charge; it is neutral.

The atomic number indicates the number of protons in an atom's nucleus and determines the element's identity.

The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction; it can only change forms.

A chemical reaction is a process where reactants are transformed into products through the breaking and forming of chemical bonds.
