o
Understand and apply knowledge of the structure of atoms.
o Atomic structure
Matter is made of minute particles called atoms, and atoms are composed of even
smaller components. These components have measurable properties, such as mass and
electrical charge. Each atom has a positively charged nucleus surrounded by
negatively charged electrons. The electric force between the nucleus and electrons
holds the atom together.
o Atomic nucleus (composition and size)
The atom’s nucleus is composed of protons and neutrons, which are much more
massive than electrons. When an element has atoms that differ in the number of
