Atoms are made of a positive nucleus surrounded by negative electrons.
An atom's electron configuration, particularly the outermost electrons,
determines how the atom can interact with other atoms. Atoms form bonds
to other atoms by transferring or sharing electrons.

Physical Science: Structure of atoms Grades 9-12, page 178 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. NSES Content Standard B
