Ways Atom Combine
Atoms have neutrons, protons and electrons. When atoms come
together they all have outer levels and inner levels. Atoms are made up
of ions. Ions are charged particles because they now have either more or
fewer electrons than protons. Atoms come together in four different
ways, ionic, covalent. single covalent and multiple covalent bonds. An
ionic bond is the force of attraction between the opposite charges of the
ions in an ionic compound. A covalent bond is the attraction that forms
between atoms when they share electrons. A single covalent bond is
made up of two shared electrons. Usually, one of the shared electrons
comes from one atom in the bond and the other comes from the other
atom in the bond. A multiple covalent bond is a bond that contains two
or more shared pairs of electrons.
