Atoms will combine with each in order to become more chemically stable. Compounds are formed between two atoms that have
drag and drop answer here outer energy levels. The two types of compounds that can be formed between atoms are ionic and covalent.
Ionic compounds are formed between two drag and drop answer here charged atoms. Ionic compounds contain a drag and drop answer here ion and a
drag and drop answer here ion. Metals will lose electrons to form positive ions and nonmetals will gain electrons to form negative ions. These
oppositely charge ions are very attracted to each other and form very strong bonds as a result. Ionic compounds are characterized by crystalline
structure, drag and drop answer here melting and boiling points, and are drag and drop answer here at room temperature.
Two drag and drop answer here will combine to form covalent compounds. Covalent compounds are formed when two atoms drag and drop answer here
one or more pairs of electrons. The force of attraction between the nonmetals is relatively weak. Covalent compounds are characterized by
drag and drop answer here melting and boiling points and can be gases, liquids, or soft solids at room temperature.
