Covalent network solids typically have highlow melting points and highlow boiling points. The chemical formula of a network solid indicates only the types of atomsthe actual number of atomsthe ratio of the types of atoms in the molecule.

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
