Ions are formed by electron loss or gain. Ionic compounds consists of a pair of ions.
Ionic compounds are made up of ions. Ionic compounds are formed when metals donate electrons to nonmetals. They have high melting and boiling points and are good electrolytes. However, they do not have low melting points.
Metals are bonded together by a metallic bond. A metallic bond consists of metal cations and a sea of valence electrons. This sea of free valence mobile electrons are the reason why metals are good electrical conductors.
Molecules of a substance in a particular state of matter are held together by intermolecular forces. The strength of different intermolecular forces vary. However, the weakest intermolecular force is van der waals forces.
When atoms of elements loose or gain electrons they form ions. Positive ions are formed by electron loss while negative ions are formed by electron gain. The correct name of the element, the symbol for the ion, and the name of the ion in the list is; copper, Cu+, cuprous ion

Calcium (Ca)(On the periodic table, ionization energy increases as you go up and to the right of the periodic table)
glycoproteins
Explanation:
A positive reaction for Molisch's test is given by almost all carbohydrates (exceptions include tetroses & trioses). It can be noted that even some glycoproteins and nucleic acids give positive results for this test (since they tend to undergo hydrolysis when exposed to strong mineral acids and form monosaccharides).
