![]() ![]() ![]() The above differences also help distinguish and identify whether a given unknown compound is ionic or molecular, by conducting appropriate tests in a lab, and finding out the differences in chemical and physical properties of the compound. The methane molecule is this group of 5 atoms connected as such. A covalent bond is a type of bond that occurs between two nonmetals. ![]() Molecular compounds are compounds made up of nonmetals. An Ionic bond is a type of bond that forms between a metal and a non-metal. Ionic compounds have a higher melting and boiling point than molecular compounds. There are four bonds from a central carbon (C) linking or bonding it to four hydrogen atoms (H). Ionic compounds are composed of positive and negative ions held together by ionic bonds.Molecular compounds are softer and more flexible as compared to ionic compounds.Molecular compounds are more flammable than ionic compounds.The enthalpy of fusion (heat energy absorbed when a solid melts) and enthalpy of vaporization (heat energy absorbed when a liquid boils) are higher in ionic compounds.Ionic compounds are more reactive than molecular compounds. Chemical bonds are formed when atoms lose, gain, or share valence electrons to completely fill their outermost electron shell.A molecular compound cannot conduct electricity in any state, whereas an ionic compound, when dissolved in an aqueous solution, can act as a good conductor of electricity. Ion: an electrically charged atom or group of atoms Molecule: a neutral group of atoms joined by covalent bonds Ionic Compounds Ionic bonds (between two.Ionic compounds are charged ions, whereas molecular compounds consist of molecules.In ionic compounds, the ions are held together due to electrical attraction, whereas, in molecular compounds, the atoms are held together by the attraction between the atoms due to shared electrons.Figure 3.5.1: (a) A sodium atom (Na) has equal numbers of protons and. Compounds are classified as ionic or molecular (covalent) on the basis of the bonds present in them. An ionic compound is formed by the reaction of a metal with a non-metal, whereas a molecular compound is usually formed by the reaction of two or more non-metals. Covalent bonds are the attractive forces between the positively charged nuclei of the bonded atoms and one or more pairs of electrons that are located between the atoms. Molecular compounds are pure substances formed when atoms are linked together by the sharing of electrons, while ionic compounds are formed due to the transfer. ![]()
