t Answer Well firstly, ionic compounds form from metals bonding with non metals. Molecular/covalent form from non metals bonding with non metals. A strong electrostatic force between ionic compounds results in them having high melting points. A weaker electrostatic force between molecular compounds results in them having lower melting points and thus weaker bonds. Ionic compounds are made up of ions, so will conduct electricity. Covalent compounds only share electrons and so are not ions, and will not conduct electricity.
Metals share properties such as: malleability, conductivity, strength and hardness. The reason properties of metals are different is because of metallic bonding. metals are made up of positively charged metal ions in a sea of delocalised electrons. This gives them the properties listed above. Ionic and molecular compounds are bonded in different ways. e.d ionic compounds are bonded in a rigid structure so it is brittle and non conductive
The average speed of the random molecular motion increases. The corresponding increase in molecular kinetic energy accounts for what happened to all of that heat energy.
hydrogen bonding
the number of electrons in the outer shell of each atomic particle.
Metallic: melting point @ 63, boiling point @ 760, properties: soft, silvery, solid, and conductor as a solid. Covalent: melting point @ -101, boiling point @ -34.6, properties: greenish yellow gas and not a good conductor.
The elements in a group, also called a family, have similar properties, one of which is the same number of valence electrons. This accounts for why the elements in a group have similar properties.
