why does co2 have a low boiling point

covalent bond A covalent bond between atoms forms when atoms share electrons to achieve a full outer shell of electrons. form between non-metal atoms. Each bond consists of a shared pair of
electron An electron is a very small negatively-charged particle found in an atom in the space surrounding the nucleus. , and is very strong. Covalently bonded substances fall into two main types: molecule A molecule is a collection of two or more atoms held together by chemical bonds. It is the smallest part of a substance that displays the properties of the substance.


These contain only a few atoms held together by strong covalent bonds. An example is carbon dioxide (CO ), the molecules of which contain one atom All elements are made of atoms. An atom consists of a nucleus containing protons and neutrons, surrounded by electrons. of carbon bonded with two atoms of oxygen. Low melting and boiling points - This is because the weak intermolecular forces break down easily. Non-conductive conduct To allow electricity, heat or other energy forms to pass through. electricity.


This is because they do not have any free electrons or an overall electric charge. Hydrogen, ammonia, methane and water are also simple molecules with covalent bonds. All have very strong bonds between the atoms, but much weaker forces holding the molecules together. When one of these substances melts or boils, it is these weak 'intermolecular forces' that break, not the strong covalent bonds. Simple molecular substances are gases, liquids or solids with low melting and boiling points. Media upload failed.
