if it occurs between non metal atoms. Covalent bonds can only occur between non metal atoms but Ionic bonds occur between metal and non metal atoms.
No, but it's not a metal, either. A "non-metal" is an element, and "wood" is not a chemical element. So, wood is not a non-metal, and it's not a metal, either. Wood is a very complex substance made of many different molecules, which are made of many different atoms.
metal and non metal
Just one in every molecule, oxygen
Atoms do not have covalent bonds, they form them. A covalent bond is typically non-metal to non-metal, and hydrogen is considered a non meteal
if it occurs between non metal atoms. Covalent bonds can only occur between non metal atoms but Ionic bonds occur between metal and non metal atoms.
the difference of electronegativities of sodium and fluorine is 3.1 so they form ionic bonds . the metals and non metals usually have this difference higher than 1.7 and this and higher difference is always form an ionic bond between atoms
metal
Covalent bonds may contain two non metal atoms. Example is CH4.
it depends on the valency of the atoms

Description belongs to the class of inorganic compounds known as alkali metal fluorides. These are inorganic compounds in which the largest halogen atom is fluorine, and the heaviest metal atom is an alkali metal. Kingdom Inorganic compounds
No "NaF" is Nonpolar covalent because 4.0 - 0.9 is in the Nonpolar covalent range.
yes both the carbon and oxygen are non metal atoms but beside this carbodioxide is lethal
