Is sodium a non polar covalent bond?

Answer 1

Sodium(Na) is an element found on group I on the Periodic Table of elements. It is most commonly found present in the compound NaCl, Sodium chloride, better known as salt. Nearly always the metals in group I (including sodium) and group II will form ionic compounds, i.e they don't form covalent bonds at all! Remember a covalent bond is where two atoms share a PAIR of electrons. An ionic bond is where one atom has a negative charge and another atom has a positive charge, the reason they bond is due to their 'wanting' to cancel out their charges. So I presume you meant to ask '' Does sodium form non-polar covalent bonds with other atoms?'', the answer is NO. However on an advanced note, could sodium form POLAR covalent bonds? Maybe, not sure . Remember, a polar covalent bond means where one of the atoms in a covalent bond has a higher tendency to attract the electrons in it, creating a 'polarity' i.e charge difference. The best example of non polar covalent bonds are between carbon atoms. There's many cases where an ionic bond can be somewhat covalent aswell and vice versa (apparently NaCl bond is 29% covalent?!) .There's a thing called the Linus Pauling scale of electronegativity which allows rough prediction of what type of bonds atoms will form with each other. The truth is that bonding theory is actually very complex and is not explained well at all in school, I'm 3/4 through my chemistry degree and I Still only get the jist of it. I know i went on a bit of a rant, but I hope I helped someone out there none the less.
