help with covalent bonds

Question

if it takes one or more covalent bond for any atom to form, then I am confused with these answers.

 

a. one

b. two

c.  as many as it needs to fill its valance shell

d.  there is no limit to the number of convalent bonds which any atom can form.

 

I would think there would have to be a limit, otherwise the shells would be maxed out.

 

thanks

Answer 1

What is the actual question? Atoms don't need covalent bonds at all; from a chemistry point of view, atoms just exist and are not formed. Is the question the maximum number of bonds an atom can have?
