Ca is the only element perhaps B
Answer:
c) non polar Covalent
Explanation:
this is a molecule formed by atoms of the same element . they both have similar electronegativities and thus cancel out . This makes it a perfect Covalent molecule . The fact that it's a symmetrical molecule makes it non polar. a symmetrical molecule is a molecule formed by the overlap of orbitals of two atoms of the same element ( that is to say , there's no dipole )
