<span>The atomic number tells you how many _PROTONS_ are in the _NUCLEUS_ of an atom of that element. :)</span>
Most likely the geometric form of the molecule will be linear.
Explanation:
One possibility is the central atom being an atom with two valance electrons. This will create a liner molecule with no lone pairs of electrons
Another possibility is a central atom being an atom with four valance electrons. If the two atoms each require two bonds like oxygen the result will be a linear molecule with no lone pairs of electrons.
