Lewis structure for Si2H2

See Attached

Explanation:

From the neutral molecule formulae, there are two Silicon atoms and two hydrogen atoms;

Silicon has four (4) valence electrons while Hydrogen has  (1) one. To achieve stable electron configuration. Silicon needs its unfilled orbital to have 8 electrons while Hydrogen needs its only orbital to have 2 electrons. The involved atoms will share electrons to form covalent bonds as shown in the Lewis dot illustration (attached). Notice the double bond between the two Silicon

it's filtration, but this is an assumption so my apologies if i got this
