If i'm missing half of my front tooth, would bonding work to fix this?

Depends on depth: As long as the damage does not extend below the level of the gums and does not extend into the nerve chamber (pulp tissue) of the tooth, a composite bonding is a suitable choice of restorations. Keep in mind, though, that the larger the filling- the less tooth structure you have to support the filling. At a certain point, consider a protective crown to protect your tooth and restore your smile.

Depends: If too much of the tooth is missing then there is no foundation to support a bonded filling reconstruction. In that case, a crown is necessary.

Yes but...: It is not the strongest option. If indeed half the tooth is missing i would recommend more of a crown or partial crown like a veneer. Porcelain bonding is a stronger option for the tooth.
