Using a fragmentation scheme, efficient algorithms can be proposed to address problems in the description of chemical bond formation and breaking. We present a formally exact time-dependent density-functional theory for the electronic dynamics of molecular fragments with variable number of electrons. This new formalism is an extension of previous work [Phys. Rev. Lett. {\\bf 111}, 023001 (2013)].
