Helium decays by beta emission, in beta emission, the mass number of the parent and daughter nuclei are the same but the atomic number of the daughter nucleus increases by one hence it is found one place to the right of its parent in the periodic table.
Having said this, the decay of Helium to lithium may be written as follows;
6/2He -> 6/3Li + 0/-1e
