Write nuclear reaction equations for :
(i) `alpha`-decay of `" "_(88)^(226)Ra` (ii) `alpha`-decay of `" "_(94)^(242)Pu` (iii) `beta^(-)`-decay of `" "_(15)^(32)P`
(iv) `beta^(-)`-decay of `" "_(83)^(210)Bi` (v) `beta^(+)`-decay of `" "_(6)^(11)C` (vi) `beta^(+)`-decay of `" "_(43)^(97)Tc`
(vii) Electron capture of `" "_(83)^(210)Xe`

Explanation

Applying conservation law of mass number and atomic number, the nuclear equations may be written as :
(i)`" "_(88)^(226)Ra overset(alpha-decay)(to)" "_(86)^(222)Rn+" "_(2)^(4)He`
(ii) `" "_(94)^(242)Pu overset(alpha-decay)(to)" "_(92)^(238)U+" "_(2)^(4)He`
(iii) `" "_(15)^(32)P overset(beta^(-)-decay)(to)" "_(16)^(32)S+" "_(-1)^(0)e+ bar nu`
(iv) `" "_(83)^(210)Bi overset(beta^(-)-decay)(to)" "_(84)^(210)Po+" "_(-1)^(0)e+ bar nu`
(v) `" "_(6)^(11)C overset(beta^(+)-decay)(to)" "_(5)^(11)B+" "_(+1)^(0)e+ nu`
(vi) `" "_(43)^(97)Tc overset(beta^(+)-decay)(to)" "_(42)^(97)Mo+" "_(+1)^(0)e+ nu`
(vii)`" "_(54)^(120)Xe + " "_(-1)^(0)e overset("electron capture")(to)" "_(53)^(120)I+ nu`.
