Write nuclear reaction equation for
(i) `alpha` decay of `._88Ra^(226)` (ii) `alpha` decay of `._94Pu^(242)` (iii) `beta^(-)` decay of `._15P^(32)`
(iv) `beta^(-)` decay of `._83Bi^(210)` (v) `beta^(+)` decay of `._6C^(11)` (vi) `beta^(+)` decay of `._43Tc^(97)`
(vii) Electron capture of `._54Xe^(120)`.

Explanation

To write the nuclear reaction equations for the specified decays, we will follow the conventions for alpha decay, beta decay (both negative and positive), and electron capture.

### Solution:

**(i) Alpha decay of Radium-226 (Ra-226):**
- An alpha particle (which is \( ^4_2He \)) is emitted from Radium-226.
- The equation for this decay is:
\[
