Match the following ( array |c|l|c|l| & List-I & & List-II (a) & n ; ; p + & (p) & -decay (b) & p ; ; n + & (q) & Positron emission (c) & x-ray emission & (r) & ⁻ emission (d) & ²²⁶₈₈ Ra ; ; ²²²₈₆ Rn + & (s) & K electron capture array )
Options
- A( a r , b q , c q , d s )
- Ba ( q , b r , c s , d p )
- C( a r , b q , c s , d p )
- Da ( ) q, b ( ) s, c ( ) r, d ( ) p
Correct answer
C. ( a r , b q , c s , d p )
Step-by-step solution
a: ( n p + ) This represents the decay of a neutron into a proton, which is ( )-emission ( ( r )). - b: p ( n + )... This represents the decay of a proton into a neutron, which can be Positron emission (q). - c: x-ray emission X-ray emission is often associated with K electron capture (s), where an inner electron is captured by the nucleus, leading to characteristic X-rays. - d: This is an example of a-decay (p), as the atomic number decreases by 2 and the mass number by 4. Matching these gives: (a r, b q, c s, d p
