2 protons and 2 neutrons only
2 electrons, 2 protons and 2 neutrons
2 electrons and 4 protons only
2 protons only

Answer 1

and the decay is written as;

\({}_Z^AX \to {}_{Z - 2}^{A - 4}Y + {}_2^4He\)

Here, A is the atomic mass number, Z is the atomic number and He is the helium nucleus.

EXPLANATION:

A radioactive nucleus emits an alpha particle when two protons and two neutrons from it come out due to quantum tunneling. An alpha particle has a positive charge of two protons.

Hence option 1) is the correct answer.
