If an element has 6 protons and its mass number is 14, how many neutrons and electrons does it have?

8 neutrons and 6 electrons

Explanation:

Mass number= neutrons + protons

14=x+6

x=14-6

x=8

protons=electrons

6 protons=6 electrons

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
