An unstable isotope that naturally decays can emit which of the following? choose all correct responses, there are at least two. {hint: probably are more than two}
question options:
a) alpha particle
b) beta particle
c) radiation
d) positron
e) gamma rays
f) visible light

Isotopes are the species which have same number of protons but differs in the number of neutrons. Or in other words isotopes have same atomic number but different mass number. Isotopes are generally unstable and decays to an stable isotope. When the isotope is unstable it releases energy in the form of radiations. It emits alpha particle, gamma rays, and beta particles.

Therefore, the correct option is (A),(B) and (C)

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.

i think so it’s will be b yes i believe its
