B. 1 +8 > 2 + 4

Explanation:

Hello!

In this case, since inequalities show how a number is different, greater or less than, to an other, considering the given options, just B. 1 +8 > 2 + 4  is an inequality because if we solve the operation we obtain:

9 > 6

Which means that nine is greater than 6.

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.
