Calculate the density of the block below, if it has a mass of 27 g using the correct number of significant figures. 5 cm 10 cm 20 cm 02.7 x 104 g/cm3 0 0.027 g/cm² 37.04 g/cm3 O 35 g/cm3

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.
