1. Kaolinite, a clay mineral with the formula Al Si. O(OH), is used as a filler in slick-paper for magazines and as a raw material for ceramics. Analysis shows that 14.35 g of kaolinite contains
8.009 g of oxygen. Calculate the mass percent of oxygen in kaolinite.
A. 1.792 mass%
B. 24.80 mass%
C. 30.81 mass %
D. 34.12 mass %
E 55.81 mass %

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.
