A titanium bicycle frame contains the same amount of tita- nium as a titanium cube measuring 6.8 cm on a side. Use
the density of titanium to calculate the mass in kilograms
of titanium in the frame. What would be the mass of a
similar frame composed of iron?

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.
