Which statement describes a molecule that has a trigonal pyramidal molecular shape? A. The molecule has a trigonal planar electron domain geometry with one lone pair.

B. The molecule has a tetrahedral electron domain geometry with one lone pair

C. The molecule has a trigonal planar electron domain geometry with two lone pairs.

D. The molecule has a tetrahedral electron domain geometry with two lone pairs

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.
