Chemistry

Ostrovityanka [42]2 years ago

When   an  atomic  nucleus  emits  an  alpha  particle  it  decay  into  an atom   with atomic  number  2  less   and   mass number  4  less.  Thus  Thorium   230   decay    as  follows.

230 90Th  -------> 226  88Th  +  4 2 He

thorium  is  in  the  atomic  number   90  thus  it  during   alpha decay  it reduces  to  atomic  number  88  while  its  230   mass  number  reduces  to   226

Water is composed of the same elements as hydrogen peroxide why do these substances have different properties
Dmitrij [34]
They have different ratios of elements. Water is H20 and Hydrogen Peroxide is H202. The extra oxygen atom in hydrogen peroxide causes it to be structured and react differently.
