Which product is formed by beta emission from phosphorus -32? The atomic number of phosphorus is 15.

A)28 Al 13
B)30 Al 13
C)32 S 16
D)32 P 15
E)33 P 15

  • Chemistry -

    Written this way, 15P^32 means 15 atomic number (which is phosphorus) and ^32 means mass number.
    15P^32 ==> -1e^0 + X
    The subscripts must add up on both sides as does the mass number; therefore, X will be 16X^32. What is 16X^32.
