Look on the periodic table it should be above atomic symbol
The answer is the half life of phosphorus-32 is of 14 days .
<h3>What is Half Life ?</h3>
The half-life of a radioactive isotope is the amount of time it takes for one-half of the radioactive isotope to decay.
The half-life of a specific radioactive isotope is constant; it is unaffected by conditions and is independent of the initial amount of that isotope.
Mass of atoms initially,
N₀ =2.0 g
Mass after 42 days,
N =0.25 g
mass left undecayed we have,
where n is number of half lives occured (the number of times it disintegrated into half of original)
n= 3
number of half lives occured in 42 days is 3
if half life is
then
3* ( ) = 42
= 14 days
Therfore the half life of phosphorus-32 is of 14 days .

Answer:
Nitrile, amide, carboxylic acid, phenyl (aka. arene)
**There are so many functional groups, so I may list some you don't know. There may also be some that I am not aware of. However, these are all the ones I can see.**
Explanation:
Nitrile: (bottom-left) N triple bonded to C
Amide: (middle) N single bonded to 3 carbons
Carboxylic Acid: (bottom-right) C-CO2H
Phenyl: (top-right) six carbon ring with alternating double bonds
