which atom has the greatest number of nuetrons?
S-34 or P-34?

S-34 and P-34 indicate atomic masses of the particular elements. The atomic mass is the number of neutrons plus the number of protons. The number of protons in an atom is its atomic number.
The atomic number for P is 15. The atomic number for S is 16. The number of neutrons in an atom is the atomic mass minus the atomic number.
In this instance, P-34 has more neutrons. (34-15=19) S-34 has one less neutron (34-16=18) because its atomic number is one higher than P, meaning it has one more proton.

Sulphur has an istope S 34, having 18 neutrons
I dont thin there is any isotope of phosphorous as P 34. The only isotope of phosphorous is P 31 which has 16 neutrons. The common forphorous has 15.

i assume its silicon and phosphorous..
mass no of silicon given was 34.
Atomic no.=14
so no of neutrons=mass no.-atomic no.
=34-14=20
mass no of phosphorous given was 34.
At. no=15.
no of neutrons=34-15=19..
hope u r satisfied..
