Boron has an atomic number of 5. How many neutrons are found in boron-10 and how many are found in boron-11?

Answer 1

Answer:

10 neutrons in boron-5

11 neutrons in boron - 6

since they are isotopes there atomic weight is given after them which consists of protons plus neutrons hence subtract 5 from each to get and as 5 and 6

Answer 2

Answer:

neutrons=atomic mass-atomic number

for boron 10 atomic mass=10

while boron has atomic number 5 irrespective of atomic mass.

hence neutrons in boron 10 are 10-5=5

and neutrons in boron 11 are 11-5=6
