Question

Element A has 15 protons. Determine the number of neutrons in its isotope with mass number 33.

Answer 1

number of protons=15

mass number=33

number of neutrons=mass number- number of protons
=33-15
=18

there will 18 neutrons in its isotope

hope it helps you

Answer 2

Hey buddy!!☺️☺️
Here's the answer to ur question------>>>>

No. of protons = 15
Mass no. = 33
No. of neutrons = Mass no. - no.of protons
No. of neutrons= 33 -15 = 18.
So, the total no. of neutrons is 18.

Hope it helps❤️❤️❤️
