Answer 1

@Awolflover1 @RhondaSommer @just_one_last_goodbye any of you know?

Answer 2

sorry hun; ive got no clue

Answer 3

alright, thanks anyways

Answer 4

@mayankdevnani do you happen to know?

Answer 5

Any Random Guess?

Answer 6

what is isotope?

Answer 7

i dont kno mayan and awolf, idk A maybe

Answer 8

isotope=same atomic number but different mass number

Answer 9

ok

Answer 10

so find mass number !
mass number=no.of nucleons=no of protons+no of neutrons

Answer 11

A is 6 B is 7 C is 7 and D is 8

Answer 12

or find atomic number=no of protons

Answer 13

if same atomic number,then those are isotopes

Answer 14

A an b are isotopes and C and D are

Answer 15

so it is A?

Answer 16

@mayankdevani is it A

Answer 17

what the heck did he block me

Answer 18

@Ella4184 help

Answer 19

I would have to say C

Answer 20

The number of protons is what determines the element.

If two atoms have the same number of protons but different number of neutrons, they are isotopes

Answer 21

THANK YOU

Answer 22

Anytime:)
