Question

Carbon-14 has 6 protons and 8 neutrons; which element has 6 protons and 7 neutrons?

C-13

Si-14

C-6

Answer 1

proton number shows which element it is
C-14 has 6 protons
and the element they are asking for also has 6 protons
which means they both are C atoms BUT are ISOTOPES
neutron+proton= mass
8+6= 14 is mass for the first C
now they are saying its 6 protons and 7 neutrons
so add them up and get a mass for the isotope of C

Answer 2

is it clear?

Answer 3

it's Si-14

Answer 4

it has 2 be

Answer 5

silcon has 14

Answer 6

nvm ur right

Answer 7

so its C-13

Answer 8

oh okay

Answer 9
