Answer:
Carbon atoms
Explanation:
Mass no. of an element= no. of protons + no. of neutrons = 6 + 7 = 13
Atomic no. = no. of protons/electrons = 6
There is an unbalanced situation between the neutron no and proton no. so this has to be an isotope of Carbon-12, and this element is Carbon-13.
I need to be more specific
They did not have the materials
