What is the element
that has 6 protons 7 neutrons and 7 electrons

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.

the answer should be a
