Francis Acosta · Answer 2

a neutron-to-proton ratio of 1:2 in a large nucleus

any isotope of the element uranium, which has atomic number 92

a nucleus that contains 90 protons and 100 neutrons

Explanation:

Basically the the larger a nucleus gets the more unstable it becomes. that's why all elements 87 and above are radioactive
