Question

the diagram illustrates radioactive decay. which statement correctly identifies structures 1 and 2 in the diagram? structure 1 is an unstable atom that turns into structure 2, a new atom. structure 1 is a stable element that breaks down into structure 2, an unstable element. structure 1 is a radioactive element that loses particles to create structure 2, released energy. structure 1 is a radioactive atom that decays into structure 2, half of the original unstable element.

Explanation:

Radioactive decay is the process by which an unstable radioactive atom loses particles and energy to form a new atom. Structure 1 is the initial radioactive atom and structure 2 is the new atom formed after decay.

Answer:

Structure 1 is an unstable atom that turns into structure 2, a new atom.
