Pregunta 41

Two atoms have different neutron counts but both have six protons. What must be true?

  1. They are the same element.Respuesta correcta
  2. They must have different element identities.
  3. One must have no electrons.
  4. Changing electron count would necessarily change their element.

Explicación

Both atoms are the same element because element identity is determined by the six protons in each nucleus. A change in neutron count can change the nuclide without creating a new element.
