Q. Consider the following statements:
1.A nuclide is a specific type of atom characterized by its number of protons, neutrons, and nuclear energy state.
2.Isotopes are variants of a chemical element that have the same number neutrons but different numbers of protons.
3.In nuclear physics, drip lines refer to the boundaries beyond which nuclei are unstable and will undergo radioactive decay by emitting protons or neutrons.
Which of the statements given above are correct?

[A] 1 and 2 only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: C
Notes:

Explanation –

Statements 1 and 3 are correct. A nuclide is a specific type of atom characterized by its number of protons, neutrons, and nuclear energy state. Nuclides can be stable or unstable. Stable nuclides have a nucleus that is stable and does not undergo radioactive decay. Unstable nuclides have a nucleus that is unstable and will eventually undergo radioactive decay to form a different nuclide.

Nuclides are an important concept in nuclear physics, as they allow scientists to distinguish between different types of atoms with the same atomic number.

In nuclear physics, drip lines refer to the boundaries beyond which nuclei are unstable and will undergo radioactive decay by emitting protons or neutrons. These boundaries are important in understanding the limits of nuclear stability and the nature of nuclear forces.

Statement 2 is incorrect. Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons. Isotopes of an element have the same chemical properties, but they can have different physical properties, such as different masses and half-lives.
