Calculating the Mass of a Lithium Nucleus

To calculate the mass of a lithium nucleus, we can use the atomic mass of lithium and the number of protons and neutrons in its nucleus.

Lithium's Atomic Number and Atomic Mass: Lithium has an atomic number of 3 and an atomic mass of approximately 6.94 atomic mass units (u).

Number of Protons and Neutrons in a Lithium Nucleus: A lithium nucleus contains 3 protons and typically 4 neutrons.

Calculating the Mass of the Lithium Nucleus: To find the mass of the lithium nucleus, we can add the masses of its protons and neutrons.

The mass of a proton is approximately 1.0073 u, and the mass of a neutron is approximately 1.0087 u.

Therefore, the mass of a lithium nucleus can be calculated as: \[ (3 \times 1.0073 \, \text{u}) + (4 \times 1.0087 \, \text{u}) \]

Let's calculate the mass of the lithium nucleus.
