Question

If the atomic mass of Sodium-18 is 18.02597 u, what is the binding energy?

Answer 1

Answer:

The binding energy of sodium Na=5.407791×10⁹J

Explanation:

Greetings !

Binding energy, amount of energy required to separate a particle from a system of particles or to disperse all the particles of the system. Binding energy is especially applicable to subatomic particles in atomic nuclei, to electrons bound to nuclei in atoms, and to atoms and ions bound together in crystals.

Formula : Eb=(Δm)c²

where:Eb= binding energy

.Δm= mass defect(kg)

c= speed of light 3.00×10⁸ms¯¹

Given values

• m= 18.02597
• c=3.00×10⁸ms¯¹

required value

• Eb=?

Solution:

• Eb=(Δm)c²
• Eb=(18.02597)*(3.00*10⁸ms¯¹
• Eb=5.407791*10⁹J
