Calculate mass defect and binding energy per nucleon of `""_(10)^(20)Ne` , given
Mass of `""_(10)^(20)Ne = 19.992397 u`
Mass of `""_1^(1)H = 1.007825 u`
Mass of on = `""_(0)^(1)1.008665 u`

Explanation

To calculate the mass defect and binding energy per nucleon of \( _{10}^{20}\text{Ne} \), we will follow these steps:

### Step 1: Determine the number of protons and neutrons in \( _{10}^{20}\text{Ne} \)
The atomic number (10) indicates that there are 10 protons. The mass number (20) indicates that the total number of nucleons (protons + neutrons) is 20. Therefore, the number of neutrons can be calculated as follows:

\[ \text{Number of neutrons} = \text{Mass number} - \text{Number of protons} = 20 - 10 = 10 \]
