Calculate the charge on `._(26)F^(56)` nucleus. Given charge on a proton `=1.6xx10^(-19)` C.

Answer

To calculate the charge on the nucleus of the isotope \( _{26}^{56}F \), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Atomic Number and Mass Number**:
The atomic number (Z) of the isotope \( _{26}^{56}F \) is 26. This indicates the number of protons in the nucleus. The mass number (A) is 56, but for this calculation, we only need the atomic number.

2. **Determine the Number of Protons**:
The number of protons in the nucleus is equal to the atomic number. Therefore, the number of protons \( N_p = 26 \).

3. **Charge of a Proton**:
The charge of a single proton is given as \( e = 1.6 \times 10^{-19} \) C.

4. **Calculate the Total Charge of the Nucleus**:
The total charge \( Q \) on the nucleus can be calculated using the formula:
\[ Q = N_p \times e \]
Substituting the values we have:
\[ Q = 26 \times (1.6 \times 10^{-19}) \]

5. **Perform the Multiplication**:
\[ Q = 41.6 \times 10^{-19} \text{ C} \]

6. **Convert to Scientific Notation**:
To express \( 41.6 \times 10^{-19} \) in proper scientific notation, we move the decimal point one place to the left:
\[ Q = 4.16 \times 10^{-18} \text{ C} \]

7. **Final Answer**:
The charge on the nucleus of \( _{26}^{56}F \) is:
\[ Q = 4.16 \times 10^{-18} \text{ C} \]
