\end{tabular}

A positively charged substance is brought near the ion. What will most likely happen?

A. The negatively charged ion will repel the substance.
B. The negatively charged ion will attract the substance.
C. The positively charged ion will repel the substance.
D. The positively charged ion will attract the substance.

Sure, let's analyze the situation step-by-step:

1. Understanding Ion Charge:
- The ion has 12 positively charged particles and 10 negatively charged particles.
- To determine the overall charge of the ion, we subtract the number of negatively charged particles from the number of positively charged particles:
[tex]\[ 12 - 10 = 2 \][/tex]
- Since the result is positive, the overall charge of the ion is positive. Thus, we have a positively charged ion.

2. Interaction with a Positively Charged Substance:
- It is known from basic electrostatic principles that like charges repel each other while opposite charges attract each other.
- Since the ion is positively charged and the substance brought near it is also positively charged, we need to determine what happens between like charges.

3. Conclusion Based on Electrostatic Principles:
- Like charges repel each other.
- Therefore, when a positively charged substance is brought near the positively charged ion, they will repel each other.

Thus, the correct outcome is:
- The positively charged ion will repel the substance.

So, the correct statement is:
The positively charged ion will repel the substance.
