D:
Correct Answer
B
Explanation
To determine the nature of the particle based on its composition of protons, neutrons, and electrons, we can look at the number of protons and electrons.
The number of protons determines the element, and in this case, there are 11 protons. This corresponds to the element sodium (Na), as each element is defined by its unique number of protons.
The number of electrons is 10, which means there is one more electron than the number of protons. This suggests that the particle has a charge of -1, making it an ion. Since it has more electrons than protons, it is a negatively charged ion.
So, the particle with 11 protons, 12 neutrons, and 10 electrons is a non-metallic ion, specifically a non-metallic ion of sodium (Na^−).
