Answer :
To determine the correct statement about the chemical behavior of Atom A and Atom B based on their number of electrons, let's analyze them one by one.
### Analysis of Atom A
Given:
- Atom A has 10 electrons.
Step-by-step analysis:
1. Atoms tend to achieve a stable electron configuration, often by attaining a full valence shell.
2. For many elements, a stable configuration corresponds to having 8 electrons in their outermost shell (following the octet rule).
3. However, for atoms with fewer total electrons, configurations can be stable if the shell is completely full.
4. The configuration of Atom A with 10 electrons corresponds to a noble gas configuration (Neon) which is typically very stable.
However, to achieve interaction with other elements, if an atom has a full outer shell but less than the required for more complex interactions, it might prefer to give up electrons to achieve stability in compound formation:
- Thus, Atom A tends to give up electrons to form chemical bonds.
### Analysis of Atom B
Given:
- Atom B has 18 electrons.
Step-by-step analysis:
1. A total of 18 electrons means Atom B likely has a full second shell (8 electrons) and a full third shell (8 electrons considering Argon, a noble gas).
2. With a full valence shell, Atom B is chemically stable and unreactive.
### Conclusion
Based on the analysis:
- Atom A will give up electrons to form bonds because it has a total electron configuration that suggests it can achieve stability through such interactions.
- Atom B, having 18 electrons, has a full outer shell, making it chemically unreactive.
Therefore, the correct statements are:
- "A will give up electrons to form bonds."
- "Both A and B will be chemically unreactive."
As per the provided options, the statements that correctly describe the chemical behavior of Atoms A and B are:
"A will give up electrons to form bonds." (for Atom A)
"Both A and B will be chemically unreactive." (collectively describing Atom B's stability due to its full valence shell)
Thus, the combined correct answer from the given options is:
"Both A and B will be chemically unreactive."
So, the correct statement is:
"Both A and B will be chemically unreactive."
