Understanding the Stability of Atoms

Atoms with filled outer electron shells are particularly stable and non-reactive. This is because the outermost energy level, also known as the valence shell, is completely filled with electrons. As a result, these atoms do not have a strong tendency to gain or lose electrons, which makes them less reactive.

The Octet Rule

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer energy level, which typically consists of eight electrons. Atoms with filled outer electron shells have already achieved this stable configuration, making them less likely to participate in chemical reactions.

Covalent Bonds in Aqueous Solutions

Option b) states that atoms with filled outer electron shells form covalent bonds in aqueous solutions. However, this is not entirely accurate. Covalent bonds are typically formed between atoms that share one or more pairs of electrons to achieve a stable configuration. Atoms with filled outer electron shells are not likely to form covalent bonds, as they do not have a strong tendency to share electrons.

Ionic Bonds in Aqueous Solutions

Option c) suggests that atoms with filled outer electron shells form ionic bonds in aqueous solutions. This is also incorrect. Ionic bonds are formed between atoms that have a strong tendency to gain or lose electrons, resulting in the formation of ions with opposite charges. Atoms with filled outer electron shells do not have a strong tendency to gain or lose electrons, making them less likely to form ionic bonds.

Hydrogen Bonds

Option d) states that atoms with filled outer electron shells form hydrogen bonds. However, this is not accurate. Hydrogen bonds are a type of intermolecular force that arises between molecules that have a hydrogen atom bonded to a highly electronegative atom, such as oxygen, nitrogen, or fluorine. Atoms with filled outer electron shells do not have a strong tendency to form hydrogen bonds.

The Correct Answer

The correct answer is a) are particularly stable and non-reactive. Atoms with filled outer electron shells are indeed particularly stable and non-reactive, as they have already achieved a stable configuration and do not have a strong tendency to gain or lose electrons.

Conclusion

In conclusion, atoms with filled outer electron shells are particularly stable and non-reactive. They do not have a strong tendency to gain or lose electrons, making them less reactive. While they may participate in some chemical reactions, they are not likely to form covalent bonds, ionic bonds, or hydrogen bonds in aqueous solutions.

Key Takeaways

Atoms with filled outer electron shells are particularly stable and non-reactive.
They do not have a strong tendency to gain or lose electrons.
They are less likely to form covalent bonds, ionic bonds, or hydrogen bonds in aqueous solutions.

Q: What is the significance of filled outer electron shells in atoms?

A: Atoms with filled outer electron shells are particularly stable and non-reactive. This is because the outermost energy level, also known as the valence shell, is completely filled with electrons. As a result, these atoms do not have a strong tendency to gain or lose electrons, which makes them less reactive.

Q: What is the octet rule, and how does it relate to filled outer electron shells?

A: The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer energy level, which typically consists of eight electrons. Atoms with filled outer electron shells have already achieved this stable configuration, making them less likely to participate in chemical reactions.

Q: Can atoms with filled outer electron shells form covalent bonds?

A: No, atoms with filled outer electron shells are not likely to form covalent bonds. Covalent bonds are typically formed between atoms that share one or more pairs of electrons to achieve a stable configuration. Atoms with filled outer electron shells do not have a strong tendency to share electrons.

Q: Can atoms with filled outer electron shells form ionic bonds?

A: No, atoms with filled outer electron shells are not likely to form ionic bonds. Ionic bonds are formed between atoms that have a strong tendency to gain or lose electrons, resulting in the formation of ions with opposite charges. Atoms with filled outer electron shells do not have a strong tendency to gain or lose electrons.

Q: Can atoms with filled outer electron shells form hydrogen bonds?

A: No, atoms with filled outer electron shells are not likely to form hydrogen bonds. Hydrogen bonds are a type of intermolecular force that arises between molecules that have a hydrogen atom bonded to a highly electronegative atom, such as oxygen, nitrogen, or fluorine. Atoms with filled outer electron shells do not have a strong tendency to form hydrogen bonds.
