4 Questions
Why do Group VIA elements try to gain two electrons during chemical changes?
To form di negative anions
Which statement is true about Group VIIIA elements like neon?
They are highly stable and rarely participate in chemical changes
Why do helium and neon not participate in chemical changes?
Because they already possess eight electrons in the valence shell
What makes any species (atom or ion) with eight electrons in the valence shell stable?
Achieving stability through a full valence shell
Study Notes
Noble Gases
- Group VIA elements (e.g., oxygen, sulfur) try to gain two electrons during chemical changes to achieve a full outer energy level, which is a stable configuration similar to that of noble gases.
Noble Gases Characteristics
- Group VIIIA elements (noble gases) like neon are unreactive because they have a full outer energy level, which makes them stable and prevents them from reacting with other elements.
Non-Reactivity of Helium and Neon
- Helium and neon do not participate in chemical changes because they have a full outer energy level, which makes them extremely stable and unreactive.
Stability of Octet Configuration
- A species (atom or ion) with eight electrons in the valence shell is stable due to its full outer energy level, which is a configuration similar to that of noble gases.
Test your knowledge on the concept of group VIA and group VIIA elements in chemistry, focusing on their electron gain and formation of corresponding anions. This quiz provides examples and explanations to help reinforce your understanding.
