Question

Elements are unstable in free state except noble gases. Explain how elements attain stability?​

Answer 1

Radiation is emitted from atoms when an unstable atom decays to become more stable. When an atom has extra neutrons or protons, it causes the element to become unstable. This activity helps students understand how emitting an alpha or beta particle changes the structure of an atom.

Answer 2

Answer:

Explanation:

Atoms attain stability by completing their octet or duplet. They gain or lose electrons to attain stability. They obey octet or duplet rule. Either they tend to acquire two electrons in their valence shell or they tend to acquire eight electrons in their valence shell to attain stability
