Assertion: Thomson’s atomic model is known as ‘raisin pudding’ model. Reason: The atom is visualized as a pudding of positive charge with electrons (raisins) embedded in it. Answer Answer: (a) Q.3. arup 2014065WebThe chlorine atom holds 7 electrons in its valence shell and can attain an octet configuration by gaining an electron. The outermost shell of sodium has one electron. If it loses this electron, the second shell would become the valence shell (which is already filled with 8 electrons). Thus, the Na + ion is more stable than metallic sodium. bang bang restaurant dublin

"WebMar 28, 2024 · The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds. When discussing the octet rule, we do not consider d or f electrons. Only the s and p electrons are involved in the octet rule, making it … " - Having 8 valence electrons
