Question

What is the octet rule?Would it be possible for an atom to achieve more than eight valence electrons?

Answer 1

Answer:

Explanation:

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.

Some molecules can accommodate more than 8 valence electrons because they have expanded valence shells. These molecules are from periods 3 or higher because starting from n=3, atoms have d-orbitals that can accommodate for more that 9 valence electrons.

Answer 2

The octet rule states that when an atom's valence shell is full with eight electrons, it is the most stable. Yes, it's possible for an atom to achieve more than eight valence electrons.

• As per the octet rule , the atom is in its most stable state when the valence shell is completely occupied with eight electrons.
• Yes, it's possible for an atom to achieve more than eight valence electrons because of their extended valence shells.
• The atoms belonging to period one and two can only have s and p orbitals that is total of 8 electrons in their valence shell. But apart from them some other elements have the ability to occupy more than 8 electrons because of the presence of d orbital. Some examples are SF6 and PCl5.
