Answer: Option (A) is the correct answer.
Explanation:
A phenomenon where delocalization of pi electrons or non-bonding electrons takes place is known as resonance.
For example, in a 
molecule two oxygen atoms contain -1 charge. And, delocalization of pi electrons takes place in order to attain stability.
When in a molecule, there occurs unequal sharing of bonding electrons by a chain of atoms then there occurs a permanent dipole moment. And, this effect is known as inductive effect.
So, basically more difference in electronegativity of the atoms in a molecule tend to cause inductive effect.
In , there is not much difference in the electronegativity of carbon and oxygen atom.
Hence, resonance effect predominates inductive effect.
Potential energy is the energy obtained by an object due to its position.
Thus, we can conclude that the ion is stabilized by resonance.
Answer:
The element iodine forms an anion with the charge -1. The symbol for this ion is I⁻¹, and the name is iodide. The number of electrons in this ion is 7.
Explanation:
Hello,
In this case, we have to consider iodine has the capacity to accept the electrons lost by other elements such as metals or hydrogen by becoming negatively charged. Such phenomena makes iodine to form an anion (negatively charged) with the charge -1, since it only needs one electron to attain the octet. Moreover, the symbol of such ion is I⁻¹ and its name is iodide. By cause of the aforementioned, the number of electrons it has is 7 since at its outer shell seven electrons are found (see electron configuration Kr,5s²,5p⁵).
Best regards.
It plays a key role in shaping ecosystems by serving as an agent of renewal and change. But fire can be deadly, destroying homes, wildlife habitat and timber, and polluting the air with emissions harmful to human health. Fire also releases carbon dioxide a key greenhouse gas into the atmosphere
Yes; every object has energy and you cannot create or destroy energy but you can transfer it.
