Guida verificata passo dopo passo1
Recall that the octet rule states atoms tend to have 8 electrons in their valence shell to achieve stability.
Identify the number of valence electrons oxygen has, which is 6 according to the problem statement.
Determine how many more electrons oxygen needs to reach 8 by subtracting its current valence electrons from 8: \(8 - 6\).
Calculate the difference to find the number of additional electrons required for oxygen to complete its octet.
Conclude that oxygen needs 2 more electrons to achieve a stable octet configuration.
