<p>30 outer electrons in stead of 29 electrons in the PTE. </p>
<p>When considering that there is one missing noble gas before Copper, the number of 30 outer electron is likely correct.</p>
<p>The nuclet ending is essentially the same as Oxygen. Further research is needed to make proper correlations. </p>
<p>Note: It seems that the more outer electrons are 'bound' to the inner part of the nucleus (the so called extra neutrons in relation to the number of protons), the more positive the elements become, meaning a incomplete neon state such as Oxygen becomes in copper positive, Oxygen is not bothered by this and remains its 'negative' nature. We see this with all elements. The transition lies at about Phosphorus where it can be either negative or positive.</p>
