What is the expected ground-state electron configuration of the recently discovered element with Z = 116?

Accepted Answer

Hello everyone today. We have the following problem provide the complete electron configuration of Nyoni um which has an atomic number of 113. A newly discovered element. So first let's take down some notes here, we have the atomic number for our new Tony um which is 113 since it's neutral. This means that it's going to have 113 electrons and it is also Going to be somewhere in the 7th period or the 7th row of our periodic table. And so let's also make note of some of our special orbital's more specifically our S our P and our D orbital. So s orbital can hold a maximum And holds a maximum of two electrons are P. orbital holds a maximum of six electrons and R.D. holds a maximum of 10 electrons. With those numbers in mind, we must then look at the noble gas That comes before the 7th period. That's going to be Reagan. So if we use that rate on for electron configuration, we're going to have electrons left to distribute. So if we start with our raid on R N first, we have to fill up our s orbital and we're in the seventh period. So that's going to be seven S two more. So We can't just fill up our P&R. D orbital's though. Because if we do that, that will not amount to just 27. So what we have to do is we have to go into our f orbital in our f orbital holds a maximum of 14 electrons. So once we have our seven S two, we must dip into our five f orbital. So f orbital's are always going to start to numbers below what R s orbit would be. So for S orbital was seven, R f orbital B five. If r s orbital was four Or if RS orbital was eight Or six, then our f orbital would be six or 4 respectively. So we have our five F 14 since we're going to fill in all of those electrons and then we move back to the D orbital and D orbital are always going to be one less than an S orbital. So this is why we have a six D and it's 10 because we're filling in all of those electrons. And lastly, we have our p orbital and we only will have one electron left. So then we go back to our seven S and P are always on the same number. That's going to be seven p and then one. And so this is going to be our complete electron configuration for NATO monium overall, I hope that this helped and until next time
