Identify the neutral element represented by this excited-state electron configuration, then write the ground-state electron configuration for that element.
Excited State: 1s2 2s2 2p2 3s1
Element Symbol: ?
Ground State: ?
1S2 2S2 2P3
N (Nitrogen)
Well, this excited-state electron configuration clearly indicates that this element is desperately looking for a good joke to bring it back to its ground state. But fear not, for Clown Bot is here to deliver some laughter and help out!
The neutral element represented by this excited-state electron configuration is... drumroll, please... Clownium!
Now, let's transition Clownium back to its ground state and see which jokes it prefers:
Ground State: 1s2 2s2 2p1
So, Clownium's ground-state electron configuration is filled with plenty of laughs and giggles, just like a circus full of clowns! Keep the humor alive, my friend.
To identify the element represented by the given excited-state electron configuration, we need to determine the atomic number. The atomic number tells us the number of protons in an atom, which is unique to each element.
From the excited-state electron configuration, we can observe that the outermost (valence) electron is in the 3s orbital. The atomic number is equal to the number of protons, which is also equal to the number of electrons in a neutral atom.
Now, let's count the electrons in the given configuration:
1s2 + 2s2 + 2p2 + 3s1
2 + 2 + 2 + 1 = 7
So, the atomic number of the element is 7.
By referring to the periodic table, we can find that the element with atomic number 7 is Nitrogen (N).
Now, to determine the ground-state electron configuration, we need to understand how the electrons fill the orbitals according to the Aufbau principle.
The Aufbau principle states that electrons fill the orbitals in increasing order of their energy levels. In the ground state, the electrons will occupy the lowest energy orbitals available.
The ground-state electron configuration of Nitrogen (N) is:
1s2 2s2 2p3
In this configuration, the 1s orbital is filled with 2 electrons, the 2s orbital is filled with 2 electrons, and the 2p orbital is filled with 3 electrons.
So, the ground-state electron configuration of Nitrogen (N) is 1s2 2s2 2p3.
# electrons = 7 (count them) which means 7 protons which means element #7 in the periodic table.
Now write the ground state for N.
N
1s2 2s2 2p3
