Hund's Rule<span>. </span>Hund's rule<span>: every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin. so D. is the answer</span>
A covalent bond is formed.
Answer:
That the isotope H-1 is the most abundant in nature.
Explanation:
Hello!
In this case, since the average atomic mass of an element is computed considering the mass of each isotope and the percent abundance each, for hydrogen we would set up something like this:
Moreover, since the isotope notation H-1 and H-2 means that the atomic mass of H-1 is 1 amu, that of H-2 is 2 amu and the average one is 1.0079 amu, we can infer that the most of the hydrogen in nature is H-1 as the most of it composes the average hydrogen atom.
Best regards!
Answer:
1s² 2s² 2p⁶ 3s² 3p⁴
Explanation:
Looking at the <em>periodic table</em>, we see that sulfur (S) has an atomic number of 16, this means its electronic configuration would be:
We know the electronic configuration written above is correct because the sum of all the superscript numbers is 16 (2+2+6+3+4=16).
