Hund's rule states that when a sublevel contains several orbitals of equal energy, electron(s) must be placed in each orbital before electrons are <u>paired.</u>
<u />
According to Hund's rule, each orbital within a sublevel is always singly occupied before it becomes double occupied. Every electron in solely filled orbitals possesses the same spin.
Only when every orbital in a sublevel has one electron would electrons pair up inside an orbital. They are all the same spin whenever a single electron is present in many orbitals within the same sublevel.
Therefore, Hund's rule states that when a sublevel contains several orbitals of equal energy, electron must be placed in each orbital before electrons are <u>paired.</u>

The correct answer would be C. Convection, which describes that heat rises.
Nuclear explosion i hope that correct
Noble gases belong to group 18 of the periodic table. These elements are inert because they have their valence orbital shells as ‘full’ hence do not participate in reactions since they cannot share electrons. These elements have a pattern in their electron configuration. Their outer most orbital shells has 8 electrons (with the exception of 2 for helium).
If we remove 2 electrons, the new charge will be positive by 2 units. Hence, the ion is
