Answer:
ii) the energy of the electron on the outer shell
iv) the overall size of an orbital
Explanation:
There are four quantum numbers to define the position and energy level of an electron in an atom
a) Principal : The principal quantum number (n) is to know the energy of an electron in an atom and its possible distance from the nucleus.
b) Azimuthal: It refers to the shape of the subshell or orbital of the electron and thus the angular distribution.
c) Magnetic: It refers to the number of orbits and their orientation in the subshell.
d) spin: It refers to the spin of the electron.
Explanation:
The teacher is most likely talking about the fractional distillation process.
Fractional distillation: It is a separation technique used to separate different components of the given mixture on the basis of their difference in boiling points of the different components. The component with lowest boiling point will get separate out first from the mixture and the vapors formed from boiling are condensed in a separate container.
So, when the fractional distillation of mixture of oils and fuels is carried out gasoline will separate out first due to lower boiling temperature and then kerosene followed by diesel and others (fuels and oils).
Answer:
Bivalve, (class Bivalvia), any of more than 15,000 species of clams, oysters, mussels, scallops, and other members of the phylum Mollusca characterized by a shell that is divided from front to back into left and right valves. ...
