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.
A Scottish scientist Graham, Thomas formulated Graham's law of effusion or simply Graham's law. This law states that rate of gas 1 over gas 2 is equal to the square root of the molar mass of gas 2 over <span>he square root of the molar mass of gas 1. Since the molar mass of Neon is 4, the answer is then 8.16 g/mol</span>
It consists of three adjacent structural genes, a promoter, a terminator, and an operator. The lacoperon<span> is regulated by several factors including the availability of glucose and lactose. It can be activated by allolactose. Lactose binds to the repressor protein and prevents it from repressing gene transcription.</span>
