Explanation: I just took the test
Answer:
B. Hund's rule
Explanation:
Hund's rule -
According to Hund's rule ,
As, the electrons are negatively charged and hence , like poles repel , so they repel each other in order to stabilizes themselves and hence , the electron firstly occupies a vacant orbital , before actually pairing up , so as to reduce repulsion .
The rule of maximum multiplicity states that ,
The term with the lowest energy is the one with the highest value of the spin multiplicity .
hence , the statement given in the question is about Hund's rule .
There is nothing conserved<span> in this reaction. When writing a β </span>equation<span>, remember that in the nucleus, a neutron ( n ) decays into a proton ( p+ ) and a high energy electron which is known as the beta ( β ) particle. Because a new proton has formed, the atomic number of the original atom will increase by 1</span>
Answer:
Electrons repel each other due to electrostatic force of attraction between both of them as a result prevent the electron from entering the nucleus preventing it from collapsing
