soln,

here first term(a)= -2

second term (t2) = 1

common difference (d) = t2 - a

= 1 +2 = 3

now,

nth term = a + (n-1)d

= -2 + ( n - 1) 3

= -2 + 3n - 3

= 3n - 5

Hund’s rule of maximum multiplicity specifies that _____. A. electrons will fill orbitals of lower energy first, pairing up only

djverab [1.8K]

Answer:

A. electrons will fill orbitals of lower energy first, paring up only after each orbital of the same energy already has one electron

Step-by-step explanation:

The rule states that for a given electron configuration, the lowest energy term is the one with the greatest value of spin multiplicity. This implies that if two or more orbitals of equal energy are available, electrons will occupy them singly before filling them in pairs.
