Use the relative size of the 3s orbital below to answer the following questions about orbitals A–D. (a) Which orbital has the highest value of n? (b) Which orbital(s) have a value of l = 1? l = 2? (c) How many other orbitals with the same value of n have the same shape as orbital B? Orbital C? (d) Which orbital has the highest energy? Lowest energy?

a) Option D

b) A and C, I = 1

B and D, I = 2

c) There are three orbitals that have the same value of n and the form as option B. there are 5 orbitals d for the values of n. Four have the same shape as option B, the fifth has the same shape as the D orbital. On the other hand, there are two orbitals with the same shape as C. Each p orbitals has the same shape. Therefore, there are two orbitals with the same value of n and the same shape as the option C orbital.

d) highest energy: D

lowest energy: C

Explanation:

a) If the value of n increases, the size of the orbital would increase, and since option D is the largest, this means that it has the highest value of n.

b) Quantum number means the number of nodes in each orbital. Since A and C are p-type orbitals, they only have a single node, therefore I = 1. Regarding B and D, they are both d orbital orbitals, and the quantum number for this type of orbital is 2, therefore I = 2

d) The energy level is directly proportional to the value n. As n increases, the energy level increases, therefore, D has the highest energy because it has the largest number of n, and C has the lowest energy because the value of n is small.

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
