Did you mean "why do the arrows point in different directions?" if so, the answer is that, since electrons are both negatively charged, the will repel from each other, causing one to go in one direction, and the other opposite that. Think "Pauli exclusion principle" which states "no two electrons in the same atom can be in the same quantum state." This 'state' includes spin, and the arrows represent the spin of the electron orbit.
I hope this helped!

Assuming K stands for potassium, an element with 19 electrons, the electron configuration is as follows: 1s2 2s2 2p6 3s13p64s1 The electron configuration shows the orbitals is order of energy level. The 4s orbital being at the highest energy level and the 1s orbital being at the lowest energy level. As 2px, 2py and 2pz exist, there are three 2p orbitals that occur at the p level, allowing the element to carry 6 electrons, 2 in each orbital. There is a specific order in listing the orbitals

The most important principle was the listing in groups, after similar chemical or physical properties.
It's a table listing the elements, organized in columns of similar types of elements with respect to their chemical bonding characteristics, based on their atomic numbers and electron configurations.
There is no opposite of itemize (list, detail) except the choice not to itemize. - On US income tax returns the opposite of listing itemized deductions is taking a standard deduction.) - The opposite of listing itemized expenses is to list a total or estimated total.
