Those elements are called transition elements
Elements with only five electrons in the p sublevel belong to Group 15 or the Nitrogen family on the periodic table. This group includes elements like nitrogen, phosphorus, arsenic, antimony, and bismuth.
In the fifth period of the periodic table, the atoms of the elements in the first two groups are adding 1 and 2 electrons, respectively, to their highest energy 5s sublevel. Starting in group 3/IIIB and going through group 12/IIB, the atoms of those elements are adding electrons to their highest energy 4d sublevel. Since the d sublevel can contain a maxium of 10 electrons, there are 10 elements whose atoms are filling the 4d sublevel. Once the 4d sublevel is filled, the next higher energy sublevel is the 5p sublevel. Starting with the group 13/IIIA elements, the 5p sublevel is being filled. Since a p sublevel can contain a maximum of 6 electrons, there are six elements whose atoms are filling the 5p sublevel. 5s sublevel filling: 2 elements 4d sublevel filling: 10 elements 5p sublevel filling: 6 elements --------------------------------------- Total: 18 elements For a printable periodic table that includes electron configurations, go to the following link: http://www.nist.gov/pml/data/periodic.cfm
The energy sublevel being filled by the elements Rb (rubidium) to Sr (strontium) is the 5s sublevel. These elements are in the fifth period of the periodic table, and in period 5, the s sublevel starts to fill up with electrons.
The 2s sublevel can hold a maximum of 2 electrons.
The elements that have 2 electrons in the 4s sublevel are calcium (Ca) and scandium (Sc).

The energy sublevel being filled by the elements Rb (rubidium) to Sr (strontium) is the 5s sublevel. These elements are in the fifth period of the periodic table, and in period 5, the s sublevel starts to fill up with electrons.
The 2s sublevel can hold a maximum of 2 electrons.
The elements that have 2 electrons in the 4s sublevel are calcium (Ca) and scandium (Sc).
The energy sublevel being filled by the elements Ce to Lu is the 4f sublevel. These elements are part of the lanthanide series and have their outermost electrons entering the 4f orbital.
Transition elements can lose electrons from their d sublevel when they react chemically. This is because the d sublevel contains the valence electrons involved in bonding for transition elements.
The elements Yttrium (Y) and Cadmium (Cd) fill the 4d energy sublevel.
Transition elements typically fill the 3d and 4s sublevels across the periodic table. As you move across the transition elements from left to right, electrons are added to the 3d sublevel until it is full, before filling the 4s sublevel.
The element with its outermost electrons in an S sublevel is found in Group 1 and Group 2 of the periodic table. These elements have their outermost electrons in the S sublevel before transitioning to the D sublevel in subsequent groups.

The highest sublevel that Promethium can have is 4f. It is possible for 14 electrons to be placed around Promethium, since the elements in this sublevel each have 7 orbitals.
