Rubidium
Rhenium, with atomic number 75, has two electrons in its fifth energy level.
The element in the fifth period of the periodic table that requires only one more electron to complete its outermost energy level is rubidium (Rb). It has one electron in its outermost shell (5s¹) and needs one additional electron to achieve a stable electron configuration, similar to that of xenon, the nearest noble gas.
When the higher principal energy level of a period 4 element is 5, it indicates that the element is in the fifth energy level of its electron configuration. However, period 4 elements actually have principal energy levels ranging from 1 to 4, with the outermost electrons occupying the 4th energy level. Therefore, if an element in period 4 is said to have a principal energy level of 5, it is likely being referred to in the context of its ionization states or when discussing higher energy states after electron excitation. Elements in period 4 include transition metals which can have variable oxidation states, influencing their electron configurations in different states.
For fermium: 30 electrons.
"Life" was the fifth element...
The fifth electron shell, also known as the fifth energy level or n=5, can hold a maximum of 50 electrons. This is calculated using the formula 2n^2, where n is the principal quantum number.
The energy of the electron in a hydrogen atom in an excited state of 5s1 is higher than in the ground state. This is due to the electron being in a higher energy level, specifically the 5s orbital. The configuration of the electron in this excited state indicates that it is in the fifth energy level and occupies the s subshell.
The element in the fifth period with the highest ionization energy is xenon. Ionization energy generally increases across a period from left to right, so xenon, being on the far right of the period, has the highest ionization energy.
