The highest energy electron in uranium is found in the 5f subshell. Uranium has 92 electrons, so the configuration for the highest energy electron would be [Rn] 5f³ 6d¹ 7s².
Gamma, as it has the most energy by far.
The lower case letter in the symbol represents the subshell that the electron is in. It is a way to indicate the energy level and shape of the electron's orbit. Upper case letters are used for the element's name, while lower case letters are used for subshell designation.
The three components are (i) the principle energy level (n), (ii) the subshell and (iii) the number of electrons. Hydrogen would be 1s1 where n is 1, subshell is s and number of electrons is 1.
The 4f subshell has higher energy compared to the 4s, 4p, and 4d subshells. This is due to the increased screening effect and poor shielding of the nuclear charge by intervening 4d and 4p electrons. The 4f subshell is further away from the nucleus, leading to higher energy levels.
Transfer of an electron from a higher energy orbit (2s) to a lower energy orbit (1s) is not possible because it would violate the energy conservation principle. Electrons naturally occupy the lowest available energy levels in an atom, following the Aufbau principle. This means electrons will only move to higher energy levels if they absorb energy, not by transferring between lower and higher energy levels.

The principal quantum number (n) distinguishes between different subshells. For example, the 1s subshell has an n value of 1, while the 3s subshell has an n value of 3. The higher the n value, the higher the energy level of the subshell.
The element with its outermost electron in the 7s1 orbital is francium (element 87). Its outermost electron is in the 7th energy level (n=7), specifically in the 7s subshell.
Elements in Group 4 end their electron configurations with 4s2 4p2. This is because they have 4 valence electrons, with the last two electrons occupying the s-subshell (4s) and the p-subshell (4p) completing the outermost energy level.
Gamma, as it has the most energy by far.
The electron in the same subshell with the highest principal quantum number will experience the greatest effective nuclear charge in a many-electron atom, as it will be closest to the nucleus. Additionally, electrons in higher energy levels (with higher n values) experience less effective nuclear charge due to shielding effects from inner electrons.
The lower case letter in the symbol represents the subshell that the electron is in. It is a way to indicate the energy level and shape of the electron's orbit. Upper case letters are used for the element's name, while lower case letters are used for subshell designation.
The electron in the outermost shell will emit the greatest amount of energy when dropping electron levels because it has the highest energy level. Electrons in higher energy levels have more energy to release when transitioning to lower energy levels.
An element with the electron configuration Ne3s^23p^5 is in period 3 of the periodic table. The electron configuration indicates that the element has 3 energy levels, with the last electron being in the 3p subshell.
The three components are (i) the principle energy level (n), (ii) the subshell and (iii) the number of electrons. Hydrogen would be 1s1 where n is 1, subshell is s and number of electrons is 1.
The 4f subshell has higher energy compared to the 4s, 4p, and 4d subshells. This is due to the increased screening effect and poor shielding of the nuclear charge by intervening 4d and 4p electrons. The 4f subshell is further away from the nucleus, leading to higher energy levels.
