The general electron configuration of the group having the lowest ionization energy is [Noble gas configuration]xs1. In this case, x is the principal quantum number of the valance electron. The noble gas configuration may either be written out in full or denoted by the noble gas' atomic symbol in brackets (ie [Ne]).

What is the longhand electronic configuration of uranium?
The electron configuration of uranium is: 1s22s2p63s2p6d104s2p6d10f145s2p6d10f36s2p6d17s2
Why is the second ionisation energy of Na much greater than the second ionisation energy of Mg?
The second ionization energy of sodium (Na) is much greater than that of magnesium (Mg) because of the difference in their electronic configurations and the stability of the resulting ions. When Na loses its first electron, it achieves a stable noble gas configuration (Neon), making the removal of a second electron from the positively charged Na⁺ ion much more difficult. In contrast, when magnesium loses its first electron, it still has a relatively stable electron configuration and retains two valence electrons, making the second ionization less energetically demanding. Thus, the increased stability of Na⁺ compared to Mg⁺ contributes to the significantly higher second ionization energy for Na.
What is common to the electronic configuration of Li and Na?
Both lithium (Li) and sodium (Na) have one electron in their outermost energy level, giving them similar electronic configurations. They both have an electron configuration of [Ne] 3s¹, where [Ne] represents the electron configuration of the noble gas neon.
What does configuration of tin mean?
The configuration of tin refers to its electronic configuration, which is [Kr] 4d^10 5s^2 5p^2. This indicates the distribution of electrons in the energy levels of tin atoms.
How many chemical bonds in one atom of argon?
Argon is a noble gas element. It has a saturated electronic configuration i.e ns2, np6. So it has a octet configuration. It is already attained stable configuration. Also it has high ionisation energy. Small in atomic size. From the above it is confirmed that it exists in atomic state only and not is molecular form. Therefore chemical bond will be zero in an atom of argon.
Why metal has lower ionisation energy?
Because the force of attraction between the nucleus and the outer most electron is less. In addition, most metals (but not all) will gain the stable electronic configuration of the nearest noble gas if they lose electron.
Which element has the electronic configuration 2.2?
Helium (He) has the electronic configuration 2.2 since it has 2 electrons in the first energy level and 2 electrons in the second energy level.
How can you relate ionisation potential and ionisation energy?
Ionisation potential and ionisation energy are essentially the same concept - they both refer to the amount of energy required to remove an electron from an atom or molecule. The terms are often used interchangeably in practice.
What is the correct electronic configuration of magnesium Mg?
The correct electronic configuration of magnesium (Mg) is 1s^2 2s^2 2p^6 3s^2. This configuration represents the arrangement of electrons in the different energy levels and sublevels of an atom of magnesium.
How does the ionisation energy change down the groups in the periodic table?
Ionisation energy decreases down the group. It is easy to remove an electron.
What is ionisation energy What is first ionisation energy?
The first ionization energy of an atom or molecule describes the amount of energy required to remove an electron from the atom or molecule in the gaseous state.
