The electron arrangement in a sodium ion (Na+) is similar to neon, as both have a full outer electron shell. Sodium loses one electron to achieve the stable electron configuration of neon (2,8). Argon has a full outer shell with 8 electrons, making it different from both sodium and neon.
Argon has the same electron configuration as a sodium ion. Sodium ion has lost 1 electron from its outer shell, making its electronic configuration 2, 8. Argon's electronic configuration is also 2, 8 in its outer shell.
Sodium is more reactive than neon. Neon is part of the noble gases group, which are generally unreactive due to their stable electron configuration. In contrast, sodium belongs to the alkali metal group, which are known for their high reactivity due to their tendency to lose an electron to achieve a stable electron configuration.
Argon has the same electron configuration as the oxide ion, O2-. Both have a stable electronic configuration with a full valence shell of electrons.
Aluminium (Al3+) has a similar electron configuration to the noble gas neon (Ne). Both Al3+ and Ne have a full outer electron shell, making them stable and unreactive.
The electron arrangement in a sodium ion (Na+) is similar to neon, as both have a full outer electron shell. Sodium loses one electron to achieve the stable electron configuration of neon (2,8). Argon has a full outer shell with 8 electrons, making it different from both sodium and neon.
Na+ and neon are isoelectronic.
Argon
The stable electron arrangement of sodium after the 3s sublevel electrons have been removed is the noble gas configuration of neon. Sodium loses one electron to achieve a full outer shell, similar to the electron configuration of the nearest noble gas element.
In sodium fluoride, sodium has the electron configuration of neon. Sodium has an electron configuration of 2-8-1, similar to neon which has a full outer electron shell.
The electron arrangement in an ion of chlorine will be similar to argon because both chlorine (Cl) and argon (Ar) are in the same period (row) of the periodic table. Neon (Ne) is in a different period and has a different electron arrangement.
To achieve the same electron arrangement as neon, potassium would need to lose one electron, since neon has a full valence shell with 8 electrons. This would leave potassium with a stable electron configuration similar to neon.
Argon has the same electron configuration as a sodium ion. Sodium ion has lost 1 electron from its outer shell, making its electronic configuration 2, 8. Argon's electronic configuration is also 2, 8 in its outer shell.
neon only because sodium loses an electron an its outer shell becomes empty making its configuration the same as neon and fluorine gains an electron making its configuration the same as neon as well.
The electron configuration of the sodium ion (Na+) becomes similar to that of neon (Ne), while the electron configuration of the fluoride ion (F-) becomes similar to that of a noble gas like argon (Ar). This is achieved through the transfer of one electron from sodium to fluorine during the formation of NaF.
Chlorine needs to gain one electron to achieve the same electron arrangement as neon, which has a stable octet (eight valence electrons). By gaining one electron, chlorine will have a full outer shell with eight electrons, resembling the electron arrangement of neon.
Sodium wants to lose one electron to achieve a stable electron configuration, similar to the noble gas neon.
