Sodium would most like be the element with one more electron over neon.
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.
with some Styrofoam balls glue them together and add ten protons/electron and ten neutrons
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.
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.
Yes, the electron arrangement in a sodium ion (Na+) is similar to neon. Both ions have a stable electron configuration with a full outer energy level (valence shell), making them inert and unreactive. Sodium loses one electron to achieve the same electron configuration as neon.
If a sodium atom loses an electron to become a Na+ ion, its electron configuration will be the same as neon (1s22s22p6). Both sodium and neon have stable electron configurations.
2, 8 is the electron configuration
When you move from neon to sodium, the electron count increases from 10 to 11, as sodium has one more electron than neon. This additional electron occupies the third energy level orbital, resulting in an additional shell being added for sodium compared to neon.
When aluminum (Al, #13) reacts, it loses its three valence electrons to achieve the same electron configuration as neon (Ne, #10.) That configuration is 1s22s22p6. So yes, Al+3 has the same configuration as neon.
.. :Ne: ``
Na+ and neon are isoelectronic.
Magnesium will lose 2 electrons to have the same electron configuration as Neon. Neon has a full valence shell with 8 electrons, and Magnesium has 2 valence electrons. By losing 2 electrons, Magnesium can achieve a full valence shell and the same electron configuration as Neon.
