Sodium would need to lose one electron in order to obtain a full and stable outer shell, however it would be an ion with a positive charge
Noble gases, such as neon or argon, are least likely to form ionic bonds with sodium since they already have a full valence shell and do not readily gain or lose electrons.
Sodium can become stable by losing 1 electron, forming a sodium ion with a 1+ charge, with the formula Na+. By losing its single valence electron, the resulting sodium ion achieves the noble gas configuration of neon, so that it has an octet (8) of valence electrons.
That is correct. A noble gas (or at least all the noble gas elements heavier than helium) has an electron configuration of 8 electrons in its outer shell, and the sodium and chlorine ions in sodium chloride also have 8 electrons in their outer shell, just like a noble gas atom.
The sodium atom will lose its outer electron to achieve stability. By losing this electron, it will have a full outer shell, like a noble gas, and become a positively charged sodium ion.
No noble gas possesses 6 electrons in the 6th energy level. Noble gases have a stable electron configuration with a full valence shell. Helium has 2 electrons in its first and only energy level, while neon has 10 electrons in its second energy level.
If the element has a full valence shell, such as the noble gases, then it is unreactive. It the element is missing few valence electrons of has few valence electrons, then the element is very reactive, such as the sodium.
A species (element, cation or anion) should have eight valence electrons to have a noble gas electronic configuration. However element upto atomic number 4 may have 2 valence electrons and attain the electronic configuration of helium noble gas.
Krypton is a noble gas with 36 electrons.
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.
Helium is the element in the noble geses family that does not have an octet. Helium is the element in the noble geses family that does not have an octet.
Neither, Sodium is an Alkali Metal.
An element can either gain or lose electrons to achieve a noble gas electron configuration. Such an electron configuration gives an atom of an element a full outer shell, thereby making that element's ion nonreactive. Metals tend to lose electrons, and become cations, whereas nonmetals tend to gain electrons, and become anions. The amount of electrons an element gains of loses is based on the group/family the element is found in on the Periodic Table.
Sodium has the configuration Ne 3s2 . Sodium is group-1 element.
To become like a noble gas, an element must have a full outer electron shell, making it stable and unreactive. Elements achieve this by gaining or losing electrons to reach a total of 8 electrons in their outer shell, like the noble gases.
The element with the noble-gas configuration Ne 3s2 is sodium (Na). Sodium has an electron configuration of 1s2 2s2 2p6 3s1, but when it loses one electron, it attains the stable electron configuration of neon by having 2 electrons in the 3s orbital.
helium
It has 7 valence electrons, so needs 1 more to become noble.
