Atoms of the element sodium (atomic number 11) have the electron configuration 1s22s22p63s1
with the noble gas form [Ne]3s1
Sodium: [Ne] 3s1
Oxygen: [He] 2s2 2p6
It simpliy is [1s2, 2s2 2p6] 3s0 for Na+ , because noble gas Neon is [1s2, 2s2 2p6] and elemental Sodium (alkali metal) is [1s2, 2s2 2p6] 3s1
[He]2s2 2p4
[Ne]3s1
[Ne] 3s1.
The element chlorine does not have noble gas configuration. But chloride ion formed (when chlorine accepts an electron) has noble gas configuration of argon.
P3- ion or phosphide ion as the same electron configuration as the noble gas, argon
Neon
The charge of a sulfide ion that is isoelectric with its nearest noble gas (argon) is -2. This means that the sulfide ion has gained two electrons in order to have the same electron configuration as the noble gas.
The noble gas (electron) configuration is a scheme for writing the electron configurations of elements in a kind of "shorthand" so it is easier to write them. For potassium element - not ion , [Ar] 4s1 is the way it is written in noble gas configuration. If we could not use this shorthand and had to write out the electron configuration completely, it would like this:1s2 2s2 2p6 3s2 3p6 4s1Wikipedia has other information on potassium, and a link is provided.For Sodium it is [Ne]3s1 and thus for sodium ion it is just [Ne]
Sodium looses one electron to achieve noble gas electronic configuration.The formula of ion formed is Na+
Sodium ion (Na+) and neon will have the same number of electrons
Sodium looses one electron to achieve noble gas electronic configuration.The formula of ion formed is Na+
Sodium and magnesium form positive ions because they lose electrons in order to have a filled valence shell, like a noble gas. A sodium atom loses one electron so that its ion has a 1+ charge and the noble gas configuration of neon. A magnesium atom loses two electrons so that its ion has a charge of 2+ and the noble gas configuration of neon.
Sodium atom has 11 electrons...whereas sodium ion has 10 electrons. Sodium ion is more stable because it has a complete octet(noble gas configuration-Neon) which makes it inert like noble gas. Sodium atom tends to lose the extra electron which is in 3-s shell to become stable.
The element chlorine does not have noble gas configuration. But chloride ion formed (when chlorine accepts an electron) has noble gas configuration of argon.

No, Na is sodium, an alkali metal. The noble gasses are in the far right column of the periodic table.
P 3- is the ion with the noble gas configuration.
