Sulfur must lose six electrons to attain noble gas electron configuration (in SO3, H2SO4 etc) but in most of the compounds it will exist as sulphides which is formed when sulphur will gain two electrons.
It should lose 1 electron and form Na+ ion.
Sodium has 11 electrons, and one valence electron To achieve noble gas configurations, it would have to gain 7 electrons, for a total of 18 like Argon has. But this gain is impossible. So Sodium loses one electron to look like Neon which has 10.
Calcium has to lose 2 electrons to form noble gas configuration.
To attain the noble gas configuration, Ca would have to lose 2 electrons, Mg would have to lose 2 electrons, Ba would have to lose 2 electrons, and Be would have to lose 2 electrons.
Sodium is atomic number 11 so it has 11 electrons. The electronic configuration would be 1s2 2s2 2p6 3s1.
Magnesium has an atomic number of 12, which means it has 12 electrons. To achieve a noble gas configuration, magnesium would need to lose both of its valence electrons. This can be achieved through chemical reactions, where magnesium can form ionic compounds by transferring its electrons to other elements, such as oxygen or chlorine.
Sodium ion (Na+) and neon will have the same number of electrons

Atoms become ions by gaining or losing electrons to achieve a noble gas configuration of electrons, which is stable. Argon already has such a configuration and is very stable as it is. Any gain or loss of electrons would make it less stable.
Sodium, like other metals, does not gain electrons, it loses electrons. Normally a sodium atom would lose only one electron in order to reach a stable electron configuration, becoming the Na+1 ion.
The properties of sodium are a result of its configuration of valence shell electrons, so for similar properties, you would look for elements with a similar configuration. Since sodium has one electron in its valence shell (which is one more electron than the previous noble gas, neon), you would look for other elements that also have one more electron than the previous noble gas. The elements in the far left column of the periodic table fit this description. This column includes the elements potassium and lithium.
That would be the elements in group 13 from boron to indium.
It needs to lose to in order to have the same number of outer electrons as Argon. The Noble gas configuration of [Ar]4s2 confirms this.
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]
