The symbiol depends on the type of noble gas. So its not constant. It may be positive or even negative.
Transition metals such as copper, silver, and gold can form ions with a noble gas electron configuration. This occurs when they lose electrons to achieve a stable electron configuration similar to the nearest noble gas.
The stable ions of all the elements except the Transition metals, Actinide, and Lanthanide series (that is the d and f block elements) form stable ions that are isoelectronic to a nobel gas by gaining or losing electrons in order to achieve an s2 p6 stable octet. For example, sodium will lose one electron to have the same electron configuration as neon, while nitrogen will gain three electrons to become isoelectronic to neon.
Chemical properties depend on electron configuration. By either gaining or losing electrons, an atom changes its electron configuration and therefore its chemical properties also change.The atoms of an element will react to achieve a noble-gas configuration. The atoms will either gain or lose electrons to achieve such a configuration.
Rb is likely to adopt a noble gas configuration of [Kr] when it forms ions. This means it will lose one electron to achieve a stable octet configuration, similar to the nearest noble gas element, krypton.
Ions derived from representative elements achieve stability by gaining or losing electrons to achieve a full outer electron shell. For example, Group 1 elements tend to form +1 ions by losing one electron to achieve a noble gas configuration, while Group 17 elements tend to form -1 ions by gaining one electron. This process allows the ions to attain a more stable electron configuration similar to that of a noble gas.

Alkali earth metals typically form +2 ions when they lose two electrons to achieve a stable electron configuration (noble gas configuration).

All the elements in their normal state are reactive and unstable. In order to attain stability i.e. a state of minimum energy, they tend to form ions by loosing or gaining electrons. By doing so, they achieve stable electronic configuration or noble gas configuration. However, some elements do not form ions. Instead of that, two such atoms share electrons with each other and achieve this noble gas configuration. At the end, the main reason for attaining a noble gas configuration is to attain max. stability and min. energy.
yes
Atoms that are close to achieving a noble gas configuration through the gain or loss of a few electrons are most likely to share electrons to achieve a noble gas configuration. These are usually atoms in groups 14-17 of the periodic table, such as carbon, nitrogen, oxygen, and fluorine. They form covalent bonds through electron sharing to achieve stability.
Cs does not have a nobel gas electron configuration, as it contains one valence electron in its outermost s orbital. Be3+ also does have a nobel gas electron configuration, as this occurs when Be has a 2+ charge (the typical Be ion is Be2+).
metals lose electrons to form ions so as to obtain noble gas configuration. for e.g. sodium(Na) has 11 electrons i.e. 1 electron in its valent (last) shell, to attain noble gas configuration sodium loses 1 electron which may be gained by a non-metal to stabilize itself.
Cl- and Ca2+ has the electronic configuration of the noble gas, Ar, with 18 electrons.
