It can be.
An ion is an atom with more or less electrons than protons.
But having 8 valence electrons (simply) means it has a full outer shell.
But the noble gases already have a full shell without being an ion.
The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.
No, not all elements except noble gases form ions. Noble gases are considered inert because they have a complete outer electron shell, making them stable and less likely to form ions. Other elements may gain or lose electrons to form ions.
The lower the the Atomic Number, the higher the Ionic Energy.
Ions are cations (positive) or anions (negative).
Elements in Group 1 (alkali metals) readily form ions by losing one electron to achieve a stable electron configuration. This is due to their low ionization energy, which makes it easier for them to lose electrons and form positively charged ions.

We haven't seen your graph. However, it is easy to say what kinds of ions elements form. Metals form positive ions and nonmetals form negative ions.
The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.
Elements in group 1, also known as the alkali metals, typically form ions with a +1 charge by losing one electron. This is because they have one electron in their outermost energy level, making it easier for them to lose that electron to achieve a stable electronic configuration.
Noble gases doesn't form ions.
Chloride ions would form elements with ions of metallic elements. For example, with sodium ions, chloride ions form sodium chloride.
Nonmetals typically form negative ions by gaining electrons to achieve a stable electron configuration. For example, fluorine, chlorine, and oxygen commonly form negative ions by gaining one or more electrons.
cations = positively charged ions
lose 2 electrons and form ions with a 2+ charge.
No, not all elements except noble gases form ions. Noble gases are considered inert because they have a complete outer electron shell, making them stable and less likely to form ions. Other elements may gain or lose electrons to form ions.
Generally this is a characteristic of the metallic elements.
