It wishes to lose 1 electron.
Metals because metals are mostly on the left side of the Periodic Table and have fewer electrons.
These elements are called ions. Elements choose to lose or gain electrons because they want to achieve electronic stability. All metals lose electrons and all non-metals gain electrons to get the respective stable electronic structure they want. As for metalloids, some elements in there gain while some lose electrons. When elements lose or gain electrons, they will form a charge, since the number of protons and neutrons are not balanced now. All non-metals form negative charged ions while all metals form positive charged ions. Compounds are formed when a positively charged ion is attracted to an negatively charged ion by the electrostatic force of attraction. For example, sodium chloride is a compound of sodium ion and chlorine ion. The positively charged sodium ion is attracted to the negatively charged chloride ion to form the compount.
Groups determine the number of electrons on the outer shell of an atom. When elements react, they want to complete their outer most shell. Filling the outer most shell is called the octet rule. In the cases of groups 1, 2 and 3, they want to donate, 1, 2 or 3 electrons to lose the outer most shell and form a completed outer shell.
Group 1 elements, such as sodium (Na) and potassium (K), want to lose exactly one electron to achieve a stable electron configuration. This makes them highly reactive as they try to achieve a full outer shell of electrons.
Elements want to gain or lose electrons in order to achieve a stable electron configuration, usually by attaining a full valence shell of electrons. This helps them achieve a more stable, lower energy state, similar to the configuration of noble gases.

No - it would want to lose these two electrons
Ions are formed when elements either gain or lose their electrons. For example, Sodium (Na), since it has one electron in its outer shell (valence electron) it will be easier for the atom to lose its one valence electron and give it to an element that would want to gain that one electron, for example, Chlorine. This reaction of gaining or losing electrons would create an either negative ion (gained electrons) or a positive ion (lost electrons). For the example that I did, the element Sodium would lose its one electron in its outer shell making it Na +1 because it would have one more positive charge then it would negative charge.

Magnesium has two valence electrons in its outer shell and typically loses these electrons to achieve a stable electron configuration, similar to that of noble gases. By losing two electrons, Magnesium becomes a positively charged ion (Mg²⁺). Therefore, Magnesium wants to lose 2 electrons rather than gain any.

Having just 18 electrons make Calcium nobel.
These with a positive charge.
It wants one.
This seems more like a statement of fact than a question. In any case, the statement is half true. Chlorine tends to take electrons, while Sodium tends to lose them. The reason (which is what I suspect you want to find out) is that the electron configurations for Sodium and Chlorine atoms are very unstable. (Sodium Chloride is a compound while Sodium and Chlorine are the elements that make up the compound. When referring to them separately, please use the correct terminology.) Sodium has a lone valence electron, sitting all alone in the outermost orbital of the atom. Atoms will generally try to achieve a "perfect octet", in which the atom in question has 8 valence electrons. It is much easier to lose one electron than it is to try and gain seven more, so Sodium is very prone to losing it's only valence electron. Chlorine has the opposite situation. It has seven valence electrons, just one valence electron short of a perfect octet. Since it is easier to gain one electron than it is to lose seven, it will often react with elements that have just one spare valence electron, such as Sodium.
