Because halogens have seven valance electrons they tend to accept one electron into their valance shell to complete the octet of eight valance electrons. Naturally, electrons are negatively charged giving the anion a - 1 charge.

Set c (Rb, Sn, S) tends to form anions in binary ionic compounds. Rb is a metal that tends to lose an electron to form a cation, while Sn and S are nonmetals that tend to gain electrons to form anions.
In general, metals form cations (positive ions) and non-metals form anions (negative ions.) This is because metals have fewer valence electrons, and lose them when they bond, and non-metals have more, and gain them when they bond.
Anions are negative ions, so any element that gains a negative charge in a chemical reaction. Some examples of elements that commonly do this are the halogens (flourine, chlorine, bromine, iodine, astatine) and oxygen.
Halides are typically anions, not cations. Anions tend to be electronegative because they have gained electrons to achieve a stable electron configuration. Cations, on the other hand, are positively charged and usually not considered electronegative.
Non metals tend to form Anions as they gain electron(s). This occurs normally and usually naturally. There are cases where nonmetals can become Cations as well but it would take a lot of energy to take away an electron from the valence shell. (Refer to Ionization Energy)
No. Metals generally have lower electronegativity and form cations.

In binary ionic compounds, elements that tend to form anions are typically nonmetals. From the given options, sulfur (S) and iodine (I) are nonmetals that commonly form anions (S²⁻ and I⁻, respectively) when they react with metals. Other elements listed, such as calcium (Ca), potassium (K), and iron (Fe), are metals that tend to form cations rather than anions.
Anions are negative ions, so any element that gains a negative charge in a chemical reaction. Some examples of elements that commonly do this are the halogens (flourine, chlorine, bromine, iodine, astatine) and oxygen.
Bromine (Br) tends to gain electrons. As a halogen, it has seven valence electrons and seeks to achieve a full octet by gaining one additional electron. This makes bromine more likely to form negative ions (anions) in chemical reactions.
Atoms that tend to form ionic bonds are typically metals that readily lose electrons to form positively charged ions (cations) and non-metals that readily gain electrons to form negatively charged ions (anions). This transfer of electrons creates an electrostatic attraction between the positively and negatively charged ions, resulting in the formation of an ionic bond.
Halides are typically anions, not cations. Anions tend to be electronegative because they have gained electrons to achieve a stable electron configuration. Cations, on the other hand, are positively charged and usually not considered electronegative.
elements which have 1 to 3 valence electrons will generally lose electrons and form cations. elements which need 1 to 3 electrons to attain the nearest noble gas configuration will generally gain electrons and form anions
Non metals tend to form Anions as they gain electron(s). This occurs normally and usually naturally. There are cases where nonmetals can become Cations as well but it would take a lot of energy to take away an electron from the valence shell. (Refer to Ionization Energy)
They become anions, with negative electrical charge.
No single element can be both an alkali metal (form +1 cations) and a halogen (form -1 anions).Alkali metals :LithiumSodiumPotassiumRubidiumCesiumFranciumHalogens:FluorineChlorineBromineIodineAstatine
