They are Halogens
Group 7A elements have 7 electrons in their valence level, while Group 7B elements have 17 electrons in their valence level. This difference occurs because elements in Group 7A have 7 valence electrons, while elements in Group 7B have 7 valence electrons plus the 10 additional electrons in the d sublevel which contributes to a total of 17 valence electrons.
Sodium and Chlorine = Sodium Chloride Potassium and Iodine = Potassium Iodide
The usual charge on an ion from group 7A (also known as group 17) is -1. This is because elements in group 7A, such as fluorine, chlorine, and bromine, typically gain one electron to achieve a full outer electron shell, resulting in a -1 charge.
Valence electron configuration in group 7A (halogens): ns2, np5 in which n=2, 3, 4, 5, ... etc. Starting with fluorine, F, electron configuration: (1s2), 2s2 2p5 (non valence electrons in () brackets)
The Group 7A elements, also known as the halogens, typically form ions with a charge of -1. This is because they only need to gain one electron to achieve a stable electron configuration similar to the nearest noble gas.

No, Group 7A elements are the halogens - a highly reactive group of nonmetals. Alkaline earth metals are found in Group 2A of the periodic table and are characterized by being shiny, silvery-white metals that react readily with water.

Group 7A cations refer to the cations of Group 7A elements in the periodic table, also known as the halogens. Some common examples of Group 7A cations include fluoride (F-), chloride (Cl-), bromide (Br-), and iodide (I-).
The elements in group 7A or 17, gain one electron during ionic bonding, or share one electron when undergoing covalent bonding.
The highly reactive elements in group 7A, also known as group 17 or the halogens, are fluorine, chlorine, bromine, iodine, and astatine. These elements are known for forming salts by gaining an electron to achieve a full outer electron shell.
If you meant to say "elements ARE most likely to bond with," which is probably what you meant, then the answer would be 7A(or 17), also called the Halogens. "Halogen" actually means "salt-forming." When you take a chlorine (7A) and sodium (1A), you end up with table salt! ---- In a nutshell, the answer is Group 7A, or 17.
Halogens are placed in Group 7A of the periodic table because they have seven electrons in their outermost energy level, making them highly reactive and likely to gain one electron to complete a full valence shell. This characteristic is consistent with other elements in the same group, which also tend to gain an electron to achieve stability.
Potassium is a metal, and it would react to group 17 (7A) because those elements are nonmetals.
