Answer 2

Formula for F, CL, AL and their Valency and Oxidation State

The formula for the elements F (Fluorine), Cl (Chlorine), and Al (Aluminum) are as follows:

- Fluorine (F): The chemical symbol for fluorine is F. It is a highly reactive nonmetal and is the lightest halogen. The valency of fluorine is 1-, meaning it tends to gain one electron to achieve a stable electron configuration. The oxidation state of fluorine is -1.

- Chlorine (Cl): The chemical symbol for chlorine is Cl. It is a highly reactive nonmetal and is a member of the halogen group. The valency of chlorine is 1-, meaning it tends to gain one electron to achieve a stable electron configuration. The oxidation state of chlorine can vary depending on the compound it is in. For example, in compounds like HCl, the oxidation state of chlorine is -1, while in compounds like Cl2O7, the oxidation state of chlorine is +7.

- Aluminum (Al): The chemical symbol for aluminum is Al. It is a lightweight metal and is the most abundant metal in the Earth's crust. The valency of aluminum is 3+, meaning it tends to lose three electrons to achieve a stable electron configuration. The oxidation state of aluminum is +3.
