hope it clarifies ur doubt dear friend..
because it has s the less electron in the outer most shell
Period 1 is the answer...
As Oxygen has lesser no of shells as compared to Sulphur and its e are more tightly held hence they accept e more easily than Sulphur.
cl is having less electron affinty than F
combustion of methane in oxygen to form carbon dioxide and water.
2 lead nitrate reacts with potassium iodide to form lead iodide and potassium nitrate.
3 aluminum chloride reacts with barium hydroxide to form barium chloride and aluminum hydroxide.
answer these 3 questions...
The electron affinities of the noble gases have not been conclusively measured, so they may or may not have slightly negative values. Chlorine has the highest Eea while mercury has the lowest. Eea generally increases across a period (row) in the periodic table, due to the filling of the valence shell of the atom.
Fluorine, which is higher up the group then chlorine, has a lower electron affinity. This is because the electrons in the outermost shell of a fluorine atom are closer together. ... Energy is required to keep the gained electron in the shell, causing fluorine to have a smaller electron affinity than chlorine.
Its option A
Li has lower E.C and have only 3 electrons
