What has the least attraction for electrons?

Electrons closer to the center are held more tightly as proton number increases. However, outermost electrons are held less tightly because inner electrons shield them. For this reason, it is astatine that has the least attraction for its outer electrons. It also has the least tendency to gain more.... view details ›
