How do you write electron affinity in equation? F(g) + e- ——> F-(g) -328 kj/mol

Or

F(g) + e- ——> F-(g) +328 kj/mol

I know that energy is released when the atom wants e-, but don’t know if I should use + or - .

Thanks in advance.

Which of these is a physical property

Vi limitens. vastery test select the correct answer. which statement explains why large atoms are more reactive than small atoms? a. large atoms have valence electrons farther from the nucleus and lose them more readily. b. large atoms have greater ionization energy, which they can utilize during a reaction. c. large atoms have a greater number of electrons that they can lose during a reaction. d. large atoms have more energy levels, so they have more energy to pass on in a reaction. reset next
