Consider the position of barium, sulfur, silicone, and calcium on the periodic table the atoms of which element requires the least amount of energy to give up an electron when forming chemical bonds?

Describe the redox reaction. Check all that apply 2AI (s) + 3ZnCI2 (g) → 3Zn (s) + 2AICI3 (aq). Aluminum atoms transfer electrons to chlorine atoms. Zinc is reduced. Zinc is the reducing agent. The oxidation number of chlorine does not change.

What trend does the first ionization energy follow, going down the periodic table? A. The first ionization energy increases because there are more electrons in the atom. O B.
