Which combination of an element and an ion will react? view available hint(s) which combination of an element and an ion will react? sn(s) and mn2+(aq) will react. fe(s) and ca2+(aq) will react. ni(s) and pt2+(aq) will react. h2(g) and na+(aq) will react.

h let me think

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

we need the questions , i may then you.

they are all solids.
