This was surprising because it proved that a strong positive charge in the gold atoms must be repelling the positive particles. Rutherford suggested that the atom must have a strong positive central mass. This was called the nucleus. Elements in the same family alkaline Earth Metals — silver, lustrous, reactive Elements in the same period have the same number of energy shells. Elements in the family of noble gases are gases, odourless, colourless and inert unreactive.

Maximum number of electrons — a 2, 8, 8 b The alkali metals are highly reactive. This is because they have 1 valence electron. In order to become stable they only have to lose 1 valence electron which happens easily making them highly reactive.

Halogens have 7 valence electrons. To become stable Halogens gain 1 electron. This happens easily making them highly reactive. Noble gases have 2 or 8 valence electrons.

Thinking The most reactive solid is C bubbled vigorously. The least reactive is B no change. I think these elements are Metals because they have metallic lustre. I think these elements belong in group 2, the Alkaline Earth Metals. Solid B did not react with water or acid. All alkali metals are reactive with water, therefore these elements cannot belong to Group 1, the Alkali Metal group. Alkaline Earth Metals are not as reactive as Alkali Metals. Reactivity increases as you move down a metallic family.

Solid B did not react at all and is the least reactive. It would be the highest in the family. Solid A would be next, and Solid C would be at the bottom because it reacted with water and acid making it the most reactive.
