What were the conclusions of rutherford's gold foil experiment ?

1. most of the space inside an atom is vacant.

2. there is a tiny dense nucleus on the centre of atom.

Explanation:

since most of the alpha particle ere unscattered on passing through the gold foil he said that most part of atom is vacant. also as some alpha particle got strongly deflected on passing through the center he also made conclusion that the nucleus is small and positively charged and at the center of atom.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

false

because it does not have the potential to be entirely used up
