Ground state

Answer 22

lowest possible energy state of an electron

Question 23

Daltons atomic theory

Answer 23

Atoms cannot be broken down into smaller pieces, atoms of the same element are identical (Both wrong)

atoms of different elements are different, chemical reactions are a rearrangement of atoms (true)

Question 24

Plum Pudding model

Answer 24

positive and negative charges are embedded in the nucleus (wrong)

Rutherfords Gold Foil Experiment

Answer 26

1. Atoms are composed of mostly empty space
2. The nucleus is a dense mass with a positive charge

Question 27

Bohr

Answer 27

Electrons go around the nucleus in orbits (Wrong)
