Study the reaction.
2AgNO3 (aq)+Cu (s)→Cu(NO3)2 (aq)+2Ag (s)
If the oxidation number of copper changes from 0 to +2, is this a redox reaction?
-No; copper gained 2 electrons and was reduced.
-Yes; copper lost 2 electrons and was oxidized.
-Yes, the products have 2 fewer electrons than the reactants.
-No, the products have as many electrons as the reactants.

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
