2. Imagine there is a piece of lead (Pb) that has 1,000,000 atoms in it and a piece of cobalt (Co) with 1,000,000 atoms in it. Interpret the properties of the two atoms and make a scientifically supported judgement on
which piece has a greater mass. (max 7/8)

In which phase(s) do the molecules take the shape of the container?

In an investigation that uses the scientific method, which step immediately follows making a hypothesis? o summarizing the results o asking a question o making observations designing an experiment mark this and retum save and exit next submit

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.
