Recall all the atomic models you described in task 1. Think about the results each model would predict for Rutherford’s gold foil experiment. Which atomic models does Rutherford’s experimental evidence support? Explain why these models are compatible with the experimental results. The models in task 1 were Dalton's, Thomson's, Rutherford's, and Bohr's.

Electrons are extremely important to what area of technology? a) anti-aging research b) household product development c) electronics d) drug discovery

Which of the following describes qualitative data? a) recording the temperature of a solid as it is warmed. b) noting the color of a solution as it is heated. c) measuring the volume of an object by water displacement. d) taking the mass of an object using a balance.

The allotropes of carbon include a variety of structures that include three-dimensional tetrahedral lattices, planes of hexagonal rings, cylindrical tubes of hexagonal rings, and spheres of five- and six-membered rings. similar shapes of network covalent atomic solids are possible with carbon nitride, boron, and pure silicon (e.g., silicene is a graphene-like allotrope of pure silicon). in contrast, silicates exist as either highly ordered or amorphous (more random) three-dimensional lattices. what could explain why there are there no naturally occurring sheets, stacked sheets, cylindrical tubes, or spheres of network covalent atomic solids composed of silicon and oxygen (sio2)? would pure silicate structures make good lubricants or good electrical conductors?
