Model B: In this model the atom is a solid sphere that cannot be divided up into smaller particles or pieces. The atom is neutral and has no charge. Atoms of the same element are
mad of the same types of atoms.

Model D: In this model the atom is a sphere containing negatively charges particles
embedded in it. These small negative particles were originally called “corpuscles”
and later called electrons. However it was recognized that the atom is neutral (no
charge) so there must be an equal positive charge in the atom to offset the negative
charge of the electrons. Since no other particles were known at this time the rest of
the atom consisted of a positive charge.

It is possible to remove a negatively charged particle from an atom using electrical forces
(Thompson, 1897). Compare models B and D. Which model supports this evidence?

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next

Juju.01) 5 geologic events a group of students designed an experiment in an ice rink to represent the solar system. the steps of the experiment are listed below. 5: geologic events 1. choose a student to represent the sun. the planets are represented by two tennis balls. 2. ask the student to hold the tennis balls in each palm and spin on the ice with arms stretched out. 3. ask the student to draw in the arms after about 10 spins. 4. observe the student's arms rotate faster when they are closer to the body. 05 geologic events enors) the experiment most likely demonstrates that (2 points) 07 discussion-based sessment/module planets exert gravitational force on the sun the sun exerts gravitational force on the planets 3.07 discussion-based ssessment speed of a planet depends on its distance from the sun new version available!
