Add the number of protons for the atom in the 4th period, group 8 to the atom in period 5, group 17 together, then write the symbol of the atom and the number of protons that the new atom has based on the sum of protons from adding the protons from the first two atoms.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
