n the Bohr model of an atom (shown), protons are represented in blue, the neutrons are red and the electrons are green. Use your periodic table and determine which of the following atoms is represented by the Bohr model.

B

Explanation: Valence electrons are the number of electrons out the outermost shell of the diagram. In this diagram, there is one valence electron. This means that it is highly reactive since the shell is not complete and needs other elements to be able to complete the outermost shell. If this model had a full outermost shell, then it would not be reactive (noble gases).

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
