Explain the relationship between an element’s position on the periodic table and its Bohr model and electron configuration. Focus on the period (row) and group (column) and element are in and what that tells us about that element’s Bohr model and electron configuration. Provide an example in your response.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
