Well, first off it tells you the number of valence electrons (because that’s what those are valence electrons) it also tells you how that atom is going to bond with other atoms (whether it will tend to loose or gain electrons when in chemical bonds). It also can show how reactive an element is (if it has eight or in some cases two then it won’t react because that outer shell is full)...basically it tells you the chemical properties of that atom
Answer:
Barrier island
Explanation:
Barrier islands represent a class of coastal landform composed of sand and sediments that forms parallel to the coast. These islands are constantly changing, being shaped by different factors which include water currents (ocean currents), erosion and waves. Some of the most important parameters that influence the length and width of barriers are tidal range (i.e., the height difference between high tide and low tide), wave energy (i.e., the energy restrained from oceanic waves), the amount of sediment supply and sea-level trends.
Plasmid. These are circular DNA segments found in bacteria and can help them exchange DNA with each other.
