Answer Wiki. Sand sharks a/k/a sand tiger, grey nurse and ragged tooth. Their name reportedly comes from their habit of hanging out near the shoreline, trolling the ocean floor where the waves break close to the beach. While they're considered relatively docile and mind their own business, they apparently will attack a human if provoked.
Contemporary energy transitions differ in terms of motivation and objectives, drivers and governance. In a more narrow sense, a sustainable energy transition is the shift by some countries, most notably Germany (German: Energiewende), to decentralised renewable energy, and energy efficiency.
The second ionization energy is always larger than the first ionization energy, because it requires even more energy to remove an electron from a cation than it is from a neutral atom.The first ionization energy varies in a predictable way across the periodic table.The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest. similar effect occurs in aluminum, which has an electron configuration of 1s2 2s2 2p6 3s2 3p1. Even though oxygen is to the right of nitrogen in period 2, its first ionization energy is slightly lower than that of nitrogen.
