Answer:
Explanation:Hurricane are fast moving that blows. It is formed over warm waterbodies and it can destroy lives and properties.
Florida is a state in united state while New york is an extention from florida. Florida is know to be contain many water bodies and the rise of warm water over time could lead to hurricane. Hurricane in New york will be few because its just a city in florida there are still many mkre cities in florida such that when hurricane occurs it of great impact.
Answer:
Potassium
Explanation:
From the given riddle. Potassium is the right answer. This because on the periodic table, potassium has the smallest atomic number of any element in its period with the electronic configuration 1s2 2s2 2p6 3s2 3p6 4s1, it has the largest atomic radius within its group because the radius has no d-electron shell filled. Potassium is a soft metal but contains high reactivity.
Aluminum has an atomic number of 13. The electronic configuration of Al is 1s2 2s2 2p6 3s2 3p1. Al3+ has only 10 electrons so the configuration of Al 3+ is 1s2<span> 2s</span>2<span> 2p</span><span>6. The highest energy level is 2 so the number of electrons in the highest level is the valence electrons which is 8.</span>
