Scientists can make atoms of large elements which have not been previously known. Identify an element that would have similar pr
olasank [31]

Answer:

Radon

Explanation:

One element that will have similar property as an atom with 118 protons is Radon because it will belong to the p-block and the noble gas group.

The element will follow atomic number 117 which is already in the 7th group on the periodic table.

  • Generally, on the periodic table, elements in the same group will have the same chemical property.
  • The valency of most elements determines their chemical behavior.
  • Since our mystery element is in the 8th group, noble gas group, it will mostly behave like any of the elements in the group.

Describe how species on the Galapagos islands have changed over time
GarryVolchara [31]
Five to ten million years ago, the tops of underwater Galapagos volcanoes appeared above water for the first time about 600 km from mainland Ecuador in the middle of the Pacific Ocean. Those volcanic peaks were completely devoid of plant and animal life. All plants and animals that are now native to the islands must have arrived to the islands originally through some form of long-distance dispersal.There are two main ways for species to make their way to remote islands. The first method is by air in the form of flying or being blown by wind, and the second method is by sea while swimming or floating, sometimes with the aid of rafts of tangled vegetation.
