Answer #1

Electrons exist around the nucleus of an atom in discrete, specific orbits. Electrons can not just exist at any distance from the nucleus. These orbits are called levels and we number them 1, 2, 3, 4, and so forth with the 1st level being the orbit closest to the nucleus.

The levels can be broken down into sublevels. We have s, p, d, and f .

sublevels refer to energies associated with electrons. Electrons present in same shell but different subshells have different energies.

Scientists want to find out if higher levels of hydration lead to higher energy levels. They asked a group of 105 volunteers to track their daily water intake along with their daily energy level (low, medium, or high) for 60 days. If the volunteers who drank more water also report significantly higher energy levels than the volunteers who drank less water, can the researchers conclude that drinking more water causes an increase in energy levels? Explain.
