Ksivusya [100]

Answer:

5.733 days

Explanation:

To convert from minuets to days we must first convert minuets to hours. To do this we divide by 60 since there are 60 minuets in one hour.

8255 min ÷ 60 = 137.6 hr

Now that we have the amount of hours we can convert to days by dividing by 24 since there are 24 hours in one day.

137.6 hr ÷ 24 = 5.733 days

Marrrta [24]

Answer:

Orbitals

Shells

Energy Levels

Explanation:

Elements in the same period will have the same energy levels which is the same as orbitals and shells.

  • The period of an element indicates the energy level in an atom.
  • Elements in period 1 will have one energy level or shell or orbitals.
  • Down a group this is not the case.
  • The energy level increases from top to bottom.
  • As we go down the group, we are transiting from one period to another.
