Explanation:
Any orbital can hold a maximum of 2 electrons with opposite spin. The first shell has one 1s orbital and holds 2 electrons. The second shell holds 8 electrons; 2 in a 2s orbital and 6 in three 2p orbitals. The third shell holds 18 electrons; 2 in a 3s orbital; 6 in three 3p orbitals; and 10 in five 3d orbitals.
An eclipse is when two celestial bodies lines up in space and one of the objects gets partially or totally blocked. This could happen when the sun blocks the moon, or when the moon blocks the sun. These are just some of the examples there are many others out there, so the answer would be Eclipse!
Hope this helps and stay safe!
