What is the maximum number of electrons that can be held in the first electron energy level of an atom? In the second energy level?

Sagot :

Answer:

first electron level-2 electrons

Explanation:

Answer:

1st energy level - 2 electrons

2nd energy level - 8 electrons

Explanation:

Maximum number of electrons that a main energy level can occupy depends on type and number of sub energy levels.

s orbital can occupy 2 electrons. p orbital can occupy maximum 6 electrons.

1st energy level has only a single s orbital, thus can have upto 2 electrons.

2nd energy level has a s orbital and a p orbital. 2 +6 = 8 electrons
