Question

Look up chlorine in the Periodic Table (Cl). Then, answer the following questions:

The number of electrons in n = 1 level?
The number of electrons in n = 2 level?
The number of electrons in n = 3 level?
Choose the letter with the 3 correct answers.
2,8,7
7,8,2
2,6,9
8,2,7

Answer 1

2, 8, 7
Cl has 17 electrons distributed on 3 levels
level 1 has 2 electrons, level 2 has 8 electrons, level 3 has 7 electrons

Answer 2

2,8,7

Step-by-step explanation:

Chlorine contains a total of 17 electrons distributed between three shells. From Bohr's theory, each shell represents an energy level (n). Hence it is safe to say that there are three energy levels in chlorine; n=1, n=2 and n=3. Each of these levels possesses a minimum of two electrons and are arranged in the order:

n=1, two electrons

n=2, eight electrons

n=3, seven electrons.

Hence the answer.
