List the numbers of protons, neutrons, and electrons in Chlorine-18. (3 points)

Mama L [17]

The electronic configuration of Chlorine is 1s2 2s2 2p6 3s2 3p5.

There are three energy levels in chlorine

First energy level is n=1 has 1s2 so total 2 electrons

Second energy level is n=2, 2s2 2p6 so total 2+6= 8 electrons

Third has 3s2 3p5 electrons just 7 total... p can contain 6 electrons but only 5 are present. So the third level has lesser number of electrons than that can be filled

<h2>Hello!</h2>

The answer is:

The new volume will be 1 L.

$V_{2}=1L$

To solve the problem, since we are given the volume and the first and the second pressure, to calculate the new volume, we need to assume that the temperature is constant.

To solve this problem, we need to use Boyle's Law. Boyle's Law establishes when the temperature is kept constant, the pressure and the volume will be proportional.

Boyle's Law equation is:

$P_{1}V_{1}=P_{2}V_{2}$
