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
Answer:
LiCl - pink
NaCl - yellow
KCl - purple/blue-violet
CaCl₂ - orange/orange-red
Hope this helps.
Answer:
4 atoms of Chlorine
Explanation:
This is actually easy to explain,
First we have here a type of nomenclature. This one is the sistematic nomenclature, and begins by naming the number of atoms that one element has, beggining for the non metal first, and then the metal or the non metal acting like a metal. In this case, the Carbon is acting like a metal.
The number of atoms are named by a prefix of the number. Each number has a determined prefix. Here are some of them:
one = 1 = mono
two = 2 = bi or di
three = 3 = tri
Four = 4 = tetra
Five = 5 = penta
Six = 6 = Hexa
So tetrachloride, means that we have 4 atoms of chlorine in the molecule and the molecule is this one: CCl4
Answer:
15000N/m²
Explanation:
Given parameters:
Force exerted by the girl = 450N
Area = 300cm²
Unknown:
Pressure exerted by her feet =?
Solution:
Pressure is the force per unit area on a body;
Pressure = 
We need to convert the given area to m²;
10000cm² = 1m²
300cm² = 
= 0.03m²
Pressure = 
= 15000N/m²
