Why do elements with positive oxidation number easily combined with those having a negative oxidation number?
Elements with positive oxidation number easily combined with those having a negative oxidation number because opposite oxidation number attracts each other.
How do you get the ideal reading of chlorine in the pool?
When chlorine enters the water, it is in a form that is an active sanitizer and an oxidizer called "free chlorine". It will react with any number of contaminants in the water. When it reacts with ammonia compounds in the water, which come from bathers' perspiration and urine, it becomes "combined chlorine". In this form, chlorine is a much slower sanitizer. This form also causes chlorine odor and eye irritation. When using the 5-way strip, the difference between the free chlorine reading (pad 1) and the total chlorine reading (pad 2) is the combined chlorine reading.
Is chlorine a homogeneous mixture or a heterogeneous mixture?
Neither... It's an element. Chlorine is number 17 on the periodic table, and a mixture is a combination of 2 or more elements or compounds. Example: NaCl is Sodium and Chlorine combined to make a compound. I'm sure there are tons of different mixtures that contain chlorine, though.
Why does this indicate that most chlorine atoms contain 18 neurrons?
Normal chlorine is Cl-35. 35 represents the combined number of protons and neutrons. If you subtract the atomic number of 17 from this, you get 18, which is your neutron count. You can do this for every element; just take the atomic mass number, round it to the nearest whole number, then subtract the atomic number to get the neutrons.
What is the name of the element that has atoms that contain 17 protons?
the name of the element that contains 17 protons is chlorine
What element is used. To disinfect swimming pools?
Chlorine is used to disinfect Swimming Pools.
Why Oxygen and chlorine are not ionic compounds?
Oxygen and chlorine are each elements, not compounds. They combined to form a number of covalent compounds because they are both nonmetals.
Why do elements with positive oxidation number easily combined with those having a negative oxidation number?
Elements with positive oxidation number easily combined with those having a negative oxidation number because opposite oxidation number attracts each other.
What atomic number kills bacteria?
Chlorine, atomic number 17 kills bacteria. This is why it is placed in drinking water and swimming pools.

When a chlorine atom gains an electron what is it charge?
when the chlorine atom gains an electron its charge becomes -1. this is because the total number of electrons for chlorine is now 18. protons and electrons have the same atomic number, but when a chlorine ion forms it has one extra electron compared to the number of protons therefore giving it a negative charge of 1.

Can Chlorine oxidation number ever be negative two?
No, that is not possible for Chlorine. Some elements have more than one oxidation number, such as Iron, Mercury, Copper, etc, but Chlorine only wants to gain one electron. If it had a -2 charge, it would not be stable, so that would never happen.

What kinds of ions do a sodium atom and a chlorine atom become when a valence electrons is transferred from one to the other?
sodium becomes positive ( as it loses a negative electron but still hs the same number of + protons) with a single + charge. chlorine becomes negative ( as it gains an extra negative electron but still hs the same number of + protons) with a single - charge. NaCl -------> Na+ Cl-
