If you happen to have the periodic table on hand, try to have a closer look at the element with atomic number 17 and Cl as the chemical symbol. The name for that element would be chlorine, one of the most popular chemical elements for its extensive use in our daily routine.
There are a pair of stable isotopes that are contained by the natural occurring chlorine, they are chlorine-35 and chlorine-37. For having those two stable isotopes, the molecular weight of chlorine would be 35.4527. This chemical element is known as a greenish yellow gas which can be found in the nature.
The freezing point for this element would be 151 Fahrenheit degree below zero or minus 101.5 Celsius degree. In order to heat chlorine up to a boiling condition, you need raise up the temperature up to -34 Celsius or -29 Fahrenheit.
Those degree only apply for chlorine at normal atmospheric pressure, otherwise, the different measurements will come up. Chlorine is included into the halogens which is the 17th group in the periodic table. This group also covers some other chemical elements beside chlorine such as astatine, bromine, fluorine and iodine.
Chlorine has a number of physical properties attached. One of the most essential and noticeable physical properties of chlorine would be having more weight than air. If you conduct an experiment on this chemical element like releasing it to the environment, this element tends to collect in the areas of low-lying.
Now that you have the information about the chlorine molecular weight, you might as well read the rest of this passage to find some other useful information about this chemical element. Since it is listed as a member of halogen group in the periodic table, chlorine seems to have a number of chemical properties which are similar to those from bromine, fluorine, iodine and astatine.
The listing method in halogen group is based on the atomic weight of the chemical elements in the group. This system has placed chlorine somewhere between fluorine and bromine. Another unique chemical property of chlorine is that this element has a strong tendency when it comes to attracting many electrons from some other atoms. That what makes chlorine as a powerful oxidizing agent. This excellent capacity comes from the seven electrons in the outermost shell of chlorine.
We have figured out that the seven electrons of chlorine are highly electronegative. If we try to see the connection between the electronegativity of an element with its atomic weight, we will find out that the higher atomic weight a chemical element has, the less electronegative it becomes. In other words, we can say that chlorine is more electronegative than bromine yet it is less electronegative than fluorine.
Many chemistry experts have clearly stated that elemental chlorine could be very corrosive and toxic to our health. Once an individual incidentally inhales chlorine from the air, it is most likely that the person will experience irritated respiratory tract. You can tell the presence of this chemical element by its choking and unpleasant smell. Despite that fact, chlorine could be very beneficial to our life should you find it in the from of chloride ion.
