How do you know if the element is positive or negative?
To find the ionic charge of an element you’ll need to consult your Periodic Table. On the Periodic Table metals (found on the left of the table) will be positive. Non-metals (found on the right) will be negative.

What is the 2 in CL2?
Cl2 is a diatomic molecule, whereas 2Cl means 2 units of a negatively charged chlorine anion in a chemical equation. These ions are NOT bonded to each other. The 2 written in Cl2 means that there are two chlorine atoms covalently bonded to form a chlorine molecule.

Is chlorine OK for kids?
Pool chlorine does more harm than good to our children by causing skin irritation, an increased risk of bronchiolitis, and a heightened chance of having allergic sensitization and asthma throughout their lives. Take preventative action with a non toxic, chlorine alternative pool treatment system.

What makes chlorine unique?
Chlorine is a toxic gas that irritates the skin, the eyes and the respiratory system. Characteristics: Chlorine is a greenish-yellow, diatomic, dense gas with a sharp smell (the smell of bleach). It is not found free in nature as it combines readily with nearly all other elements.
What are benefits of chlorine?
Besides killing dangerous germs like bacteria, viruses and parasites, chlorine helps reduce disagreeable tastes and odors in water. Chlorine also helps eliminate slime bacteria, molds and algae that commonly grow in water supply reservoirs, on the walls of water mains and in storage tanks.
What is a dangerous level of chlorine?
6 ppm
Is chlorine found in a pure form?
Chlorine is very reactive and, as a result, is not found in its free form in nature, but only in compounds with other elements. It will dissolve in water, but will also react with water as it dissolves. Most common chlorine compounds are called chlorides, but it also forms compounds with oxygen called chlorine oxides.
