Chlorine belongs to halogen family. chlorine exists as diatomic molecule in nature.
Period 5 of the periodic table includes the halogen element bromine (Br). It is a highly reactive nonmetal and exists as a diatomic molecule in its natural state.
Helium does not readily form compounds and typically exists in its elemental form, which is neutral with an oxidation state of 0.
Sulfur
Less than one ounce of astatine exists on Earth. It was discovered by D.R. Corson, K.R. MacKenzie and E. Segre in 1940.
Bromine is a liquid nonmetal halogen in the fourth period of the periodic table. It is the only halogen that exists in a liquid state at room temperature.
Zinc commonly exists in compounds in the +2 oxidation state only, and as a metal with an oxidation state of 0.0, 1 and 2 oxidation states
Yes
The oxidation state of cobalt in CoCO3 is +2. It forms a ionic compound where cobalt exists as Co^2+ ion.
Chlorine belongs to halogen family. chlorine exists as diatomic molecule in nature.
Period 5 of the periodic table includes the halogen element bromine (Br). It is a highly reactive nonmetal and exists as a diatomic molecule in its natural state.
The most common oxidation state of chlorine is -1, where it exists as chloride ions (Cl-).
Yes, hundreds. Hydrochloric acid (HCl) in an aqueous solution (which, I suppose, is the only way it exists) is a simple example consisting of a positive hydrogen ion (H+) and a negative chlorine ion (Cl-). Table salt (NaCl) is another example, as are all the halogen salts (halides).
Symmetry exists naturally. Look at an animal, a leaf, or a flower and you will see symmetry (one side looks like the mirror of the other).
Helium does not readily form compounds and typically exists in its elemental form, which is neutral with an oxidation state of 0.
The oxidation state of tin (Sn) in SnCl3 is +2. Each chlorine atom has an oxidation state of -1, so in order for the overall compound to be neutral, the oxidation state of tin must be +2.
This contains H- ion. Li shows +1 oxidation number.
