The elements that natural occur in a bond is convered by the HOBrFINCl rule, with some exceptions. These non-metals naturally exist in compounds: H2 O2 Br2 F2 I2 N2 Cl2 as well as O3 P4 S8 there is no metals that exist in pairs or in compounds naturally without a chemical reaction.
group 2 (the alkaline earth metals) are: * They occur in nature only in compounds because of their high reactivity. They are less reactive than group 1 elements due to higher IE.
Group 1 elements because they are highly reactive
Examples: sodium, potassium, aluminium, uranium and many others.
Reactive chemical elements exist as compounds.
Sodium
Potassium
group 2
an element is chemically active till it does not attain an inert gas configuration.
Some chemically active elements include oxygen, chlorine, fluorine, lithium, sodium, potassium, and iodine. These elements readily participate in chemical reactions to form compounds with other elements.
Meitnerium is a radio-active ELEMENT. There are No compounds in Meitnerium. However, it is thought that it may form the fluorides MtF6 and oxide MtO4
Nickel is one of the less chemically active metals. It does not easily combine with other elements.
Alkaline metals are usually found only as compounds in Nature because these metals are very active chemically and will combine with many commonly found substances such as water.
an element is chemically active till it does not attain an inert gas configuration.
noble gas
An element is chemically active till it does not attain an inert gas configuration.
Hydrogen...
i am pretty sure that when an atom is chemically active its outer valence shell is not full meaning it is able to form different types of bonds with different elements.
Fluorine
Francium is a very radioactive and very chemically reactive chemical element.
false
Fluorine is sometimes called the hungry wolf of the periodic table because it is the most reactive element.
Plutonium is not an inert chemical element, plutonium is very active.
The nobel gases for the most part. He, Ne, etc
Carbon, if not wiki it
