It depends what is meant by 'decay'. It will not alter the atomic decay rate but elements can be chemically affected by the environment which can chemically decay them.
the atoms are held together because they a chemically combined.
Held responsible
You probably meant 1948, not 1048. The 1948 Olympics were held in London, UK.
Ionic bonds are very weak, and ionic compounds are very weakly held together chemically.
"Growth of slave power" refers to the increase in political influence and economic power wielded by slaveholders in the United States prior to the Civil War. This power was manifested through laws and policies that supported the expansion of slavery into new territories and the protection of slaveholder interests.
the political influence held by slaveholdeers in the south.
Chemically orthogonal means that two functional groups or molecules do not engage in similar/identical chemical reactions or exhibit significant differences in their chemical reactivities. An amino and a nitro are chemically orthogonal nitrogen-functions. On the other hand, an aldehyde and a ketone can be considered chemically very similar with respect to most reaction conditions. I have to admit that this terminology is rather general and does apply to many functions. It is probably not of too much use.
The event is held to celebrate the Easter holiday
He held a symbol called the Ankh which meant "Eternal Life"
The complex carbohydrates (cellulose, starch, and glycogen) are polysaccharides composed of chemically bonded glucose molecules.
Chemical bonds are what hold together the atoms of a compound. The chemical bonds are formed as a result of the interaction of the electrons from each atom.
