They only get the black ring if you do not refresh after cooking, as soon as the eggs are boiled pour off the hot water and put the eggs under a cold running tap for a few minutes, this quickly cools the eggs and prevents the black ring.

proteins contains S (sulphur)
Silver is Ag
2Ag + S --> Ag2S
Ag2S is black coloured. chemical reaction to the protiens in the egg and the silver. Sulfur in the egg tarnishes the spoon. Because sulphurous compounds silver sulphide will be formed and silver spoon will have black spots of silver sulphide.

When copper reacts with silver nitrate what element is set free?
If the silver nitrate is in aqueous solution and the copper is solid in contact with the solution of silver nitrate, copper atoms will dissolve as ions from the surface of the copper and be replaced by silver atoms formed from the silver ions in solution. This reaction will continue until the entire surface of the copper in contact with the solution is covered with silver. The chemical driving force for this reaction is displacement of one element from its compounds by another element that is higher in the electromotive series than the element displaced.
