Chemistry Questions

Radioactive decay is likely to occur when the nuclei of an atom doesn't have enough binding energy to hold the nucleus together due to excess of rotons or nutrons in it.

Shock resisting steels should have toughness.

S-5 is a silico-manganese shock resisting steel that offers good ductility.

Law of Octaves states that "If the chemical elements are arranged according to increasing atomic weight, those with similar physical and chemical properties occur after each interval of seven elements." That is every 8th element have the same physical and chemical properties. This was established by the British scientist John Newlands in the year 1865.

In thermodynamics, deposition is a phase transition in which gases are directly transformed to solids without converting to liquids first.

For example, watervapour is directly changed to ice without first becoming to liquid water. In this process, heat is released making the process exothermic process.
