What is the finger print of an atom?
Further study of emission spectra revealed that each element produces a unique set of. spectral lines. For this reason, the line spectrum of a given element is sometimes referred to as an. “atomic fingerprint.
Why atomic number is called fingerprint?
The chemical and physical properties of an atom are solely determined by the number of its electrons and hence by its nuclear charge: the nuclear charge is a unique “fingerprint” of an element and Z labels the chemical elements uniquely. …
Can you create elements?
You can not create new elements by mixing different compounds. In order to create a new element you have to change the number of protons in a nucleus. It is possible to do this but it requires bombarding various elements, one with the other, by means of high energy particle accelerators.
