What is the process by which elements change to other elements by emission of ionizing particles?
Ionization
Why line spectrum is called finger print spectrum?
It is unique to a specific atom. The emission spectrum of sodium, for example, has two characteristic lines close together in the yellow part of the spectrum, which cannot be found in any other atom. Each line in a spectrum relates to a change in electron state or level.
What is the constituent elements of salt?
Table salt is NaCl, sodium chloride, composed of the elements sodium and chlorine. There are also many other types of salts, all composed of various combinations of metals and nonmetals.
What does sodium and chlorine have in common with each other?
Both are reactive chemical elements.
What elements make up hydrogen fluoride?
Fluoride is an ion consisting of a single atom of fluorine atom with a -1 charge. The fluoride in toothpaste and other dental products is sodium fluoride , consisting of sodium, and fluorine.
Can you describe an astronomical spectrum?
'Astronomical spectrum' is not a specific term. I suspect you are thinking of the emission spectrum of a star, which can tell us a great deal about the composition of the star. Light and other radiations from the object are spread out into constituent wavelengths and dark lines appear across the spectrum at certain specific wavelengths which are characteristic of elements present.
What is the process by which elements change to other elements by emission of ionizing particles?
Ionization
What elements are in sodium chloride other than sodium and chloride?
Sodium and chlorine are the only elements in sodium chloride.
What are Frequencies of light emitted by an element called?
"Spectrogram" is a word used to describe the set of specific characteristic frequencies of light which are emitted by a given chemical element when it is sufficiently excited by heat or by some other means.Alternatively, a scientific technique known as "spectroscopy" can be used to identify the elements in some matter of unknown composition and also the emission spectra of molecules can be used in chemical analysis of substances.Because each element's emission spectrum is unique, the "emission spectrum" of a chemical element or chemical compound can be used to help identify what it is. The "emission spectrum" is the name given to the relative intensity of each frequency of electromagnetic radiation http://www.answers.com/topic/emission-spectrum by the element's atoms or a compound's molecules when they are returned to a ground state.
What is the process in which elements change to other elements by emission of ionizing particles?
Radioactive decay.
Does sodium like to combine with other elements?
sodium combines with a lot of different elements.
Why line spectrum is called finger print spectrum?
It is unique to a specific atom. The emission spectrum of sodium, for example, has two characteristic lines close together in the yellow part of the spectrum, which cannot be found in any other atom. Each line in a spectrum relates to a change in electron state or level.
How can emission spectra used to identify presence of specific elements in a substance?
In atomic spectroscopy, each element has a unique spectrum. The atomic spectrum obtained from a sample is a combination of the spectra of each elemental component. We take the strongest line from the sample spectrum and determine which elements could have caused it (we call these "candidates"). We then look at the full spectrum from each candidate and see whether or not every major line is present in the sample spectrum. If so, we say that element is present.Then we subtract the spectrum (or spectra) of the element(s) we have determined to be present from the sample spectrum and repeat the same process with the next strongest line in the (leftover) sample spectrum. We continue repeating this process until all lines in the sample spectrum are accounted for.
What are other characteristic properties that may be helpful to identify elements or types of matter list at least two and briefly describe them?
Examples:- chemical composition- emission spectrum- X-rays lines- melting point- color- densityand many other
What would be observed if the flame tests were viewed through a spectroscope?
Emission spectrum of the elements placed in the flame. The flame test is usually applied when Sodium, Potassium or other such metals are thought to be present since they give a very noticeable result - Sodium gives orange colour to the flame (as it does to sodium street lighting!) - Potassium gives a lilac colour etc
Can sodium combine with other elements?
Yes, it can, and it combines with many other elements. The most common example is sodium chloride, ordinary table salt.
Which element couse difficulties in flame tests of other elements?
sodium
