What does element of interest mean in chemistry?
It means the element which you need to detect.
What are scientist doing to listen for signs of life on other planets?
Scientist have been sending rovers and astronauts to the other planets to detect life on other planets. (I think I'm not 100% sure,sorry)
Mg emits radiation at 285nm could a spectroscope be used to detect this emission?
285nm is ultraviolet, and I think with a spectroscope you actually look with your eye to see the emission - you would not be able to see this wavelength. If you put some kind of a film that reacts to UV light in the spectroscope, you could then "see" it as a mark on the film.
Which element is used as poison and is found in the title of a murder mystery?
carbon is used in rat poison and is the title of a murder mystery
How does performing tests on elements help you identify the element?
If you use high-end equipment such as electron microscopes, you can detect the amount of electrons are in an atom and therefore identify that element. Examples; 1 electron - Hydrogen 8 electrons - Oxygen 111 electrons - Roentgenium
What does element of interest mean in chemistry?
It means the element which you need to detect.
What is positron emission tomography used to diagnose?
Positron Emission Tomography (PET) scans are used in hospital mainly to detect cancers, especially cancers that have metastasised or spread into surrounding tissue.
What element is used to detect bone disease?
phosphoros
What man made element is now injected to detect parathyroid dysfunction?
The isotope iodine-131.
What does the element cesium smell like?
Cesium doesn't have a smell you need special equipment to detect Cesium.

What types of activities do scientist use technology for?
to use the computer for research on a certain topic

How would forensic scientist detect codeine?
HPLC (high pressure liquid chromatography), hair samples and bodily fluids can be tested this way.
When a scientist designs a probe to detect life on a distant planet what kind of things should it measure?
things like contents of atmosphere, heat, etc.
What is a stool sample?
It is a faeces (poo) sample, which can be used by a biomedical scientist to determine the cause of diarrhoea for instance, or detect the presence of occult (hidden) blood.
What are two kinds of information that astronomers can collect from stars by using spectrographs?
All elements have their own discrete power spectra. To excite a hydrogen atom requires a different amount of energy than to excite a helium atom. The energy of a photon is proportional to its wavelength. So by looking at the wavelengths in the absorption or emission lines in the spectra and comparing them to known energy levels (empirical or quantum mechanic derived) of different elements, a great deal can be said about a stars outer layer.
