What part of the flame identifies the elements in the compound?
the bottom part
Why did each compound produce a flame of a different color?
Different elements have different emission spectra, meaning that if the electrons in an atom are excited, they will release that energy in different color of light. The flame color depends on the elements in the compound.
What information does a flame test provide?
The emission spectrum of an element
What can a flame test tell you about a certain compound?
No, because non metal atoms do not enter an excited state.
What two of this elements compound burn with a red flame and are used in fireworks and signal flares?
Lithium, strontium and calcium have red flames.
Conclusion in flame test?
In a flame test, the color of the flame produced can be used to identify the presence of certain elements in a compound. This is due to the unique way each element emits light when heated. By observing and comparing the color of the flame with known standards, one can draw conclusions about the elements present in the sample being tested.
What was the flame test original use?
The flame test was originally used as a qualitative analysis technique in chemistry to identify the presence of certain metal ions in a compound based on the color emitted by the flame when the compound is burned. This method is still used today in chemical analysis and identification of elements.
A flame test can be used to identify the presence of certain elements in a compound?
Not in the "natural" elements (the first 92), but we know of no limit to the trans-urantic elements. A2: Some gases were first discovered by their spectrums--the yellow line of helium in the sun was observed long before it was found on earth.
Which combination describes the flame color of the compound when heated?
Which combination describes the flame color of the compound when heated?
What identifies elements?
atomic number
Do only s-block elements give flame test?
No, many elements outside the s-block will also give a flame test.Here are a few examples.Some d-block elements include:Copper (blue-green flame)Manganese (yellowish green flame)Zinc (blue-green flame)Some p-block elements include:Lead (blue flame)Thallium (green flame)Selenium (azure flame)
Why can you not use flame tests to identify all the elements?
1. not all elements give colour to the flame 2. flame test is not always accurate
