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)

What do flame test show about the structure of atoms?
Flame tests show that different elements emit unique colors of light when heated, indicating that each element has its own signature set of energy levels for electrons. This is due to electrons moving to higher energy levels when heated and then falling back down, releasing energy in the form of light.
What are the limitations to a flame test?
· The test cannot detect low concentrations of most ions. · The brightness of the signal varies from one sample to another. For example, the yellow emission from sodium is much brighter than the red emission from the same amount of lithium. · Impurities or contaminants affect the test results. Sodium, in particular, is present in most compounds and will color the flame. Sometimes a blue glass is used to filter out the yellow of sodium. · The test cannot differentiate between all elements. Several metals produce the same flame color. Some compounds do not change the color of the flame at all. The flame test only works on certain molecules, more specifically the Alkali/Alkali Earth metals. It doesn't necessarily distinguish between compounds of these molecules neither.
What is the purpose of using the cobalt glass in the identification of potassium and sodium?
Cobalt glass filters out yellow light, allowing only violet and blue light to pass through. Sodium produces a bright yellow flame color that is masked by cobalt glass, while potassium produces a light purple flame color that is visible through the cobalt glass. This technique helps distinguish between the two elements based on the flame color observed.
What kind of flame do you get from a good Bunsen burner?
Im Only 14 But I Hope This Helps A Good Bunsen Burner is used in laboratories to heat things. A Bunsen burner can produce 3 different types of flames: The "coolest" flame is a yellow / orange color. It is approximately 300°C. It is never used to heat anything, only to show that the Bunsen burner is on. It is called the safety flame, The medium flame, also called the blue flame or the invisible flame is difficult to see in a well-lit room. It is the most commonly used flame. It is approximately 500°C, The hottest flame is called the roaring blue flame. It is characterized by a light blue triangle in the middle and it is the only flame of the 3 which makes a noise. It is approximately 700°C. The Flame Changes Colour Depending On The Air Hole Thingy On The Bunsen Burner.
Is blue flame usable?
Yes, blue flame is usable. It is hotter than a yellow flame and can be used for tasks that require high heat, such as welding, brazing, and glass blowing. Blue flame is often preferred for its efficiency and cleanliness in combustion processes.
When is the flame extinguished?
This occurs only when the flame is robbed of oxygen.
Is the flame test a qualitative or quantitative test for the identity of an unknown?
just looking at the color of the flame --- qualitative
What do flame test show about the structure of atoms?

This is due to electrons moving to higher energy levels when heated and then falling back down, releasing energy in the form of light.
Why do sodium chloride and sodium nitrate impact the same color of the flame?
The yellow color of the flame is due only to sodium.
How do you increase the temperature of a yellow flame coming out of a busen burner?
You can't it is always the same. You only use the blue flame to heat things because the yellow flame is the safety flame and the blue flame is hotter.
Is a flame test a qualitative or quantitative test?
The flame test in analytical chemistry is only qualitative.
How many liquids are there on the perodic table?
The state of elements depends on the temperature. Most periodic tables give the state of the elements at room temperature. Since only mercury and bromine are liquids at room temperature, these are the only elements listed as liquids on the periodic table.
How does lithium serve as an ionization suppressant in flame photometry?
Berry, Chappell & Barnes (1946) showed that, in estimating sodium and potassium by flame photometry, there were definite improvements in precision and accuracy when lithium was added to the samples as an internal standard (compare Spencer, 1950; Bernstein, 1952). The lithium internal standard signal reduces fluctuation in flame conditions, drift, and dilution errors—ensures reproducible results and precise measurements. The fully automatic ignition and flame optimization sequences reduce set up and calibration time. An automatic gas shutoff mechanism activates if the flame is accidentally extinguished. The monitoring and control software make operation simple and allow measurements only after blanking and calibration.
Why does the anion not play a role in the color of a flame in a flame test?
Anions do not play a role in the color of a flame in a flame test because they are not visible as the energy gap do not correspond to that of a visible photon. Flame tests are only applicable to cations.
Why is a flame a good symbol for natural gas?
Because the flame is the only symbol they could think of XD
How do you get flame wingman?
you can get it in jaden yukis,wich not only contians flame wingman,but also elemental hero avian and burstinatrix,which is flame wingmans fusion material
Is it sufficient to identify a cation on a flame test?
It is not suffiecient to identify a cation only on a flame test.æ You must also identify the color of the flame which corresponds to a certain element.
