When an electron jumps from an energy level that is farther away from the nucleus to an energy level that is closer to the nucleus the electron gives off energy. When doing a flame test this energy is in the form of a color change. One can identify the change based off of the color.

∙ 14y agoThe metals are heated over a flame. The energy they absorb excites the electrons. Only energy with certain wavelengths (colors) are absorbed. These wavelengths equal to the energy difference between the energy levels or "shells" in the atoms. The result is observed colors. For sodium it is yellow, for potassium it is lilac and barium it is red to mention some.

∙ 9y agoMany metal ions produce characteristic colors when exposed to various parts of a flame - including a Bunsen flame.
Addition/Edit: When heat is applied to metals [or any element], the electrons moves from one energy level to another and/or reacts to the flame. This reaction will determine the characteristic of the element.

∙ 12y agoThe heat of the flame excites the metals ions, causing them to emit visible light. The characteristic emission spectra can be used to differentiate between some elements.

What color does sodium hydroxide burn in a flame test?
Bright yellow :: This is the sodium ions. Any sodium compound will give a flame test colour of yellow/
Is metallic bonding an attraction of positive and negative ions?
Metallic bonding is the attraction between positively charged metal ions and free (negatively charged) electrons.
What is a bond formed by the attraction between positively charged metal ions and the electrons around them?
Metallic Bond .
How can viewing flame through cobalt glass make it easier to analyze the ions being tested in a flame test?
no Yes it does; the blue cobalt glass filters out the yellow of the sodium to make the metal ion easier to see.
A charged insulator can be discharged by passing it just above a flame explain how?
A charged insulator can be discharged by passing it just above a flame because a flame has a cloud of ions above it. Even though the overall charge above the flame is neutral, a charged insulator will use up the ions that it needs and neutralize.
Is flame coloration a test for the metallic ion or for the nitrate ion?
flame coloration is a test for the Metallic ion because the metallic ions will enter an exited state and release photons energy, in the form of light, as they return to their ground state.
What is the flame test for aluminum?
Aluminium ions like Magnesium ions have no colour in a flame test
How do you test for potassium ions?
Flame test
What difficulties may be encountered in the use of the flame test for identification of metallic ion?
A difficulty that may be found in using the flame test is eye imperfection. Another is subjectivity when it comes to perceiving the colors.
What was the flame test original use?
The flame test is used for the qualitative determination of some ions in solution.
How do you test for sodium ions and potassium ions when both are present?
Get a wire. Bend it into a ring and put a few crystals of your solid on it. Do a flame test using a Bunsen burner. Potassium will give a violet flame and Sodium ions will give a Yellow flame.
Does Copper Chloride produce a blue-green or Red flame?
In a flame test the copper ions in copper chloride will produce a 'blue/green' flame. To test for metal ions, the flame colour in a flame test is indicative of the metal present. Lithium = Red Sodium = Yellow Potassium = Lilac (pale purple). There are many more flame test colours.
What color does copper nitrate burn in a flame test?
The colour of any sample containing copper ions burns with a bluish green flame in the flame test.
How does a flame test indicate that ionic substances contain metal ions?
It is primarily used to indicate the presence of metallic ions since metals readily tend to lose electrons and therefore have electrons in the valence orbitals which can transition from one energy level to another.
What color does sodium hydroxide burn in a flame test?
Bright yellow :: This is the sodium ions. Any sodium compound will give a flame test colour of yellow/
What ions gives a bright orange flame test?
its either Na or Ca
Why is it difficult to identify potassium ions and sodium ions in low sodium salt using a flame test?
When sodium is subjected to a flame test, it burns a bright yellow. This yellow flame can be brighter than the lilac flame color of the potassium, which makes it more difficult to distinguish between the sodium and potassium.
