Which one of the following metal burns with brick red flame when heated in air?
Lithium is the metal that burns with a brick red flame when heated in air. This characteristic flame color is due to the presence of lithium ions, which emit a specific wavelength of light when they are excited by heat. Other alkali metals may produce different flame colors, but lithium's distinctive brick red hue is unique to it.
What alkali metal produces violet flame when mixed with water?
Lithium is the alkali metal that produces a violet flame when mixed with water. This color arises due to the excitation of electrons in the lithium atoms, leading to the emission of light in the violet part of the spectrum.
Which group of s block elements show distinctive colors when they interact with fire?
this is because of s-p transition.when electron jumped from s to p it gain some energy.and when this electron came back to s -orbital ,,it releases this energy.it is this energy which gives colour in flame of s-orbital
What is the major difference between the colours of flames produced by alkali metal with that of calcium when performing flame tests?
The major difference is the color of the flame produced. Alkali metals typically produce a lilac or purple flame, while calcium produces an orange-red flame. This difference is due to the unique electronic configurations and energy levels of the atoms in each element.
What alkali metal reacts most slowly with water?
Lithium (Li) is the alkali metal that reacts most slowly with water. It is the first alkali metal and thus, the least reactive of the group. The lithium metal is seen to dart around the surface of the water with some whzzing and effervescence of hydrogen gas. The heat produced from the reaction may not be sufficient to ignite the hydrogen gas, resulting in no flame, compared to other metals like sodium and potassium where the reaction would be more violet and the metal would quickly catch fire.
What color does an alkali turn in a flame?
it depends on what is in the alkali, sodium, calcium, lithium all turn different colours, I believe lithium turns purple, an alkali is a compound with hydroxide ie sodium hydroxide is NaOH

What is Chemical identification test of lithium carbonate?
One common chemical identification test for lithium carbonate is the flame test. When lithium carbonate is heated in a flame, it produces a characteristic crimson red color. This color is distinctive for lithium ions and can be used to confirm the presence of lithium in a sample.

Metal that bursts into flame when it reacts with water?
Potassium is the only metal (alkali metal) where a flame is present. Lithium and sodium fizz but there is no flame. Caesium, francium and rubidium all explode on contact with water.
What colours do potassium chloride sodium chloride and lithium chloride go in a flame?
Color is determined by the respective cation: Potassium - lilac Sodium - yellow Lithium - red
What color is lithium's flame?
The color of lithium in the flame test is red.
What is lithium's flame color?
The color of lithium in the flame test is red.
What is the color of lithium flame?
The flame of lithium is a bright crimson, or reddish-orange, color.
What is the color of the flame of burning lithium?
The color of lithium in the flame test is red.
What colour flame does lithium produce when it is burnt?
The color of lithium in the flame test is red.
