Question

How and when elements in the powder emit different colors of light at a subatomic level

Answer 1

Elements in powdered form emit different colors of light at a subatomic level due to the excitation of electrons. The emission of light can be used to identify the presence of elements in a substance.

Step-by-step explanation:

When elements are in a powdered form and heated, they emit different colors of light at a subatomic level. This emission of light is due to the excitation of electrons in the atoms. Each element has a unique atomic emission spectrum, which is the pattern of lines formed when light from the element passes through a prism to separate it into different frequencies. The specific wavelengths or colors of light emitted by an element can be used to identify the presence of that element in a substance or compound.

Answer 2

Elements in the powder emit different colors of light due to :

• When we ,introduce heat to the atom,, the electrons within the atoms ,becomes excited, , thus elevating to ,their highest energy ,level.

,

• When the ,heat subsides,, electrons also ,return to lower energy ,level.

,

• When this happens , they ,discharge energy in the form of light,, as a results they ,produce different colours of light.,

,

• This is due to different energy between two levels.
