When an element is heated in a bunsen burner flame, the resulting color of the flame changes can be used to identify the element. what causes the colored light that is observed? (2 points) the protons and neutrons move faster at higher temperatures and their collisions produce light energy. when an electron moves from a higher to lower orbital, energy is released as waves of light. an endothermic reaction occurs, which converts the thermal energy to light energy. upon heating, the element reacts with oxygen to produce a gaseous compound with a specific color.

When an electron moves from a higher to lower orbital, energy is released as waves of light.

Explanation:

The energy from the flame excites the electrons to orbitals of higher energy.

When the electrons drop to lower-energy orbitals, they release the excess energy as light waves.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
