PLEASE HELP!!!

3) What do flame tests show about the structure of atoms? (refer to electrons and
energy levels in your answer)
​

Answer 1

Answer:

They show that every element has its own characteristic set of electron energy levels.

Explanation:

According to the Bohr model, electrons in an atom can have only certain allowed energy levels.

When you heat an atom, some of its electrons are "excited" to higher energy levels.

When an electron drops from one level to a lower energy level, it emits a quantum of energy.

The wavelength (colour) of the light depends on the difference in the two energy levels.

We can see only those transitions that correspond to a visible wavelength.

For example, a lithium atom has many different energy levels and many possible transitions, but only a few of them are in the visible region.  The line spectrum of Li shows only a few lines.

The red line is the most intense, so the flame colour of Li is red.

The flame colour of Na is yellow, so it must have a different set of energy levels

Every element has different energy levels and transitions, so every element has a different flame colour.

Answer 2

Movement of electrons from one energy level to another is responsible for the colors observed in flame test.

According to the Bohr model of the atom, electrons are arranged in energy levels within the atom. Energy is absorbed when an electron moves from a lower to a higher energy level. Owing to the fact that electrons are unstable in excited state, the electron quickly returns to ground state giving off a photon of light having  a characteristic wavelength.

This characteristic wavelength occurs as visible light. In a flame test, energy is supplied to the atom in the form of heat. This energy is results in electron transition which is ultimately responsible for the various colors that we observe in a flame test.
