Periodic Table, Bohr Models, Trends, Flame Test

Front

What are the vertical columns in the Periodic Table called?

Back

Groups.

Front

What is the relationship between wavelength and energy of light?

Back

Shorter wavelengths (like blue light) have higher energy than longer wavelengths (like orange light).

Front

Which element has the largest atomic radius in Group 8?

Back

Radon (Rn).

Front

What happens to electrons during a flame test that causes a color change?

Back

Electrons gain energy and move to an excited state, then release energy as they return to the ground state.

Front

How many electrons can the second energy level hold?

Back

8 electrons.

Front

What is the maximum number of electrons in the third energy level?

Back

8 electrons.

Front

Define atomic radius.

Back

The distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is the significance of the flame test in chemistry?

Back

It is used to identify the presence of certain metal ions based on the color of the flame produced.

Front

What is the Bohr model of the atom?

Back

A model that depicts electrons orbiting the nucleus in defined energy levels.

Front

What is the difference between ground state and excited state of an electron?

Back

Ground state is the lowest energy state, while excited state is when an electron has absorbed energy and moved to a higher energy level.
