coulombic attraction and emission spectra

Front

What is Coulombic attraction?

Back

Coulombic attraction is the force of attraction between positively charged protons in the nucleus and negatively charged electrons surrounding the nucleus.

Front

What happens to Coulombic attraction as the distance between protons and electrons increases?

Back

The force of attraction decreases as the distance increases.

Front

What is the significance of the periodic table's periods?

Back

Periods in the periodic table represent the energy levels of electrons in an atom.

Front

Which color of light has the highest energy?

Back

Violet light has the highest energy among visible light colors.

Front

What is an alkali metal?

Back

Alkali metals are elements in Group 1 of the periodic table, characterized by having one electron in their outermost shell.

Front

How many periods are there in the periodic table?

Back

There are 7 periods in the periodic table.

Front

What is the relationship between energy levels and electron removal?

Back

Electrons in higher energy levels are farther from the nucleus and experience less Coulombic attraction, making them easier to remove.

Front

What is the trend of ionization energy across a period?

Back

Ionization energy generally increases across a period from left to right.

Front

What is the trend of atomic radius down a group?

Back

Atomic radius increases down a group due to the addition of energy levels.

Front

What is the emission spectrum?

Back

The emission spectrum is the spectrum of light emitted by a substance when its electrons transition from a higher energy level to a lower energy level.
