Chemistry - Unit 2 Test

yay!

As energy increases the wavelength becomes ________________

As energy increases the wavelength becomes ________________

shorter

Less energy = _________ wavelength

longer

Low Frequency = _____ energy

Low

Red =

• Long wavelength

• Low Energy

• Low Frequency

Purple/Violet

• Shorter Wavelength

• High Frequency

• High Energy

Coulubmic Attraction

the attraction between oppositely charged particles —> attraction between nucleus and election

Coulubmic Attraction: smaller atom means

nucleus has more charge, meaning the electrons will be pulled in more:

• More Coulubmic attraction

• Distance from rings to the nucleus will be less

Any with more ______ has a stronger attractive force

protons

ionization energy:

energy it takes to remove an electron (most loosely held one)

ionization energy: larger the radius=

easier to remove the electron

electronegativity

the measure of the ability of an atom’s nucleus to attract electrons from a different atom covalent bond.

What trend is this?

ionization Energy/ElectroNegativity

What trend is this?

Atomic Radius

What trend is this?

Columbic Attraction

the color of emitted light is depended on the _______ of the light

wavelength

how do electrons become excited

they absorb energy

when arrows go up the energy of the electrons get ______

absorbed

when arrows go down the energy of the electrons gets ______

emitted into light
