Question 1

Electronegativity pattern

Answer 1

Increase to right
Decrease down
Noble gases don’t have electronegativity value

Question 2

Electronegativity definition

Answer 2

Measure of ability of atom to attract an electron in a covalent bond
Noble Gases don’t have electronegativity

Question 3

Negative electronegativity versus positive electronegativity

Answer 3

Negative charge means strong port because you’re appalling the other electrons towards you.
Positive charge means weak poor because your electrons are getting pulled away from you

Question 4

First electron affinity

Answer 4

Energy released when an electron is added to a neutral atom

Question 5

Second electron affinity

Answer 5

Energy released when an electron is added to a negative ion
Positive because more energy is required to add an electron to a negative ion

Question 6

Electron affinity

Answer 6

Energy change when a neutral atom gains an electron

Question 7

Noble gases versus halogen electron affinity

Answer 7

Noble gases have high positive electron affinity because they need energy to add stuff because they chill

Halogens have high negative electron affinity because they really want to gain an electron something which has negative energy

Question 8

Light lab purpose

Answer 8

What color light is emitter by various metal ions when energized by fkame?
What color light is emitter g various gases when energized by electricity?

Question 9

Atomic emission purpose

Answer 9

What is the relationship between the scale reading and the wavelength

Find equation that relates spectroscopes scale reading to the wavelength the of the lines of color.

P2: use the equation you found in p1 to calculate th and wavelengths
