21
Q

list the halogens

A

22
Q

list the noble gases

A

Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), Radon (Rn), Oganesson (Og

23
Q

how is line-emission spectra created?

A

electricity is applied to electrons in their normal state and the electrons move up a higher energy level (their excited state).

24
Q

what happens when the electrons fall after they move up a higher energy level?

A

they released electromagnetic energy, and a photon, in the form of light.

25
Q

what determines the different colors of light? (includes infrared and ultraviolet)

A

the fall levels of the electrons

26
Q

how do metals react? (what the electrons do)

A

losing all their valence electrons

27
Q

why do noble gases not react?

A

have full valence shells so they don’t need to attract additional electrons

28
Q

how do non-metals react? (what the electrons do)

A

adding valence electrons until they have a full shell

29
Q

how is the period number related to the energy level of the valence electrons?

A
