Question 19

list the alkali metals

Answer 19

Lithium (Li), Sodium (Na), Potassium (K), Rubldlum (Rb), Ceslum (Cs), Francium (Fr)

Question 20

list the alkaline earth metals

Answer 20

Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), Radium (Ra)

Question 21

list the halogens

Answer 21

Fluorine (F), Chlorine (Cl), Bromine (Br), Iodine (I), Astatine (At), Tennessine (Ts)

Question 22

list the noble gases

Answer 22

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

Question 23

how is line-emission spectra created?

Answer 23

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

Question 24

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

Answer 24

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

Question 25

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

Answer 25

the fall levels of the electrons

Question 26

how do metals react? (what the electrons do)

Answer 26

losing all their valence electrons

Question 27

why do noble gases not react?

Answer 27

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

Question 28

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

Answer 28

adding valence electrons until they have a full shell

Question 29

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