the periodic table

Question 1

why are the noble gases in group zero unreactive?

Answer 1

their very stable electronic structure

Question 2

Group 1

Answer 2

alkali metals

Question 3

boiling and melting points-group 1

Answer 3

decrease as you go down the group

Question 4

reactivity of group 1

Answer 4

increases as you go down the group

Question 5

what happens when the metals in group 1 react with water?

Answer 5

produces hydrogen and an alkaline solution containing the metal hydroxide

Question 6

what ions does group 1 form?

Answer 6

1+ ions
-generally white and dissolve in water, giving colorless solutions

Question 7

melting points- transition metals

Answer 7

compared with the alkali metals, transition metals have a much higher melting point, they are also stronger and harder but are much less reactive.

Question 8

transition metals reacting with water or oxygen

Answer 8

they do not react vigorously

Question 9

what are transition metals important for?

Answer 9

industrial catalysts

Question 10

what ions do halogens form?

Answer 10

with a single negative charge in their ionic compounds with metals

Question 11

what type of bonding do halogens form?

Answer 11

covalent bonding

Question 12

reactivity of group 7 (halogens)

Answer 12

decreases as you go down the group

Question 13

reactivity within groups

Answer 13

-larger atoms lose electrons more easily as you go down the group
-larger atoms gain electrons less easily as you go down the group
