the periodic table

Question 1

what do the periods (rows) show?

Answer 1

number of shells an electron has

Question 2

what do the groups (columns) show?

Answer 2

show how many outer electrons an atom has

Question 3

the further away an electron is from the nucleus…..

Answer 3

the more energy it has

Question 4

Answer 4

1-3(more in periods 5 and 6) outer shell electrons

Question 5

non metals electrons arrangement?

Answer 5

4-7

Question 6

type of bonding that occurs with metal x metal?

Answer 6

metallic bonding

Question 7

type of bonding that occurs in non-metals?

Answer 7

covalent bonding

Question 8

Answer 9

poor conductors of electricity

Question 10

metals reaction with acids?

Answer 10

many react with acids

Question 11

non-metals reaction with acids?

Answer 11

do not react with acids

Question 12

physical characteristics of metals?

Answer 12

malleable, shiny, good conductors of electricity, high melting and boiling point

Question 13

physical characteristics of non-metals?

Answer 13

brittle, dull, non-malleable, low melting and boiling points

Question 14

why are metals malleable?

Answer 14

they have layers of ions that can slide over eachother easily

Question 15

group 1 metals are also known as?

Answer 15

alkali metals

Question 16

group 7 elements are known as?

Answer 16

halogens

Question 17

group 8 elements are known as?

Answer 17

noble gases

Question 18

why will elements in the same group have similar chemical properties?

Answer 18

they have the same number of outer shell electrons so will bond and react similarly

Question 19

group 1 metals and group 7 elements react to form what?

Answer 19

ionic compounds

Question 20

the group 1 metals become less or more reactive as you decrease down the group?

Answer 20

more reactive

Question 21

the group 7 elements become less or more reactive as you decrease down the group?

Answer 21

less reactive

Question 22

physical properties of non-metals?

Answer 22

monatomic (exist as single atoms), colourless, non-flammable gases

Question 23

are noble gases stable?

Answer 23

yes- have a full outer shell- very unreactive
