1(d) Periodic table

Question 1

1.18

understand how elements are arranged in the Periodic Table:
* in order of atomic number
* in groups and periods.

Question 2

1.19

understand how to deduce the electronic configurations of the first 20 elements from
their positions in the Periodic Table

Question 3

1.20

understand how to use electrical conductivity and the acid-base character of oxides to classify elements as metals or non-metals

Answer 3

Metals: Conductor, Alkaline
Non-Metals: Insulator, Acid

Question 4

1.21

identify an element as a metal or a non-metal according to its position in the Periodic
Table

Question 5

1.22

understand how the electronic configuration of a main group element is related to its position in the Periodic Table

Answer 5

The number of electron shells is the same across a period but increases when moving down a group

Question 6

1.23

understand why elements in the same group of the Periodic Table have similar
chemical properties

Answer 6

They have the same number of electrons in their outer shell.

Question 7

1.24

understand why the noble gases (Group 0) do not readily react

Answer 7

atoms have complete outer shells which makes the highly unreactive
