Dear Year 12,
I am still recovering from laryngitis and hope to see you on Monday.
For today's lesson we will be starting a new topic
Module 3 - Periodic table and energy
I would like you to read the spec point below
Periodic trends are first studied to extend the
understanding of structure and bonding.
3.1.1 Periodicity
Learners should be able to demonstrate and
apply their knowledge and understanding of:
The structure of the periodic table
(a) the periodic table as the arrangement of
elements:
(i) by increasing atomic (proton) number
(ii) in periods showing repeating trends
in physical and chemical properties
(periodicity)
(iii) in groups having similar chemical properties
Periodic trend in electron configuration
and ionisation energy
(b) (i) the periodic trend in electron configurations
across Periods 2 and 3 (see also 2.2.1 d)
(ii) classification of elements into s-, p- and
d-blocks
(c) first ionisation energy and
successive ionisation energy, and:
(i) explanation of the trend in first ionisation
energies across Periods 2 and 3, and down a
group, in terms of attraction, nuclear charge
and atomic radius
(ii) prediction from successive ionisation
energies of the number of electrons in
each shell of an atom and the group of an
element
I would like you to make notes on the above points ready for Monday's lesson. On MOnday I will give you some exam style questions to test your understanding.
I would use the Chemguide website which always has lots of information to help you understand.
Also Khan academy do some really good videos that explain different concepts in chemistry.
Hope you all have a good weekend
Many Thanks
Miss Chauhan
