Periodic table – Group 1 The alkali metals have a silvery, shiny surface when they are first cut. However, this goes dull very quickly as the metals reacts with the oxygen in the air. e.g. sodium + oxygen sodium oxide 4Na(s) + O2(g) 2Na2O(s) Lithium, sodium and pota...

For GCSE Chemistry it is vital that students have a good understanding of the periodic table. In this quiz we take a look at how the periodic table is organised into groups and periods, and also at some of the information we can get about elements from their position in the table. ...
General Trends of the Periodic Table Atoms are arranged by their atomic numbers. Fr is the most active Metal (botton left) – circle it F is the most active Nonmetal (top right, but not a noble gas)– circle it Size increases downward and to the left Now take the Online Quiz There ar...
To do well in GCSE chemistry, students must familiarise themselves with the Periodic Table. In this quiz, written by teachers for pupils in Year 10 and Year 11, we revise the elements in Group One. Some of the most reactive ones are found there - what el
For a multiple access communication system it is desirable to have a set of sequences such that (a) each sequence has as peaky an auto-correlation as possible and (b) each pair of sequence has as negligible a cross-correlation as possible. Peakiness of the auto-correlation of a sequence ...

Whereas the larger value of ¯S f gives improvement in average productivity for all values of time delay. Dilution rate (D) cycling gives an improvement in average productivity particularly for larger time delay in μ . This improvement in average productivity is obtained only at smaller value ...
In this case, the conventional approach based on the asymptotic Landau–Zener formula for transition probabilities is not applicable. We develop a novel adiabatic-impulse model for the evolution of the system and derive the resonance conditions. Additionally, we derive analytical results based on the...
