Chapter 11: The Periodic Table.
11.1 to 11.3 Arrangement of Elements in the Periodic Table
(SIO) Students should be able to:
(a) Describe the periodic table as arrangement of elements in the order of increasing proton number.
(b) Describe how the position of the element is related to the proton number and electronic structure.
(c) Describe the relationship between group number and the ionic charge of an element.
(d) Explain the similarities between the elements in the same group in terms of electronic structure.
(e) Describe the change from metallic to non-metallic character from left to right of the period.
(f) Describe the relationship between group number, number of valency electrons and metallic and nonmetallic character.
(g) Predict the properties of elements in Group I and Group VII.
1. The Modern Periodic table have the element arranged according to their _____________
numbers. Previously the defunct Mendeleev Periodic table have the elements arranged
according to _______________ numbers.
2. Elements can be found arranged in columns. The column is known as _____________. The
elements in the same Group will

5. Across the Period, the elements gradually decreases in _____________ properties and increases
in _____________ properties.
6. In general, metals tend to ______________ electron(s) in a chemical reaction to form
___________ ions whereas non-metals tends to _______________ electron(s) in a chemical
reaction to form _________________ ions.
Quick check 1: Element X has proton number of 35. Element Y has a proton number of 37.
(a) What group and period they belong to?
(b) What are elements they belong to?
(c) How many electron shells do they have? How many electrons do they have in their outermost
shell?
(d) What type of compound X will from with hydrogen and sodium respectively?
(e) Write down their ion. Write down the formula of the compounds formed when X reacts with
calcium and when Y reacts with oxygen.
(f) Does X exist as simple covalent molecule or giant covalent molecules or giant ionic structure?
(g) What is similarity between Y and sodium? Predict the chemical reactivity of Y when compared to
sodium.
