State the character of the oxide of period 3 ?
Study the extract of the Periodic Table given below and answer the questions that follow. Give the alphabet corresponding to the element in question. DO NOT repeat an element. 
Which element forms electrovalent compound with G?
In terms of electronic configuration, what the elements of a given period and groups have in common?
Among the elements of the second period, Li to Ne, pick out the element with the highest electro negativity
Fill in the blank
Most electronegative elements belong to ______ group.
Explain
Electronegativity of Cl is higher than S.
The electro negativities (according to Pauling) of the elements in period 3 of the periodic table are as follows.
The elements are arranged in alphabetical order:
Al Cl Mg Na P S Si
1.5 3.0 1.2 0.9 2.1 2.5 1.8
(i) Arrange the elements in the order in which they occur in the periodic table from left to right.
(The group 1 elements first, followed by the group 2 element and so on, up to group 7)
(ii) Choose the word or phrase from the brackets which correctly completes each of the following statements:
(a) The element below sodium in the same group would be expected to have a ______ (lower/higher) electro negativity than sodium and the element above chlorine which would be expected to have a ______ (lower / higher) ionization potential than chlorine.
(b) On moving from left to right in a given period, the number of shells ______ (remains the same / decreases/ increases).
(c) On moving down a group, the number of valence electrons ______ (remains the same / increases/ decreases).
Rewrite the following sentence by using the correct > (greater than) or < (less than) in the blank given :
The electronegativity of iodine is ________ that of chlorine.
The element below sodium in the same group would be expected to have a ______ (lower/higher) electro-negativity than sodium and the element above chlorine would be expected to have a ______ (lower/higher) ionization potential than chlorine.
The changes in the properties of elements on moving from left to right across a period of the Periodic Table. For the property, choose the correct answer.
The electronegativity:
