Select the correct answer from the choices A, B, C and D which is given.

Write only the letter corresponding to the correct answer .

Among the period 2 element the one which has high electron affinity is:

• Lithium

   

• Carbon

• Fluorine

• Neon

Consider the selection of the periodic table given below:

Group Number	IA 1	IIA 2	IIIA 13	IVA 14	VA 15	VIA 16	VIIA 17	0 18
2nd Period	Li		D			O	J	Ne
	A	Mg	E	Si		H	K
	B	C		F	G			L

 

Note: IN this table B does not represent boron;

C does not represent Carbon

F does not represent fluorine

H does not represent Hydrogen

K does not represent potassium.

You must see the position of the element in the periodic table.

Some elements are given in their own symbol and position in the periodic table, while  others are shown with a letter. With reference to the table;

i)    Which is the most electronegative?

ii)    How many valence electrons are present G?

iii)  Write the formula of the compound between B and H.

iv) In the compound formed between F and J, what type of bond will be formed? Covalent

v) Draw the electron dot structure for the compound formed between C and K : diagram

Define Ionization potential.

Select the correct answer from the choice A, B,C and D which are given:

Among the following the one which  is composed of all the three kinds of bond (ionic, covalent and coordinate bond)is:

• Sodium chloride

• Ammonia

• Carbon tetrachloride

• Ammonium chloride
  
  

Methane is the first member of alkane when it is treated with an excess of chlorine in the presence of diffused sunlight forms carbon tetrachloride. Draw the appropriate structural formula of carbon tetrachloride and state the type of bond present in it.
