Electronegativity of an element refers to its tendency to attract a pair of electrons towards itself.
An ionic bond is formed by the complete transfer of electrons from one element to the other. This implies that the combining elements should exhibit a large difference in their electronegativity values.
In contrast, a covalent bond is formed by a mutual sharing of electrons between 2 atoms that do not differ much in their electronegativity values.
Given Electronegativity values are:
A = 0.75
B = 3.2
C = 3.7
a) The difference in electronegativity is the greatest between A and C i.e. 3.7 - 0.75 = 2.95. Hence, AC will form an ionic bond
b) The difference is least between B and C i.e. 3.7 -3.2 = 0.5. Hence, BC will form a covalent bond
c) In AC, C is more electronegative than A
C = anion and A = cation
Answer:
A) Fission
Explanation:
Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.
Jamal’s hair is behaving that way because he is in a cold area.
Answer:
Explanation:
Assume Ksp of 
=
( it is general value ,i took it because not given in question)
molar solubilty means how much maximum mole of lead thiocynate is dissolved in one litre of solvent.
Ksp=solubility product;
Lets molar solubilty of 
is S then

There are only 2 organic compounds present, C2H6 and CH4. The rest are all inorganic compounds.
