Question

13. Symbol of atom Li Be B C N O F Ne
Electronegativity 1.0 1.47 2.0 2.5 3.0 3.5 4.0 0
Observe the above table and answer the following questions.
i) What is the electronegativity of inert gas in the above table.
ii) Write the name of the element which has highest electronegativity.
iii) Why does electronegativity increases from left to right in the period ?
iv) Write the name of the element which has least electronegativity in the period ?
SECTION - III

Answer 1

Answer:

1. the inert gas in the above table is known which has electronegativity 4
2. fluorine is the most electronegative in the above table
3. because on moving from left to right in a period the inert anus continuously increases and for an element to become inert it needs electron thus electronegativity increases from left to right
