the electronegativities 1.0, 2.0, 1.5 and
3.0, respectively on the Pauling scale.
​

Answer 1

Explanation:

Lead. C...... Forgot about it

Answer 2

Answer:

1)Li, B, C, Be and N belong to the same period .

2) as we move across a period from left to right in the periodic table , the effective nuecler charge increases steadily and therefore electronegativt

increases hence , the elements Li ,B, C, Be and N have

the electronegativities 1.0, 2.0, 1.5 and

3.0, respectively on the Pauling scale.
