Question

1. What is the electron configuration of the first three noble gases?
2. Why noble gases are unreactive, why they do not form molecules?
3. What is the trend shown in their boiling points down the group?

Answer 1

Answer:

1) helium-2

2)neon-2,8

3)argon-2,8,8

Noble gases are interactive because they are already stabled due to octate rule and also dupleate.

Answer 2

Answer:

Q1 electronic configuration of first three noble gases are :

1. helium: 2

2.neon : 2,8

3 2,8,8

Q2. Noble gases are unreactive because their outermost shell already have the 8 electrons and because of this noble gases neither loose electrons nor gain, they are constant, that is why they are unreactive

Q3 the boiling point of noble gases increases as their atomic masses increases
