Monatomic Elemys & LDF

Question 1

What type of elements are noble gases
And why are they stable

Answer 1

Noble gases exist as monoatomic elements meaning they exist as single atoms
This is due to them having full outer electron shells making them very stable

Question 2

Noble gases don’t form chemical bonds so what do they do?

Answer 2

Turn into liquid and solids at low temperature are there are weak forces of attraction holding atoms together known as LDF

Question 3

What can happen to the electron distribution

Answer 3

At anytime the electron distribution in atoms may be such that one side is slightly negative and one side is slight positively charged

Question 4

What does unequal distribution lead to

Answer 4

A temporary dipoles being created

Question 5

What does unequal distribution lead to

Answer 5

A temporary dipoles being created

Question 6

Explain the process of induced dipoles

Answer 6

The end of the - atom will repel the end of the electrons on the -e on the adjacent atoms

Causing temporary dipoles called indiced dipoles

Question 7

What’s attracted to what

Answer 7

The + end of a dipole on one atom is attracted to the - end of a dipole on a nearby atoms

Question 8

What do the more electrons means

Answer 8

The strength of LDF between atoms is proportional to the no of e

The more e the more stronger LDF
This means an increase in the melting and boiling point of noble gases as you descend end a group
