SIMPLE MOLECULAR STRUCTURES Flashcards
1
Q
What is a covalent bond?
A
The strong electrostatic connection between two nuclei and a shared pair of electrons.
2
Q
What is the boil and melt point of simple molecular structures?
A
LOW
3
Q
explain the melt/boil point…
A
- simple covalent molecular
- strong covalent bonds
- weak IMF so little energy to overcome
4
Q
as the molecular mass increases there are more electrons and protons so the IMF …………….. .
A
INCREASES
5
Q
Do simple molecular substances conduct electricity?
A
No
6
Q
Explain the conductivity.
A
no mobile delocalised electrons (no ions)
