C3.5 - Covalent Bonding (Finished) Flashcards
1
Q
Why are covalent bonds very strong?
A
The positively charged nuclei are attracted to the shared pair of electrons
2
Q
Where does covalent bonding happen?
A
In compounds of non metals (H2O) and non metal elements (Cl2 bonded to themselves)
3
Q
What is the limitation of displayed formula?
A
It dosent show where each electron came from or the 3D structure
4
Q
What is the limitation of 3D models of atoms?
A
- They get confusing quickly when dealing with large arrangements
- Don’t show where the electrons in the binds have come from
5
Q
What are the strong bonds between the atoms sharing electrons called?
A
Covalent bonds
6
Q
What is a displayed formula like and what is it good for?
A
It shows covalent bonds as single lines between atoms which is good for showing how atoms are connected together in large molecules
