Covalent Bonds Flashcards
1
Q
How are ‘Covalent Bonds’ formed?
A
- Through most non-metal compounds being held together by pairs of electrons
2
Q
Where do the electrons in these bonds come from?
A
- The outermost electron shells of the atoms
3
Q
What do ‘Dot and Cross’ diagrams represent?
A
- The electrons so you can see which atom each electron is from
4
Q
Where can ‘Covalent’ Bonds form?
A
- Between atoms of different non-metal elements because all these elements are short of having a full outermost shell of electrons
5
Q
How is a ‘Double’ bond formed?
A
- Atoms can share more than one pair of electrons if this is needed for each atom to have a full outermost shell. Two pair of shared electrons form a double bond:
