Bonding Flashcards
Covalent bonds are what?
Two atoms sharing their outer electrons
How are covalent bonds held?
The attraction of the nuclei to the shared electrons holds the atoms together
A small number of atoms in the covalent structure is known as what?
Covalent molecule
How many atoms are there in a covalent network?
An unlimited amount
Metallic bonding is held how?
The attraction of Positive ions in a sea of delocalised electrons holds the structure
What forms ionic bonds
Metal and non-metal atoms
How is an ionic bond formed
The transfer of electrons from the metal atom to the non-metal atom
Which ion (metal or non-metal) is positive
Metal
How are ionic bonds attracted
The opposite charge attracts the ions
An example of an ionic lattice?
Salt
An example of covalent network
Sand
Covalent bonding is between what atoms
