1.4.6 Metallic Bonding Flashcards
1
Q
Metal atoms are tightly packed together in
A
lattice structures
2
Q
When the metal atoms are in lattice structures, the electrons in their outer shells are
A
free to move throughout the structure
3
Q
The free-moving electrons are called
A
‘delocalised electrons’ and they are not bound to their atom
4
Q
When the electrons are delocalised, the metal atoms become
A
positively charged ions
5
Q
The positive charges
A
repel each other and keep the neatly arranged lattice in place
6
Q
The positive metal ions are suspended in a ‘sea’ of delocalised electrons diagram
A
