Metallic Bonding Flashcards
1
Q
what are the electrons like in the outer shell of metal atoms?
A
delocalised
2
Q
where are there strong electrostatic forces of attraction?
A
between the positive metal ions and negative shared electrons
3
Q
why do metals have high melting and boiling points?
A
the electrostatic forces are strong so need lots of energy to be broken
4
Q
what are metals like at room temp?
A
shiny solids
5
Q
are they soluble in water?
A
no
6
Q
why are metals denser than non-metals?
A
the ions in the metallic structure are packed closely together
7
Q
how is metal malleable?
A
the layers or atom in a pure metal can slide over each other
8
Q
why are metals good conductors of heat and electricity?
A
the delocalised electrons carry current and thermal heat energy through the material
