Which of these best describes metallic bonding?

Metal atoms lose their electrons to a delocalised pool and all of the metal ions are mutually attracted to the delocalised pool, holding all of the ions together.
Metal atoms lose their electrons to non-metal atoms which then creates positive and negative ions which are attracted by electrostatic attraction.
Metal atoms share their electrons in order to fill their electron shells, this causes an attraction between the positive nuclei and shared electrons.

Use one of the following words to fill in the blank:
Soup, grid, lattice, ladder

Since metallically bonded atoms have a delocalised pool of electrons, these electrons are able to conduct ……

Why are metals malleable?

Because the layers of metal slide across each other, rather than breaking the bonds between ions
Because metal atoms themselves are compressible and are moulded into shape
Because metal ions constantly break and reform their bonds, allowing the shape to be moulded
Because metals are very soft and so you can squash them with your thumbs

Why is magnesium a better electrical conductor than sodium?

Group 2 magnesium has two spare electrons to donate to the delocalised pool, whereas, sodium atoms only have one electron to donate. This means there are more electrons to carry the charge.
Group 1 sodium is less electrically conductive because it quickly forms impurities that prevent efficient conduction.
