Network, Coordinate Covalent, & Metallic Bonding

What is the basis of a metallic bond?

• the attraction of neutral metal atoms.
• the attraction between protons and neutrons.
• the attraction between positive metal ions and interlocking electrons.
• the attraction between positive metal ions and free floating electrons.

What is the ability of a substance to be pulled into a thin strand?

• Malleability
• Ductility 
• Conductivity
• Solubility

Why do metals have high melting points?

• They don't
• The negatively charged electrons act as a glue to hold the positively charged ions together.
• All the electrons become delocalised

forms when one atom donates a pair of electrons to be shared with an atom or ion that needs two electrons to become stable

• coordinate covalent bond

• covalent bond

• ductility
• malleability
• conductivity

Why do metallic compounds conduct electricity as solids?

• core electrons are mobile, allowing electricity to flow through the metal

• valence electrons are mobile, allowing electricity to flow through the metal

• protons are mobile, allowing electricity to flow through the metal

• the metal cations are mobile, allowing electricity to flow through the metal
