1 Answer

Answer :

I’m assuming you haven’t gotten an answer to your question for 2 months because you’re question isn’t specific and doesn’t really make sense (no offense…) What are you looking you for? I’d be glad to help if I can, I’m a chem eng major and helping ppl with their chemistry helps me remember and get better at it!

(1) they contain free electrons Explanation: Metals typically consist of closepacked atoms, meaning that the atoms are arranged like closely packed spheres. Two packing motifs are common, one being bodycentered cubic wherein each metal atom is surrounded by eight equivalent atoms. The other main motif is face-centered cubic where the metal atoms are surrounded by six neighboring atoms. Several metals adopt both structures, depending on the temperature.
