WebOct 29, 2024 · erenjaager Answer: metallic bond, force that holds atoms together in a metallic substance. The atoms that the electrons leave behind become positive ions, and the interaction between such ions and valence electrons gives rise to the cohesive or binding force that holds the metallic crystal together. Explanation hope this helps WebJul 12, 2024 · A valuable clue to the nature of bonding in metals is provided by their ability to conduct electricity. Electrons can be fed into one end of a metal wire and removed from the other end without causing any obvious change in the physical and chemical properties of … To account for this freedom of movement modern theories of metallic bonding … We would like to show you a description here but the site won’t allow us.
WebMetallic bonding in sodium Metals tend to have high melting points and boiling points suggesting strong bonds between the atoms. Even a metal like sodium (melting point … WebMetallic Bonding (animation) The outermost electrons in a metal atom can move freely between nearby positive metal atom nuclei as if they were a sea of negative charge. These electrons are attracted to all the positively charged nuclei, not just one. The collective attraction between the sea of electrons and the lattice of nuclei holds the ...
