    hi..i'm very new to chemistry...can someone please explain what are the differences and similiarities between a metallic bond and an ionic bond please? thx...

    metalic bond is like the electrons have been given away and bolengs to every atom in the metal. Like on second it belongs to atom A next B after that C and so on. Ionic is the electrons locked onto a singel atom and wont change, and its the electric force that keeps it toghater.

    this is why you can bend metals but not salts

    ......i've read about that when the atomic size of an alkali metal increases, but the metallic bonding between the atoms get weaker...why?

    EDIT: does it mean the bigger the atoms of an alkali metal, the further the nucleus is from the valence electron, and that makes the metallic bonds get weaker?

    Although it's true that the valence electrons are further away from the nucleus, it's more to do with the extra pq shell of electrons shielding the nucleur charge from the delocalised electrons around it. So essentially there is less electrostatic attraction between the opposite charges which gives a weaker bond
