Some metals are soft because they have less delocalised electrons in between the layers of positive ions. the delocalised electrons stop the repulsion between the two layers of positive ions. in soft metals, less delocalised electrons are present. this leads to smaller forces of attractions. An example of soft metal is lead.
D-block metals are hard metals. this is because they have more delocalised electrons in between the layers of positive ions. more delocalised electron (negatively charged) are strongly attracted to the layers of positive ions
plz mark brainliest
