hard
it is a common observation that metals of group 1 i.e., li,na,k,rb,cs and group 2,be,mg,ca,sr,ba are soft.similarly the metals of p-block elements in lower parts of groups are also soft but harder than alkali and alkaline earth which are s-block. the metals of d-and f-block elements are called hard metals.
One is hard one is soft
Not all metals are hard, as some metals like gold and lead are relatively soft. Additionally, while many metals have high melting points, some metals like mercury have low melting points. The properties of metals can vary widely depending on the specific metal in question.
Inner transiton metals and inner transiton elements... So both a and c
Lanthanides and actinides are generally less reactive than alkali or alkaline earth metals. They tend to form stable compounds and exhibit a variety of oxidation states due to the presence of f-orbitals in their electronic configuration. Actinides may show greater reactivity due to the availability of f-orbitals for bonding.
Spoons are not soft, but they are smooth. They are made out of hard metals like aluminum, steel and other metals.
No. Some metals are hard, but some are soft.
Alkali earth metals are relatively soft compared to transition metals, like iron or copper. They can be cut with a knife due to their low hardness.

One is hard one is soft
Aluminum is not as hard as some other metals, such as steel or titanium. It is relatively soft and lightweight compared to these metals.
inner transistor metals
They are silvery metals that conduct electricity
Lanthanides exist as solids at room temperature and pressure. They have metallic properties and are typically soft, malleable, and ductile.
They are silvery metals that conduct electricity
They are silvery metals that conduct electricity.
Examples: lanthanides, atinides, halogens, noble gases, platinum metals, alkali metals, etc.
