I am having difficulty understanding some differences between an item and a block. This is what I understand so far:
|Stone||x||In placed position, it is a cube / block|
|Dandelion||x||In placed position, it takes up an entire cube/block area and nothing else can be placed on that coordinate|
|Iron Axe||x||It can only be in the player's hand; If the right click (or the set shortcut for placing blocks) is triggered, the axe is either used in a different function or dropped out of the player's hand|
I am mostly confused about whether blocks are also considered items when it is not placed on a coordinate. For example, the block is in a chest, the block is in the player's hand, and the block is in a block with an entity (such as a cobblestone in a furnace). What exactly is considered a block and item?
