what joint is this and what two parts articulate to form it?

sternoclavicular joint which is the joint between the sternal end of the clavicle and clavicular notch of the sternum

how can you differentiate between the acromial and sternal end of the clavicle?

the acromial end is more flattened and squished whereas the sternal end id more compact and bulbus

how to differentiate between the anterior and posterior aspect of the clavicle?

when viewing the bone from a superior view you can see 2/3rds of the bone is convex (curved or rounded outwards) which points anteriorly informing us that is the anterior side.
