Why don't you start by explaining your initial reasoning? Why do you think that X ends up negatively charged and Y positively charged? What concepts are involved?ikihi said:I think X is negative and Y is positive. Can anyone elaborate on why this may be?

Okay, that's a reasonable interpretation. How might you modify it if you were to assume that the only mobile charges are negative ones (electrons), and that any positive charges (atomic nuclei) are immobile?ikihi said:Not totally sure, but my guess is:
When the positive rod is brought close to X which is touching Y, positive charges are pushed away from the rod across sphere X and onto sphere Y. Now X has more negative charges (electrons) and thus has a negative charge. The positive charge that was pushed onto Y give it an overall positive charge.

Almost. Leave out the the phrase "would make the X-sphere positively charged". The positive rod in close proximity to the X sphere is enough to draw electrons from both spheres towards the rod. The X-sphere in fact gains an overall negative charge with the excess electrons that gather there.ikihi said:Bringing the positive rod towards the X-sphere, would make the X-sphere positively charged and thus draw the elections away from the Y-sphere leaving it positively charged and leaving the X sphere with an excess of negatively charged elections?

Two uncharged metal spheres refer to two spherical objects made of metal that have no net charge. This means that the number of positive and negative charges in each sphere are equal, resulting in a neutral overall charge.
The main difference between two uncharged metal spheres and charged metal spheres is the presence of net charge. Two uncharged metal spheres have equal numbers of positive and negative charges, while charged metal spheres have an excess of either positive or negative charges, resulting in a net charge.
When two uncharged metal spheres are brought into contact, electrons can move freely between them, resulting in an equal distribution of charges on both spheres. This process is known as charge transfer or induction.
Yes, two uncharged metal spheres can become charged through various processes such as friction, conduction, and induction. When these spheres come into contact with charged objects, they can acquire a net charge by either gaining or losing electrons.
The properties of two uncharged metal spheres include having no net charge, being made of conductive material, and being able to transfer charges through contact. They can also be affected by external electric fields, causing them to attract or repel each other depending on their charges.
