6 shows that the element is in the 6 period,
6p² shows that the element is in the 14th group. (1 and 2 groups have s -electrons as last ones, 13 group has s²p¹, and 14 group has s²p²)
The element is Pb.

Answer:
Oxidation–reduction or redox reactions are reactions that involve the transfer of electrons between chemical species (check out this article on redox reactions if you want a refresher!). The equations for oxidation-reduction reactions must be balanced for both mass and charge, which can make them challenging to balance by inspection alone. In this article, we’ll learn about the half-reaction method of balancing, a helpful procedure for balancing the equations of redox reactions occurring in aqueous solution.

Answer:
The volume of the marble is 10 mL.
Explanation:
From the question given above, the following data were obtained:
Volume of water = 10 mL
Rise in water = 10 mL
Volume of marble =.?
From the question given above, the water level rise by 10 mL when a glass marble was placed into the water.
This is equally the volume of the marble as the marble will displace it's volume when placed in the water according to Archimedes' principle.
Therefore,
Rise in water = 10 mL = volume of marble.
