Check its reactivity the most reactive is the most metallic. And remember in third group of the periodic table contains all metals
The given elements put into an equation using their symbols are as follows:
Pb +

=

+ Ag
Since there are 2 Pb on the right side of the equation, you would change the coefficient of Pb on the left side to 2:
2Pb +

=

+ Ag
Since there are 2 Acetate on the right side of the equation, you would change the coefficient of Silver Acetate on the left side to 2:
2Pb +

=

+ Ag
Now there are 2 Silver on the left side, so you change the coefficient of Silver on the right side to 2:
2Pb +

=

+ 2Ag
That is your final equation
The coefficients are 2 + 2 = 1 + 2

Answer:
B. Able to be lost or gained in chemical reactions.
Flat as more oxygen and water can react over it think of it like this would a cube rust faster than a sheet
