Answer:
Number of moles is defined as the ratio of given mass in g to the molar mass.The mathematical expression is given as:
Number of moles =Number of moles of compound = 12.7 moles (given)As, 1 mole of any compound is equal to particles.
where, is Avogadro number. Formula for calculating particles is given by:
where, N = number of particles, n = number of moles and is Avogadro number.
Put the values,= or Hence, number of particles of the compound is equal to

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.

A form of
electricity which can attract things is static electricity. Static electricity
is the result of an imbalance between negative and positive charges in an
object. These charges built up o the surface of an object until they find a way
to e released or discharged causing the attraction of things.
