The atomic number for iodine (I) = 53

The electron for I is:

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁵

Now, among the noble gases, Krypton (Kr) has an atomic number 36. Thus we can write:

I = [1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ ] 5s² 4d¹⁰ 5p⁵

I = [Kr] 5s² 4d¹⁰ 5p⁵

(or)

I = [Kr]  4d¹⁰ 5s² 5p⁵

How many silver atoms are there in 3.78g of silver?
oksian1 [2.3K]

2.1 x 10²²atoms

Explanation:

Given parameters:

Mass of silver = 3.78g

Unknown:

Number of atoms of silver = ?

Solution:

To solve this problem, we first find the number of moles of the silver from the given mass.

  Number of moles = \frac{Mass}{Molar mass}

Molar mass of Ag  = 108g/mole

   Number of moles = \frac{3.78}{108}  = 0.035mole

Now;

  A mole of any substance contains 6.02 x 10²³ atoms

     0.035 moles of Ag will contain 0.035 x 6.02 x 10²³ = 2.1 x 10²²atoms
