Question

Fill in the blanks (1) Sodium atom________an electron to attain the electronic configuration of the element _______​

Answer 1

The maximum number of electrons in each shell is calculated by the 2n

2

formula.

∙ Atomic number of any neutral element represents the number of protons or electrons present in the atom.

∙ Electrons are filled in the shell or orbits with an increase in energy level.

K shell, n = 1 Number of electrons = 2(1)

2

=2

L shell, n = 2 Number of electrons = 2(2)

2

=8

M shell, n = 3 Number of electrons = 3(3)

2

=18 and so on.

The atomic number of sodium is 11, So there are 11 electrons and its electronic configuration is 2(K), 8(L), 1(M).

Answer 2

Answer:

sodium atom looses an electron to attend the electronic configuration of the element Chlorine
