Question

eighteen elements is given in 'Table 4.1.
uestions
1. Write the distribution of electrons
in carbon and sodium atoms.
2. If K and I shells of an atom are
full, then what would be the total
number of electrons in the atom?
4.4 Valency
We have learnt how the lectrons in an atom
are arranged in diff hells/orbits. Thvalency ​

Answer 1

Explanation:

question 1.

Carbon has 6 electrons.

so,

1s*2 ,2s*2 2p*2

Sodium has 11 electrons.

so,

1s*2, 2s*2 2p*6, 3s*1

question 2.

as k shell has 2 electrons and l shell has the tendency of 6 electrons so, total electrons will be 8.

question 3 is not complete.

mark as brainliest as I also gave explanation that how I solved.......!
