Question

(b) Write the valence shell and valence electron of the following
(i) Aluminium
(ii) Titanium
I
(iii) Oxygen
(iv) Sulphur
(v) Neon​

Answer 1

$\huge{\bf{\green{\fcolorbox{yellow}{black}{\underline{\color{yellow}{Answer}}}}}}$

(i) Aluminium has 3 valence electrons.

(ii) Titanium has four valence electrons.

(iii) Since oxygen is in group 6 it means that it has 6 valence electrons.

(iv) Again, consider sulfur, S, which, based on its electron configuration, has 6 valence electrons.

(v)[He]2s²2p⁶

HOPE THIS IS HELPFUL !!
