(a)
Interpretation:
Whether the valence electrons are more, fewer or the same for first element compared to the second one in the following pair -
Concept Introduction:
The electrons present in the outermost shell of the atom are known as valence electrons.
Valence electrons are important because:
- The valence electrons decide the reactivity of an element.
- Except inner
transition elements valence electrons are present in s or p subshells of elements. - For inner transition elements incompletely filled d or f subshells electrons are considered as valence electrons.
- The group number is similar to number of valence electrons of an atom.
The ways in which electrons are arranged into various orbitals around the nuclei of atoms is called electronic configuration.
(b)
Interpretation:
Whether the valence electrons are more, few or same for first element compared to the second one in the following pair -
