Write Lewis symbols for the following atoms. (a) Kr; (b) Ge; (c) N; (d) Ga; (e) As; (f) Rb.
(a)
Interpretation:
Interpret Lewis symbol of Kr.
Concept introduction:
Lewis symbol is the representation of the atoms in elemental form found in the periodic table. The element is represented with the universal symbol along with the valence electron present in its valence shell.
The valence electron present in the atom is decided by total number of electrons present in outermost shell.
Answer to Problem 1E
Lewis symbol of Kr is:
Explanation of Solution
In periodic table, Krypton is present in 18 group and in 4 period. The symbol of Krypton is Kr carrying 8 valence electrons in its valence shell.
Thus, the Lewis symbol of Kr is:
