(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.

(d)
Interpretation:
Interpret the Lewis symbol of Ga.
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 Ga is:
Explanation of Solution
In periodic table, Gallium is present in 13 group and in 4 period. The symbol of Gallium is Ga carrying 3 valence electrons in its valence shell.
Thus, Lewis symbol of Ga is:

(e)
Interpretation:
Interpret the Lewis symbol of As.
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 As is:
Explanation of Solution
In periodic table, Arsenic is present in 15 group and in 4 period. The symbol of Arsenic is As carrying 5 valence electrons in its valence shell.
Thus, the Lewis symbol of As is:

- Q9. The insecticide DDT (in the box below) is useful in controlling mosquito populations and has low toxicity to humans, but is dangerous to birds and fish. Hoping to alleviate the dangers, little Johnny Whizbang, an aspiring chemist, proposes a new version of DDT ("Bromo-DDT") and shows his synthesis to his boss. Will Johnny Whizbang's synthesis work? Or will he be fired? Assume there is an excess of bromine and polybrominated products can be separated. Explain why.
