I think the correct answer from the choices listed above is option B. It would be CH3(CH2)14CO2-NA+ that would represent the structure of a soap. A soap<span> is a </span>salt<span> of a </span>fatty acid. <span>Soaps for cleaning are obtained by treating vegetable or animal oils and fats with a strong </span>base<span>, such as </span>sodium hydroxide<span> or </span>potassium hydroxide<span> in an </span>aqueous<span> solution.</span>
The answer is A I believe. If you are refering to the periodic table in this question, then the bottom left are the earth metals, transition metals, etc. The upper right corner are the noble gasses.
here we have to explain the development of the atomic theory by the atomic emission spectrum.
The most important aid in determining the structure of an atom has been study of radiation emitted and absorbed by the elements. The glowing atoms of an element emit radiations.
These are called the atomic spectra. This study helped to understand the structure of the atoms.
To explain the atomic spectra the Bohr's model was introduced. The postulates of the Bohr's model explain the fine spectrum of the atom up to the particle nature of the electrons.
Later some modification on the Bohr's postulates was made to explain the wave nature of the electrons as well. But the atomic spectra is best be understood by the Bohr's atomic model which developed the atomic theory.
Thus the understanding of emission spectrum of atom to develop the atomic theory is explained.

So, compounds of boron contain boron in a positive oxidation state, generally +3. The sum of oxidation numbers of all constituent atoms of a given molecule or ion is equal to zero or the charge of the ion, respectively. ... In most of the stable compounds of boron, its oxidation number is +3
