(a)
Interpretation:
The chemical formula for the given molecule should be identified.
Concept introduction:
According to the nomenclature, when two nonmetals are present in the given compound the name of the compound is given as follows, For example, HCl. According to the name of the compound, first give the name for the hydrogen followed by the second element, changing the ending of its name to –ide. Chlorine called as chloride. Therefore HCl is hydrogen chloride. Similarly, HI is hydrogen iodide. SiC is silicon carbide.
One pair of elements to form several different binary molecular compounds. In these cases, using of Greek prefixes to denote the number of atoms of each element present.
Greek prefixes are given below,
If prefix mono substituted is generally omitted for the first element. For example, SO2 is named sulfur dioxide, is not monosulfur dioxide. Moreover, only one atom in a prefix for the first element, no needs to mention mono or di etc.… In addition, for ease of pronunciation, we usually eliminate the last letter of a prefix that ends in o or a when naming an oxide. Thus, N2O5 is dinitrogen pentoxide, rather than dinitrogen pentaoxide.
If any halogens are present in the molecule in suffix, the name of the halogens as follows.

- Answer true or false. (a) The octet rule refers to the chemical bonding patterns of the first eight elements of the Periodic Table. (b) The octet rule refers to the tendency of certain elements to react in such a way that they achieve an outer shell of eight valence electrons. (c) In gaining electrons, an atom becomes a positively charged ion called a cation. (d) When an atom forms an ion, only the number of valence electrons changes; the number of protons and neutrons in the nucleus does not change. (e) In forming ions, Group 2A elements typically lose two electrons to become cations with a charge of 12. (f) In forming an ion, a sodium atom (1s22s22p63s1) completes its valence shell by adding one electron to fill its 3s shell (1s22s22p63s2). (g) The elements of Group 6A typically react by ac- cepting two electrons to become anions with a charge of 22. (h) With the exception of hydrogen, the octet rule applies to all elements in periods 1, 2, and 3.

(a) The name of a binary ionic compound consists of the name of the positive ion followed by the name of the negative ion. (b) In naming binary ionic compounds, it is necessary to state the number of each ion present in the compound. (c) The formula of aluminum oxide is Al2 O3 . (d) Both copper(II) oxide and cupric oxide are acceptable names for CuO. (e) The systematic name for Fe2 O3 is iron(II) oxide. (f) The systematic name for FeCO3 is iron carbonate. (g) The systematic name for NaH2PO4 is sodium di- hydrogen phosphate. (h) The systematic name for K2HPO4 is dipotassium hydrogen phosphate. (i) The systematic name for Na2O is sodium oxide. (j) The systematic name for PCl3 is potassium chloride. (k) The formula of ammonium carbonate is NH4CO3. 39.
