(a)
Interpretation:
Whether the compound aluminum chloride is held together by ionic or covalent bond is to be stated.
Concept introduction:
The bond which occurs due to the electrostatic attraction in the oppositely charged ions is known as an ionic bond. The compounds that are formed by ionic bonds are known as ionic compounds. The atom which loses the electron is known as cation and the atom which gains the electron is known as anion.
(b)
Interpretation:
Whether the compound water is held together by ionic or covalent bond is to be stated.

- - Classify each compound as ionic or molecular. If it is ionic, determine whether the metal forms only one type of ion or more than one type of ion. (a) CoCl2 (b) CF4 (c) BaSO4 (d) NOarrow_forwardAnswer true or false. (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. (a) A covalent bond is formed between two atoms whose difference in electronegativity is less than 1.9. (b) If the difference in electronegativity between two atoms is zero (they have identical electronegativ- ities),…arrow_forwardAnswer 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. (i) Atoms and the ions derived from…arrow_forward
