Answer 3

Chemical Bonds in NH3, Mg3N2, N2, SO2, BR2

- NH3: Ammonia (NH3) forms a covalent bond. It consists of one nitrogen atom bonded to three hydrogen atoms. The nitrogen atom shares its three valence electrons with the three hydrogen atoms, resulting in a covalent bond. [[1]] - Mg3N2: Magnesium nitride (Mg3N2) forms an ionic bond. It consists of three magnesium atoms bonded to two nitrogen atoms. The magnesium atoms transfer two electrons each to the nitrogen atoms, resulting in an ionic bond. [[2]] - N2: Nitrogen gas (N2) forms a covalent bond. It consists of two nitrogen atoms bonded together by a triple covalent bond. The two nitrogen atoms share six electrons, resulting in a covalent bond. [[3]] - SO2: Sulfur dioxide (SO2) forms a covalent bond. It consists of one sulfur atom bonded to two oxygen atoms. The sulfur atom shares its two valence electrons with the two oxygen atoms, resulting in a covalent bond. [[4]] - BR2: Bromine (Br2) forms a covalent bond. It consists of two bromine atoms bonded together by a single covalent bond. The two bromine atoms share one electron each, resulting in a covalent bond. [[5]]

Odd One Out in the Series

1) In the series H2S, O2, H2O, SO3, the odd one out is O2. The other compounds are all formed by the combination of hydrogen and a nonmetal, while O2 is a diatomic molecule of oxygen. [[6]]

2) In the series MgO, CO, NO, P2O5, the odd one out is CO. The other compounds are all oxides, while CO is a carbon monoxide molecule. [[7]]

Number of Bonding Electron Pairs

1) NH3: Ammonia (NH3) has three bonding electron pairs. The nitrogen atom forms three covalent bonds with three hydrogen atoms, resulting in three bonding electron pairs. [[8]] 2) N2: Nitrogen gas (N2) has three bonding electron pairs. The two nitrogen atoms form a triple covalent bond, sharing three electron pairs. [[9]] 3) F2: Fluorine gas (F2) has one bonding electron pair. The two fluorine atoms form a single covalent bond, sharing one electron pair. [[10]] 4) SO2: Sulfur dioxide (SO2) has two bonding electron pairs. The sulfur atom forms two covalent bonds with two oxygen atoms, resulting in two bonding electron pairs. [[11]]

Types of Chemical Bonds in Different Crystal Lattices

- Ionic Crystal Lattice: In an ionic crystal lattice, such as NaCl (sodium chloride), the bonding is primarily ionic. The lattice is held together by the electrostatic attraction between positively charged sodium ions and negatively charged chloride ions. [[12]] - Atomic Crystal Lattice: In an atomic crystal lattice, such as diamond, the bonding is primarily covalent. The lattice is held together by a network of covalent bonds between carbon atoms. [[13]] - Molecular Crystal Lattice: In a molecular crystal lattice, such as ice (solid water), the bonding is primarily covalent. The lattice is held together by intermolecular forces between water molecules, which are formed by covalent bonds. [[14]] - Metallic Crystal Lattice: In a metallic crystal lattice, such as copper or iron, the bonding is metallic. The lattice is held together by a sea of delocalized electrons that are shared by all the metal atoms. [[15]]
