According to his equation, Al2O3 is slightly nore ionic than covalent. The higher charges on Al and O make their bonding more covalent and with higher Coulombic attraction between the positive and negative ions those of a binary compound involving ions of lower charges (e.g. CaF2, NaCl).

According to the official answer key, PbO isn't ionic. Although I know this distinction between ionic and covalent isn't defined sharply. But Pb is a metal and Oxygen is a non-metal.

Compounds containing two elements (so called binary compounds) can either have ionic or covalent bonding. If a compound is made from a metal and a non-metal, its bonding will be ionic. If a compound is made from two non-metals, its bonding will be covalent.

Ionic compounds consist of positively and negatively charged ions held together by strong electrostatic forces, whereas covalent compounds generally consist of molecules, which are groups of atoms in which one or more pairs of electrons are shared between bonded atoms.

An ionic compound consists of a large network of ions in which positive and negative charges are balanced. In covalent bond, two electrons (one pair) are shared by two atoms. ... LiCl is an ionic compound because Li is a metal (all elements in the first 2 rows are metals) and chlorine is a non-metal.

It's an ionic compound composed of covalently-bound, polyatomic ions. That is, H and N, and H and O, are covalently bound into and . and ions are combined into an ionic compound, .

Polyatomic ions are covalently bonded compounds that carry an overall charge and can participate in ionic bonds. If one portion of the polyatomic ion is more negatively charged than the other, then it is considered polar.

AlCl3 Although a metal- nonmetal compound, AlCl3 is not ionic (as might be predicted). Single covalent bonds form between alluminium and three chlorine atoms, forming AlCl3 molecules.

Terms in this set (8) What is the main distinction between ionic and covalent bonding? Ionic bonding involves the electrical attraction between large numbers of anions and cations. Covalent bonding involves the sharing of electron pairs between two atoms.

Therefore, they are alkalis. But bases like copper hydroxide Cu(OH)2 ferric hydroxide (Fe(OH)3) aluminium hydroxide (Al(OH)3)do not dissolve in water. They are, therefore, not alkalis.

No: LiOH consists of Li+ and OH-, so it's ionic, but there are three components (Li, O and H), so it's ternary.

Comparison of Ionic and Covalent Bonds Ionic bonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals.

What is the best reason for the difference in properties of LiCl and C6H14O? One compound is covalent, and the other is ionic.

Strong electrostatic forces of attraction exist between the ions. Therefore Na2O and Al2O3 have high melting points. Of the two oxides, Al2O3 has a higher melting point than Na2O. This is because the ionic bond between Al3+ ions and O2- ions is stronger than that between Na+ and O2-.

Some compounds can contain both ionic and covalent bonds such as K2SO4... the sulfate ion is held together with covalent bonds... the potassium ions are ionically bonded to the sulfate ions. Acids are exceptions... they are ionic only when dissolved.
