Can anyone tell me if my answers are right or if any of these are nonpolar covalent. All I have in the question is the formula given above and of course the periodic table.
Look at the electronegativity difference for each molecule. You will need an electronegativity chart to do so. If the difference is less than 0. If it is between 0.
Anything above 2. For example, the eletronegativity of Na is 0. You can tell if a substance is ionic,covalent by looking at each of the individual atoms which make up the compound. Covalent substance is made up of ALL non-metal substances, and the atoms have to share electrons to bond and become stable.
As for the non-polar or polar bit, there is no way to tell from the chemical formula, although you can try out the substance by trying to dissolove it in water, if it does dissolve, its a polar substance and if it doesnt, its not.

We often take a lot of things for granted. We just assume that we will get electric power when we connect a plug to an electrical outlet. The wire that comprises that outlet is almost always copper, a material that conducts electricity well. The unique properties of the solid copper allow electrons to flow freely through the wire and into whatever device we connect it to.
Then we can enjoy music, television, work on the computer, or whatever other activity we want to undertake. Crystalline substances can be described by the types of particles in them and the types of chemical bonding that takes place between the particles.
There are four types of crystals: 1 ionic2 metallic3 covalent network, and 4 molecular. Properties and several examples of each type are listed in the following table and are described in the table below. Ionic crystals -- The ionic crystal structure consists of alternating positively-charged cations and negatively-charged anions see figure below. The ions may either be monatomic or polyatomic. Generally, ionic crystals form from a combination of Group 1 or 2 metals and Group 16 or 17 nonmetals or nonmetallic polyatomic ions.
Ionic crystals are hard and brittle and have high melting points. Ionic compounds do not conduct electricity as solids, but do conduct when molten or in aqueous solution. Metallic crystal -- Metallic crystals consist of metal cations surrounded by a "sea" of mobile valence electrons see figure below.
These electrons, also referred to as delocalized electrons, do not belong to any one atom, but are capable of moving through the entire crystal. As a result, metals are good conductors of electricity. As seen in the table above, the melting points of metallic crystals span a wide range.
Covalent network crystals -- A covalent network crystal consists of atoms at the lattice points of the crystal, with each atom being covalently bonded to its nearest neighbor atoms see figure below. The covalently bonded network is three-dimensional and contains a very large number of atoms. Network solids include diamond, quartz, many metalloids, and oxides of transition metals and metalloids. Network solids are hard and brittle, with extremely high melting and boiling points.
Being composed of atoms rather than ions, they do not conduct electricity in any state. Molecular crystals -- Molecular crystals typically consist of molecules at the lattice points of the crystal, held together by relatively weak intermolecular forces see figure below.Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another.
This exchange results in a more stable, noble gas electronic configuration for both atoms involved. An ionic bond is based on attractive electrostatic forces between two ions of opposite charge.
Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Another atom, typically a non-metal, is able to acquire the electron s to become a negative ion, or anion.
One example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom. In this reaction, the sodium atom loses its single valence electron to the fluorine atom, which has just enough space to accept it. The ions produced are oppositely charged and are attracted to one another due to electrostatic forces. At the macroscopic scale, ionic compounds form lattices, are crystalline solids under normal conditions, and have high melting points.
Most of these solids are soluble in H 2 O and conduct electricity when dissolved. The ability to conduct electricity in solution is why these substances are called electrolytes.
Table salt, NaCl, is a good example of this type of compound. Ionic bonds differ from covalent bonds. Both types result in the stable electronic states associated with the noble gases. However, in covalent bonds, the electrons are shared between the two atoms. All ionic bonds have some covalent character, but the larger the difference in electronegativity between the two atoms, the greater the ionic character of the interaction. Ionic Bonding — YouTube : In this video, Paul Andersen explains how ionic solids form when cations and anions are attracted.
Lattice energy is an estimate of the bond strength in ionic compounds. It is defined as the heat of formation for ions of opposite charge in the gas phase to combine into an ionic solid. Alternatively, lattice energy can be thought of as the energy required to separate a mole of an ionic solid into the gaseous form of its ions that is, the reverse of the reaction shown above. Lattice energy cannot be determined experimentally due to the difficulty in isolating gaseous ions.
The energy value can be estimated using the Born-Haber cycle, or it can be calculated theoretically with an electrostatic examination of the crystal structure. This model emphasizes two main factors that contribute to the lattice energy of an ionic solid: the charge on the ions, and the radius, or size, of the ions.
The effect of those factors is:. Lattice energies are also important in predicting the solubility of ionic solids in H 2 O. Ionic compounds with smaller lattice energies tend to be more soluble in H 2 O.
Lattice Energies — Chemistry Tutorial : This tutorial covers lattice energy and how to compare the relative lattice energies of different ionic compounds. Ionic formulas must satisfy the noble gas configurations for the constituent ions and the product compound must be electrically neutral.
An ionic bond is formed through the transfer of one or more valence electrons, typically from a metal to a non-metal, which produces a cation and an anion that are bound together by an attractive electrostatic force.
On a macroscopic scale, ionic compounds, such as sodium chloride NaClform a crystalline lattice and are solids at normal temperatures and pressures. The charge on the cations and anions is determined by the number of electrons required to achieve stable noble gas electronic configurations.
The ionic composition is then defined by the requirement that the resulting compound be electrically neutral overall. For example, to combine magnesium Mg and bromine Br to get an ionic compound, we first note the electronic configurations of these atoms valence level in indicated in italics :.
Are the bonds in each of the following substances ionic, nonpolar covalent, or polar covalent?
In order to achieve noble gas configurations, the magnesium atom needs to lose its two valence electrons, while the bromine atom, which has 7 valence electrons, requires one additional electron to fill its outer shell. Therefore, for the resulting compound to be neutral, two bromine anions must combine with one magnesium cation to form magnesium bromide MgBr 2.
In addition, though any ratio of 2 bromine atoms to 1 magnesium atom will satisfy the two requirements above, the formula for ionic compounds is typically presented as the empirical formula, or the simplest whole-number ratio of atoms with positive integers. Note that the cation always precedes the anion both in written form and in formulas. In the written form, while the cation name is generally the same as the element, the suffix of single-atom anions is changed to — ide, as in the case of sodium chloride.
