Al2s3 lewis structure


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.

4.1: Lewis Dot Diagrams (Problems)

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.In all cases, these bonds involve the sharing or transfer of valence shell electrons between atoms.

In this section, we will explore the typical method for depicting valence shell electrons and chemical bonds, namely Lewis symbols and Lewis structures. We use Lewis symbols to describe valence electron configurations of atoms and monatomic ions. A Lewis symbol consists of an elemental symbol surrounded by one dot for each of its valence electrons:.

Figure 1 shows the Lewis symbols for the elements of the third period of the periodic table. Lewis symbols can also be used to illustrate the formation of cations from atoms, as shown here for sodium and calcium:.

Likewise, they can be used to show the formation of anions from atoms, as shown here for chlorine and sulfur:. Figure 2 demonstrates the use of Lewis symbols to show the transfer of electrons during the formation of ionic compounds. We also use Lewis symbols to indicate the formation of covalent bonds, which are shown in Lewis structuresdrawings that describe the bonding in molecules and polyatomic ions. For example, when two chlorine atoms form a chlorine molecule, they mailchimp undo delete block one pair of electrons:.

The Lewis structure indicates that each Cl atom has three pairs of electrons that are not used in bonding called lone pairs and one shared pair of electrons written between the atoms. A dash or line is sometimes used to indicate a shared pair of electrons:. A single shared pair of electrons is called a single bond. Each Cl atom interacts with eight valence electrons: the six in the lone pairs and the two in the single bond.

The other halogen molecules F 2Br 2I 2and At 2 form bonds like those in the chlorine molecule: one single bond between atoms and three lone pairs of electrons per atom. This allows each halogen atom to have a noble gas electron configuration. The tendency of main group atoms to form enough bonds to obtain eight valence electrons is known as the octet rule.

The number of bonds that an atom can form can often be predicted from the number of electrons needed to reach an octet eight valence electrons ; this is especially true of the nonmetals of the second period of the periodic table C, N, O, and F. For example, each atom of a group 14 element has four electrons in its outermost shell and therefore requires four more electrons to reach an octet.

These four electrons can be gained by forming four covalent bonds, as illustrated here for carbon in CCl 4 carbon tetrachloride and silicon in SiH 4 silane. Because hydrogen only needs two electrons to fill its valence shell, it is an exception to the octet rule. The transition elements and inner transition elements also do not follow the octet rule:. Group 15 elements such as nitrogen have five valence electrons in the atomic Lewis symbol: one lone pair and three unpaired electrons.

To obtain an octet, these atoms form three covalent bonds, as in NH 3 ammonia. Oxygen and other atoms in group 16 obtain an octet by forming two covalent bonds:. As previously mentioned, when a pair of atoms shares one pair of electrons, we call this a single bond. However, a pair of atoms may need to share more than one pair of electrons in order to achieve the requisite octet.Aluminum sulfide, also known as dialuminium trisulfide, is an inorganic compound used as raw material in the synthesis of the largely-used hydrogen sulfide.

Formula and structure: Aluminum sulfide chemical formula is Al 2 S 3 and the molar mass is Sometimes this sulfide can be found in its hydrate form, with a variable number of water molecules hydrating it.

Aluminum sulfide has several crystal structures, some of them are the tetragonal, hexagonal and trigonal. Its chemical structure can be written as below, in the common representations used for organic molecules.

Preparation: Aluminum sulfide is prepared by the reaction of the aluminum metal with sulfur powder.

7.3 Lewis Symbols and Structures

They are heated to ignition to form the sulfide though a highly exothermic reaction:. Physical properties: Aluminum sulfide is a gray to black solid. Its density is 2. Aluminum sulfide decomposes in water and is insoluble in acetone. Chemical properties: Aluminum sulfide, similar to other metal sulfides, is slightly soluble in water and largely soluble in acid solutions.

In presence of sodium or potassium bases, it can react to form sodium sulfide, which is an irritant and can cause irritation in skin and eyes. Uses: Aluminum sulfide is used in the preparation of hydrogen sulfide, a compound that is largely used in the chemical industry. Moreover, aluminum sulfide is used in the manufacturing of cathodes that contain lithium-sulfur solid-state batteries.

Along with these applications, aluminum sulfide is also part of the production processes of compounds as ethanethiol. It is poisonous by inhalation. It can cause severe damage in the nervous system and the accumulation in the body can also cause blood damage. Toggle navigation.
