Chemical Bond: The attraction between two or more atoms to formulate a chemical substance, this bond is due to the electrostatic force of attraction between electrons of opposite charges, or this bond is due to a dipole attraction is called a chemical bond.
Types of Bonds: The force of attraction as well as chemical properties in atoms or molecules of elements or compounds contrives three different types of chemical bonds.
1. Ionic Bonding: The bond which generates two oppositely charged ions and the complete transfer of valence electrons is an ionic bond. Metals by losing their outer most electrons they can achieve a noble gas configuration and satisfy their octet rule , similar happens to the non-metals but …show more content…

For e.g. water, ozone. • When there is same sharing of electrons between two atoms it forms non polar covalent bond, it usually happens when the atoms have same or similar electron affinity.
• Atoms with higher electro negativity will pull the low electron negativity atom, but this will not happen in a diatomic molecule because their electro negativities will cancel each other.
• For example, hydrogen molecule shares non polar covalent bond.

3. Co-ordinate covalent Bond: A co ordinate bond is when electrons are bonded of the same atoms. They are also called dipolar or dative covalent bond. The term for its structure can be used as ligands, in which each of them donates a pair of electron to the centre of metal. For example, in hexaaminechloride, BF3, Nh4Cl etc.
Metallic Bonding: Metals are conductor of electricity, with low ionization energy and also low electron negativity; they are cations they give up electrons easily. They have high melting and boiling points, even Sodium can melt at a high temperature. A strong metallic bond is based on the delocalization of electrons which causes a nuclear charge effective for electron bonding. Bond

    Metals contain a sea of electrons (which are negatively charged) and which flow throughout the metal. This is what allows electric current to flow so well in all metals. An electrode is a component of an electric circuit that connects the wiring of the circuit to a gas or electrolyte. A compound that conducts in a solution is called an electrolyte. The electrically positive electrode is called the anode and the negative electrode the cathode.

  • Intermolecular Forces Essay

    1063 Words  | 3 Pages

    Intermolecular forces are the forces that hold molecules together. These forces responsible for many of the properties of molecules such as boiling point, freezing point, reactivity, etc. There are four types of intermolecular forces. These forces include the ionic bond which is the transfer of electrons between two ions. The ionic bond happens only when one atom is much more electronegative than the other. This bond interaction is by far the strongest of the four. An example of the ionic interaction is NaCl or table salt – the Na atom is the positively charged ion while the Cl is the negatively charged ion. The second intermolecular force is the dipole-dipole force. It is considered a covalent bond but the bond is not completely covalent. In this particular bond, the electron sharing is not completely even thus placing the bond as a polar covalent bond. In this type of bond, the electron density shifts

  • The Importance of Sodium

    606 Words  | 2 Pages

    Metals form giant structures in which electrons can move freely in the outer shell. The metallic bonding is the power of attraction between these free electrons and metal ions. Sodium is an extremely malleable metal with a silver colour which can be cut with a knife at room temperature. The boiling and melting points are considerably high at 883C for boiling and 97.72C for the melting point. Sodium is also a very good conductor of electricity. Sodium is a metal therefore it doesn’t form covalent bonds, only non-metals can for covalent. The “sea of electrons” is electrons that can move without restrictions within the molecular orbitals, so each electron detaches from its “parent” atom. The atoms are most ...

    Every chemical element or compound have specific properties that make them different than the other. However, these properties help us to understand every element or compound in which they can be used and how we can deal with them. These properties can be chemical properties which are defined as "that property must lead to a change in the substances ' chemical structure", such as heat of combustion and flammability ("Physical and Chemical…"). Also, these properties can be physical properties which are defined as the properties "that can be measured or observed without changing the chemical nature of the substance", such as mass, volume, boiling and freezing points ("Physical and Chemical…"). These two properties are related to each other. For

    The bond with each other in an interesting way that causes the boiling points of the molecules produced to be higher. Due to the electronegativity of the molecules being closer than that of hydrogen the molecules it causes the polar interaction between the molecules to be weaker. Making it so that, the forces in dipole-dipole interactions are weaker than in hydrogen bonding. This shows that the attractions between molecules are getting stronger as you go down the group which causes more energy needed to break them. The stronger the dipole-dipole forces are the more energy is needed to break them where as the weaker the dipole-dipole forces are the less energy is needed to break them.

  • The Properties of Tradition Metals

    894 Words  | 2 Pages

    Transition metals are a group of metals that are considered dense and have high melting and boiling points. They are located between the alkaline earth metals group and the boron group. The transition metals are characterized by the number of inner energy levels that are occupied by the atoms. They are then separated into 2 groups: d-type transition metals and f-type transition metals. D-type transition metals are mostly consisted of important metals (commercially) and the rare and unimportant metals. They are ranged from very reactive to noble. The metals in this group all form a variety of different alloys. The f-type transition metals consists of lanthanides (rare earth metals) and actinides which is from thorium to lawrencium. These metals are very reactive. Only a few of these elements are common but several of the f-type elements are useful. For example, cerium and thorium, which are found in alloys, uranium and plutonium in nuclear reactors.

    Crystals can also be grouped as covalent, metallic, ionic and molecular crystals based on the physical and chemical properties. Covalent crystals have true bonds between all atoms in them. In metallic crystals, the individual metal atoms sit on lattice sites leaving the outer electrons free to float around the lattices. The atoms of ionic crystals are held together by electrostatic forces. A molecular crystal is held jointly by non-covalent interactions such as van der Waals forces or hydrogen bonding. Different crystals have different shapes and sizes which may be due to two factors: Internal symmetry

    From these properties of bonds we will see that there are two fundamental types of bonds--covalent and ionic. Covalent bonding represents a situation of about equal sharing of the electrons between nuclei in the bond. Covalent bonds are formed between atoms of approximately equal electronegativity. Because each atom has near equal pull for the electrons in the bond, the electrons are not completely transferred from one atom to another. When the difference in electronegativity between the two atoms in a bond is large, the more electronegative atom can strip an electron off of the less electronegative one to form a negatively charged anion and a positively charged cation. The two ions are held together in an ionic bond because the oppositely charged ions attract each other as described by Coulomb's Law.
