Single bonds are formed by sharing one pair of electrons. The chemical bond formed as a result of the sharing of electrons between the combining atoms is called a covalent bond. What happens during the formation of fluorine molecule electron transfer or electron sharing? The manner in which the two fluorine atoms in a fluorine molecule undergo chemical bonding is illustrated in fig. How can the two fluorine atoms attain an octet arrangement? Is there a possibility of transferring electrons from one fluorine atom to another fluorine atom? How many electrons are required for one fluorine atom to attain the octet? The Bohr atom model of fluorine is given in figure. Let us examine the formation of these molecules. Ĭompounds formed by ionic bonding are called ionic compound.įluorine, Chlorine oxygen Nitrogen etc. How the ionic bond formation of sodium oxide is represented?ĭraw the electron dot diagram of following compounds. To attain stability magnesium donates 2 electrons to become magnesium ion (Mg 2 +) and – oxygen become ion. Ionic bond is a chemical bond formed by electron transfer in an ionic bond, the ions are held together by the electrostatic force of attraction between the oppositely charged ions.Įxplain the formation of magnesium oxide from magnesium and oxygen?Īnalyze the electron dot diagram and complete the table. This attractive force is called Ionic Bond. The oppositely charged ions thus formed are held together by electrostatic force of attraction. Through this sodium and chlorine atoms complete an octet in their outermost shell to attain stability. The diagram represents only electrons in the outermost shell because they are the only electrons participating- in chemical bonding.Ĭomplete Table 2.3 by examining the arrangement of electrons before and after the chemical reaction during the formation of sodium chloride.Ī) Which atom donates electron? How many electrons?ī) Which atom accepts electron? How many electrons?Įlectron transfer during the formation of sodium chloride can be written in the form of an equationĭuring the formation of sodium chloride sodium atom donates electron and gets converted to sodium ion (Na +) chlorine accepts an electron to form chloride ion (Cl – ).

Sodium donates one electron to chlorine to become sodium ion and chlorine become chloride ion Īnalyze the electron transfer in each atom during the formation of sodium chloride.ĭraw the electron dot diagram of the transference of electron of sodium atom and chlorine atom. How do chlorine and sodium attain stability? How many electrons are there in outermost shell of chlorine? How many electrons are there in the outermost shell of sodium atom?

In the formation of sodium chloride which atoms are combing. The attractive force that holds the atoms together in the formation of a molecule is called chemical bonding. (ii) How are atoms in these compounds held together? Magnesium chloride, Sodium oxide, Sodium chloride. (i) You are familiar with the compounds of these elements. Is the number of electrons in the outermost shell of these elements the same as that of the elements in Table (2.1). The electronic configuration of some elements are given below.

Hence two-electron pattern system of Helium also stable. The maximum number of electrons in the first shell is 2. The arrangement of eight electrons in the outermost shell of atom is called octet electron configuration. What peculiarity do you see in the electronic configuration of noble elements except Helium? Except Helium all other elements have 8 electrons in the outermost shell, hence shall be considered to be chemically stable.
