Question

the way of sharing electrons? (equally dinerelle 2. How is an ionic bond or a covalent bond formed? How do you tell the polar or non-polar covalent bond using the way of sharing electro shared, non-polar; unequally shared, polar) 4. How do you tell the ionic bond or covalent bond by the types of elements combined? nonmetal ionic; nonmetal-nonmetal: covalent) In gener 5. How do you know the number of valence electrons does an element have? (Based on the periodic table. e.g. alkali metal, first group, one valence electron, Oxygen: VI group, six valence electrons, etc.) e hnhunn hun nonmetals? (hased on the number of

Date: Page 2 formation of lonic Bond formed by By transfer of electron from metal to Non metal Ex. . Na nat te {nat - cation} • cite ci {er - Anion} Nataci C G Nat cí z No 2.807 2.0, 218,0 Na Na 2,817 2.8 ,28,2 formation of Covalent bond Covalent bond formed by the sharing of Electron between two atom Example – formation of H₂ HXH two elechon shared between two hydrogen atom to form. Single Covalent bond (3) Non polar Covalent bond formed between the atom whose Electronegativity same or approxmate Same that's why shared Electron alway. locate between two bonded atom H : H But in polar Covalent bend formed between two atom whose I Electronegativity different, so some time Shared Election Slightly move toward higher Electonegative

Non metal have two tendency. Grein of e- OR sharing of e-

thank you very much

Date Page: 5 Valence Election means - Total Number of Duter most shell Electron in Periodic table Based one Atomic Number and Atomic Number indicate the Number of valence Electron Example magnesium → Ind Group See atomic Number = 12 - 2,8, (2 valence election of my Now valence élection = Group. Number 1 another Example N 2,5 5' valence electron for Nitrogen atom so Group Number of Nitrogen - I = Group. Number Conclusion - Valence Election Thank you very much
