CHEMICAL BOND
Basic of CompetenceDescribe possibility of chemical bond occurs by using periodictable
Indicators:Explain the tendency of element to reach its stability by binding with
another elementsDescribe composition of noble gas’ valence electron (duplet and
octet)and lewis stctureExplain the occurance process of ionic and covalent bond and compound
specimenexplore polarity of several compoundand its association electronegativity
through experimentExplain formation process of coordination bond in several simplcompound
specimentsExplain formation process of metallic bond and its association with metal
physical properties

Ionic Bond is a bonding formed as a result of electrons transfer. This leads to
the formation of positive and negative ions which have the noble gas
Metal element ( Li with
configuration 2 1)tends to be stable bygiving 1 electron to form
Li+
Electron that is given by Li metal is
gained by non-metal atom ( O withconfiguration 2 6 ). To reach it’s stablity, O needs 2 electrons to form O2- . Sothat, 1 atom O needs 2 atom Li

The Polarity of Covalent BOnd
The Polarity of covalent bond can be determined based on:a. The difference of electronegativity atom that formed compoundb. Molecule Form of covalend compound
1. Non-polar Covalent CompoundA Covalent bond is non polar when the bond pair is shared equally by bothof nuclei of atoms bonded together(dipole moment=0 or it doesn’t occurs polarisai) with characteristic,molecules shape is simetris.Example
Element Molecule: H2, N2, Cl2, O2 dllCompound Molecule with simetris shape: BeCl2, BeF2, BH3, BCl3, CH4,
CCl4, PCl5, SF6

Polar covalent compound occurs on atoms that have differentelectronegativity is big.If we compare the polarity between H – F and H – Cl, Which one is morepolar?
Absolutely, H –
F is more polar because F has bigger electronegativity morethan Cl
