what is a covalent bond
where tow atoms share a a pair of electrons, between a non matal and non matal, to gain a full puter shell and becpme a noble gas
1 of 10
what is electronegativity
is the measure of how strong an atom is able to attract a lone pair of electrins
2 of 10
why does chlorine attract more electrons than hydrogen
chloribne has a higher elecrtonnegativity and therefore has delta- as it attrcats more -ve electrons, hydrioge has a low electronagativity and is delta+ as it has less electrons
3 of 10
what is a polar covanet bond
covalent bond formed from atoms woth different electronegativity so electrons will be shared unequally
4 of 10
what is a non poar covalent bond
covalent bond beyween two atoms with the same electronegativity so elctrons shared equally
5 of 10
what is dative covalent
covalent bond when atoms are shared are donated elctron to another atom
6 of 10
what does the arrow show in dative covalnt bonds
the direction of the electrons
7 of 10
what is an ionic compoaund
a bond formed btween atoms with different elctoronegtobity and electrons are transgered completely resulting in pakcaged ionic lattice
8 of 10
what is the elctrostaic attrcation
electrostaiv attraction between opposite charged atoms
9 of 10
what is electrostaic repulsion
electrostatic repulsion is btween atoms of same charge
