2.3 chemical bonds Flashcards
what happens with electrons in polar covalent bonds
shared between 2 nonmetals when electrons are shared
what happens with electrons in nonpolar covalent bonds
shared equally, C-H, S-H
what happens with electrons in polar bonds
shared unequally, except C-h, S-H
properties of ionic bonds
between a metal and nonmetal, being transferred, really high and really low, more than 1.7
properties of covalent bonds
occur between 2 nonmetals when electrons are shared
different between polar and nonpolar covalent bonds
polar is unequal and large difference in polarity and nonpolar is equal with small or no difference in polarity
When given two atoms what type of bonds will form between them and why
either ionic or covalent depending on if they are two nonmetals or one nonmetal and metal
how does electronegativity determine what type of bond two atoms will form?
electrongativity determines the bond based on the amount it has; polar covlanet=0.4-1.7, mostly convalent=less than 0.4, mostly ionic=greater than 1.7
