3.1 types of chemical bonds Flashcards
what are chemical bonds?
a strong force of attraction that holds atoms together
what are covalent bonds?
bonds that share electron pairs between atoms
what are polar bonds?
unequal sharing of electrons between atoms
what are fractional charges?
an object that carries only a portion of the electrical charges
what are non polar bonds?
equal sharing of electrons between atoms
what are ionic bonds?
ionic bonding is a form of chemical connection where the atom loses valence electrons and gains them back from another atom.
what is coulomb’s law?
states that like charges repel and opposite charges attract, with a force proportional to the product of the charges and inversely proportional to the square of the distance between them.
what is a structural formula?
the arrangement of atoms in the molecule of a compound.
what is the space-filling model?
a three dimensional model used to show how much space an atom occupies.
what is the ball and stick model?
three dimensional where atoms are represented as spheres of different colors, and sticks between spheres.
what is bond length?
the distance between the centers of two covalently bonded atoms
