Yoselin garcia Bond polarity
What does electronegativity of an atom determines?
It determins how strongly it attracts electrons to itself.
A water molecule is polar because its hydrogen and oxygen atoms _____.
Do not share electrons equally
Define Electronegativity
Electronegativity is the ability of an atom to attract electrons when the atoms are in a compound.
True or false all molecules with polar bonds are polar molecules.
FALSE
What is the bond type of a bond with a difference of 1.9?
The bond type of a bond with a difference of 1.9 is classified as polar covalent.
Which type(s) of chemical bonds may be polar bonds?
covalent bonds
In a polar bond, _____ are not shared equally between atoms.
electrons
True or false the covalent bonds in an oxygen molecule (O_2) are polar.
false
The atom with the greater electronegativity acquires a partial ______, while the atom with the lesser electronegativity acquires a _______.
negative charge, partial positive charge.
In a water molecule, oxygen attracts electrons more strongly than the hydrogens do because an oxygen atom contains more _____.
protons
In a non-polar covalent bond, the distribution of electrical charge is balanced between the____ atoms.
two
How do you determine a given bond or covalent ?
you determine a given bond or covalent by calculating the difference in electronegativity between the two atoms involved in the bond.
Define Nonpolar covalent bond
Nonpolar covalent bond is A covalent bond in which the bonding electrons are shared equally between the two atoms.
_______ covalent bonds are bonds between atoms that do not share electrons equally.
Polar
Define Polar covalent bond
Polar covalent bond is A covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal.
A molecule unevenly sharing the electrons in its bonds, making one part slightly positive and the other slightly negative, is referred to as a _____.
Polar molecule
What is the polarity of a bond effected by ?
Polarity of a bond is affected by the electronegativity values of the two atoms involved in that bond.
