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.
