Question

bonds? yes
when hydrogen atoms covalently bonded to nitrogen (n), oxygen (o), or
fluorine (f) in the form of covalent compounds such as ammonia (nh3), water
(h2o) and hydrogen fluoride gas (hf), the hydrogen atoms do not pull as
strongly on the shared electrons as the nitrogen (n), oxygen (o), or fluorine (f)
atoms.

the molecule being slightly positive
nonpolar molecules
and the other slightly negative;
polar molecules
example: water
have electrons distributed evenly,
choose
with no distinct positive or
negative poles.

Explanation:

Polar molecules have an uneven distribution of electrons, leading to partial positive and negative charges (e.g., water). Non - polar molecules have even electron distribution with no distinct poles.

Answer:

First blank: Polar molecules
Second blank: Nonpolar molecules
