Be and Cl form an ionic bond (BeCl2), and it is polar.
For a molecule of oxygen, O2, the bond is nonpolar covalent.
Definitely nonpolar.A molecule becomes polar if one of the atoms pulls electrons more strongly than another. But O2 is completely symmetrical--it's just two O atoms that are exactly alike. One can't pull more strongly than another, so it must be nonpolar.
Chlorofluorocarbons release free Chlorine into the atmosphere where the chlorine reacts with ozone to break it down into oxygen. 1) CF2Cl2→CF2Cl+Cl (by uv light) 2) Cl+O3→ClO+O2 3) ClO+O→Cl+O2 So the Cl molecule is recycled some 100,000 times before another reaction removes the free Cl- from the atmosphere.

Generally anions. (e.g. Cl-, F-, O2-, N3-)
Be and Cl form an ionic bond (BeCl2), and it is polar.
Nonpolar covlalent bond
i have it as nonpolar cuz the Cl are on all sides and they're da same (like PH3)
Iodine is not soluble in water because iodine is nonpolar and water is polar. According to the "Like dissolve like" expression, nonpolar substances are soluble with nonpolar substances and polar substances are soluble with polar substances, but nonpolar substances are not soluble with polar substances.
yes O2 they share equally
For a molecule of oxygen, O2, the bond is nonpolar covalent.
ClO2 → Cl + O2
O2

nonpolar covalent bonds
Polar because of the delta charges on the Cl and F atoms The carbon atom is delta positive, and the Cl and F delta charges are negative.
