An ionic bond occurs when an atom either gains or loses an electron. For example Na+ and Cl- combine to make sodium chloride. The Na+ has lost an electron (it gives one to Cl-) and the Cl- has gained an electron from Na+, that's why they each contain a charge. A covalent bond occurs when two atoms share a pair of electrons for example H2O (water) the O is paired to each H atom through a covalent bond. Hope this helps! :)

When atoms in a covalent bond have a rather high difference in the electronegativities the bond is set to be?
A polar covalent bond.
Is S and O ionic or covalent?
Polar covalent. The difference in electronegtivity is insufficient for an ionic bond
Is the term for a bond between two atoms that differ in electronegativity?
If there is a slight electronegativity difference, the bond is a nonpolar covalent bond. If there is a large electronegativity difference, it is an ionic bond. If the difference is somewhere between, it is a polar covalent bond.
What type of electronegativity difference exists between atoms in a covalent bond?
If the electronegativity difference between two atoms is less than 1.7, then a covalent bond is formed between the two atoms.
What term describes a covalent bond in which electrons are not shared equally?
A covalent bond in which the electrons are not shared equally is a polar covalent bond.

Is SO2 non polar covalent polar covalent or ionic bond?
Polar covalent. The difference in electronegtivity is insufficient for an ionic bond
What type of electronegativity difference exists between atoms in a covalent bond?
If the electronegativity difference between two atoms is less than 1.7, then a covalent bond is formed between the two atoms.
What term describes a covalent bond in which electrons are not shared equally?
A covalent bond in which the electrons are not shared equally is a polar covalent bond.
Is Cl2 a covalent bond or ionic bond?
Covalent. There is no electronegativity difference between two atoms of the same element.
What is the main difference in covalent bonds in diatomic chlorine and diatomic oxygen?
The covalent bond in diatomic oxygen is a double bond and is stronger than the single covalent bond in diatomic chlorine.
What is a covalent bond called in which electrons are shared?
A covalent bond! When the electrons are shared unequally due to a difference in electronegativity between the atoms being bonded it is called a polar covalent bond
We further separate covalent bonds into polar covalent and nonpolar covalent what would have to be the case for a bond to be a nonpolar covalent?
In a nonpolar covalent bond the difference between the electronegativities of the two atoms are not significant.
When is a covalent bond most likely to be polar?
A covalent bond is most likely to be polar when there is a large difference in the electronegativity of the two atoms that form the bond.
Does covalent compounds have a high or low electronegativity?
In comparison with ionic bonds, the difference in electronegativities of elements in a covalent bond have a lower difference in electronegativities. A covalent bond occurs between two nonmetals that have a difference in electronegativities that is 1.7 or less. Usually an ionic bond has a difference in electronegativities that is greater than 1.7, but not always.
