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! :)

What type of electronegativity difference exists between atoms in a covalent bond?
In a covalent bond, atoms with a small electronegativity difference share electrons almost equally, creating a nonpolar covalent bond. When there is a larger electronegativity difference, one atom pulls the shared electrons more strongly, resulting in a polar covalent bond.
What is the largest possible electronegativity difference for a bond to be covalent?
The largest possible electronegativity difference for a bond to be considered covalent is around 1.7. When the electronegativity difference between two atoms in a bond exceeds this value, the bond is usually considered ionic rather than covalent.
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
Does HF have a polar covalent bond?
yes it is a polar covalent bond. the difference of electronegativities of H and F is 1.9 , it should be an ionic bond but the ratio of atomic sizes of both the atoms is responsible for polar covalent bond.
When atoms in a covalent bond have a rather high difference in the electronegativities the bond is set to be?
When atoms in a covalent bond have a rather high difference in electronegativities, the bond is considered polar covalent. This means that one atom will have a partial negative charge, while the other will have a partial positive charge due to the unequal sharing of electrons.

Is SO2 non polar covalent polar covalent or ionic bond?
Polar covalent. The difference in electronegtivity is insufficient for an ionic bond

A covalent bond formed between two elements that have an electronegativity difference of 1.6 would be?
a very polar bond.

Which type of bond is formed when electronegativity difference is zero?
A nonpolar covalent bond is formed when the electronegativity difference between atoms is zero. In a nonpolar covalent bond, the atoms share electrons equally because they have the same electronegativity.
What is the increasing ordor of electronegativity in ionic bond and polar covalent bond and non polar covalent bond?
The increasing order of electronegativity in bonds is lowest for nonpolar covalent bonds, followed by polar covalent bonds, and highest for ionic bonds. In nonpolar covalent bonds, the electronegativity difference between atoms is minimal, whereas in polar covalent bonds, there is a moderate electronegativity difference leading to partial charges. Ionic bonds have the highest electronegativity difference, resulting in complete transfer of electrons.
What is difference between covalent and co- ordinate covalent bond?
In a covalent bond, two atoms share a pair of electrons, whereas in a coordinate covalent bond, one atom provides both electrons in the shared pair. Coordinate covalent bonds are a type of covalent bond where one atom donates both electrons to the bond.
What is the main difference in covalent bonds in diatomic chlorine and diatomic oxygen?
The main difference is in the number of electrons shared in the bond. Diatomic chlorine (Cl2) forms a single covalent bond, sharing 1 pair of electrons, while diatomic oxygen (O2) forms a double covalent bond, sharing 2 pairs of electrons. This difference affects the bond strength and characteristics of the molecules.
Is S and O ionic or covalent?
Polar covalent. The difference in electronegtivity is insufficient for an ionic bond
