Ionic v Covalent bonds [ENDORSED]

[Caitlin Beale 3E]

How does one know if a bond will be ionic or covalent?

[Ryan Burchell 3D]

It has to do with the difference in electronegativities of the two atoms. If the electronegativity difference is less than .5 then it is nonpolar covalent, in-between .5 and 1.6 are polar covalent bonds and anything greater than 1.6 should be an ionic bond.

In covalent bonds, electrons are shared between atoms. In ionic bonds, an electron is donated from one atom to another.

[Eszter Kovacs 1A]

Ionic bonds are usually formed between non-metals and metals, mainly alkaline and alkaline-earth metals. Covalent compounds are usually made up of non-metals

[Lucy Farnham 1G]

Covalent bonds occur between nonmetals and ionic bonds occur between a metal and nonmetal in most cases. We can look at the periodic table to see what kind of elements they are and deduce what kind of bond occurs.

[Santiago Chang 2K]

You can determine if a bond is covalent or ionic based on the difference in electronegativities. A difference of <.5 is typically a nonpolar covalent bond. A difference of .5 to 1.6 is usually a polar covalent bond. A difference of >1.6 is normally an ionic bond. Hope this helps!

if the element is transferring electrons (metals and nonmetals), then it is an ionic compound, but if the electrons are being shared (usually nonmetals), then they are covalent bonds

[Reece Fong 2k]

General rule of thumb is that metals and nonmetals will form an ionic bond while nonmetals will form covalent bonds and metals form metallic bonds. This is because nonmetals are too electronegative to completely give up their electrons, so they share opposed to metals that are looking to give electrons away to form an octet.

[Cindy Vo 3E]

Typically, an ionic bond will occur between a metal and nonmetal, and a covalent bond will occur between two nonmetals.

[SuryaDham 3E]

covalent bonds are usually between non metals on the right side of the table and share electrons
ionic bonds are usually between nonmetals and metals and one element will completely take electrons from the other.

Ionic bonds usually form between a metal and nonmetal while covalent bonds usually form between two nonmetals. The type of bond can also be determined by the difference in electronegativity. If the difference is very large, then it is most likely an ionic bond. If the difference is slight, it could be either a polar covalent or nonpolar covalent bond.

[HannahArabi14a]

The difference between ionic and covalent bonds are the following:

Ionic Bonds: atoms donates electrons to another atom. Ionic bonds are typically formed between a non metal and a metal.

Covalent Bonds: electrons will be shared between atoms. Covalent bonds atoms are typically formed between two non metal elements.

Ionic bonds typically occur between a metal (ex: Na) and a nonmetal (ex: Cl), because they have a large difference in ionization energies. It's easier to pull an electron off one (metal, with the lower ionization energy) and give it to the other (nonmetal, with a higher electron affinity). Covalent bonds, however, are between two atoms that are usually in the p-block and more similar to each other (ex: two carbon atoms). Because these two atoms are more similar to each other, you can't just take one electron and fully give it to the other. Both atoms are pulling on the electron with almost equal or equal strength. As a compromise, the atoms will share the electron between themselves.

Ionic bonds usually happen between metals and nonmetals while covalent bonds usually happen between two nonmetals. There can be exceptions to this rule though.

[Elizabeth Kim 2K]

Hi! An ionic bond forms between a nonmetal and a metal when one donates electrons to the other, while a covalent bond forms when electrons are shared between two nonmetals. Hope this helps!

[Fiona H 2E]

Compounds containing two elements can be either ionic or covalent.As a general rule, if a compound is made from a metal and a non-metal, its bonding is ionic. And if a compound is made from two non-metals, bonding is covalent.

[Isabelle Kim 3E]

Ionic bonds are formed by donating electrons between two atoms. For example, a very common ionic compound is table salt (NaCl). In this compound, there is an anion AND cation. The anion is the Cl and cation is the Na. The cation donates a single electron to the anion to create the ionic bond.
Whereas, covalent bonds are formed by sharing electrons. There is no act of giving up or receiving electrons like in the ionic bonds. For example, CO2 is a covalent compound.

Another thing to note is the different properties of these two chemical bonds. The concept of electronegativity is very important here since it explains the overall properties of covalent bonds. Covalent bonds are only formed between NON-METALLIC elements, so then there’d be an equal electronegativity measured within the covalent compound elements. As for the ionic compound elements, the electronegativity would not be as similar.

[Jahnavi Srinivas 2H]

Ionic bonds form between a metal and a nonmetal when they exchange electrons. On the other hand, covalent bonds form between a non-metal and another non-metal. In this case, electrons are shared between the atoms.

[Mahima Manoj 1F]

Ionic bonds exchange electrons and are usually between nonmetal and metal while covalent bonds are shared electrons that usually form between two nonmetals

[emmakvarnell]

A bond is ionic when a cation gives up its electrons to an anion. A bond is covalent when two non-metals share electrons. Mathematically, once we're introduced to numerical bond values through electro negativities, we'll get specific values to look at to tell which ones are ionic vs. covalent.

[Jessica Sun 2I]

While covalent bonds have shared electrons between two atoms, ionic bonds have one atom give electrons to another to complete an orbital. This is due to the difference in electronegativities. Ionic bonds are between an atom with very high electronegativity and an atom with very low electronegativity. Covalent bonds are between atoms with two atoms with similar electronegativities.

[Madison Nguyen 3L]

Metals will form an ionic bond, whereas nonmetals will form covalent bonds due high electronegativity; nonmetals do not want give away many electrons to become stable, so they share electrons to compensate (aka covalent bonds). Metals have low electronegativity, however, and want to give electrons away to become stable -- hence, forming an ionic bond and becoming either a cation or anion.

[Amy Jordan 2A]

Hi! You can determine if a bond is ionic or covalent by looking at the difference in electronegativity between the atoms or elements. If the electronegativity difference is greater than 2, it is an ionic bond. If the electronegativity difference is less than 1.5 it is a covalent bond. Also, ionic bonds are usually between a nonmetal and a metal, while covalent bonds are usually between two nonmetals. Hope this helps!
