Download all of the worksheets from this page as a single bundle. The bundle includes the fully scaffolded, partially scaffolded and unscaffolded bonding worksheets plus the separate scaffolded worksheets on covalent, ionic and metallic bonding as both MS Word and pdf.
The Bonding worksheets cover covalent, ionic and metallic bonding, available with three levels of support: scaffolded, partially scaffolded and unscaffolded. You will find model answers to all levels of these worksheets in the teacher guidance.
An additional scaffolded worksheet focussed on covalent bonding is available as MS Word or pdf. Learners select words from a word list to complete sentences. Use this worksheet at the end of a lesson on covalent bonding or to support learners who struggle with covalent bonding. These learners could then be encouraged to attempt the partially scaffolded bonding worksheet to reinforce their understanding. You will find model answers in the teacher guidance which is also available as MS Word or pdf.

The attractive force which holds together the atoms or group of atoms in a chemical species is known as a chemical bond. The definition of the chemical bond as a shared electron pair could be extended to describe the dative bond and the elaboration of Lewis acid/base interactions.
To make you understand how Ionic, covalent and metallic bonds are different from each other, here are some of the major differences between Ionic, covalent and metallic bonds:
Magnesium, sodium, and aluminium are examples of metallic bonds. Metallic bonding provides malleability, ductility, thermal and electrical conductivity, opacity, and lustre, which are all characteristics of metals.
Ionic bonds are electrostatic interactions between atoms that are held together by their attraction to each other. In ionic bonds, one atom gives up an electron to another atom, which creates charged ions that are attracted to each other. Ionic bonds are usually between a metal and a nonmetal.
In order to understand the difference between ionic, covalent, and metallic bonds, it is important to first understand on what basis these can be differentiated. Therefore they can be differentiated on the basis of occurrence, conductivity, binding energy, bond, state of presence, melting point, boiling point, ductility, and malleability.
Ionic bonds do not conduct electricity in the solid-state but they do in the liquid and molten state. Covalent bonds do not conduct electricity in any state. Metallic bonds are good electrical conductors in all states.
Ionic bonds are present in the solid, liquid, and gaseous states. Covalent bonds are present in all three states but are strongest in the solid-state. Metallic bonds are present in all three states but are strongest in the solid-state.
From the above discussion, it can be concluded that ionic, covalent, and metallic bonds differ from each other on the basis of occurrence, conductivity, binding energy, bond, state of presence, melting point, boiling point, ductility, and malleability.
In short, ionic bonds are formed when a metal and a nonmetal come together. Ions are created as the electron from the metal atom transfers to the nonmetal atom. Covalent bonds form when two atoms share electrons in order to fill their outer shells. Metallic bonding is unique in that it occurs when atoms lose their outermost electrons completely. These free-floating electrons then bond with other metal atoms, creating a metallic solid. So what difference does all of this make for students? The key takeaway is that covalent and metallic bonding produce different types of materials with distinct properties. Understanding these differences can help you predict how substances will behave, which can be enormously helpful when trying to solve problems in chemistry or physics labs.
Answer: An ionic bond is a type of chemical bond that involves electrostatic attraction. These attractions are ions that are oppositely charged, or between two atoms with strongly opposing charges. Ionic bonds form when atoms lose or gain electrons, resulting in a difference in their electrical charges. These atoms then attract each other, due to their opposite charges.
Answer: A covalent bond is the chemical bond type that involves the sharing of electrons between two atoms. Covalent bonds form when atoms share electrons in order to fill their outermost energy level or valence shell. This type of bond results in the atoms being held together by their shared electrons.
Answer: A metallic bond is a type of chemical bond that involves the sharing of electrons between metal atoms. Metallic bonds form when the metal atoms lose their outermost electrons. These atoms then share their electron clouds, which results in the formation of a metallic bond.
Answer: The difference between ionic, covalent, and metallic bonds lies in the way that the atoms are held together. Ionic bonds are held together by the electrostatic attraction between contrarily charged ions. Covalent bonds are held together by the sharing of electrons between the atoms. Metallic bonds are held together by the sharing of electrons between metal atoms.
Answer: An example of an ionic bond would be the electrostatic attraction between a positively charged sodium atom and a negatively charged chlorine atom. This would result in the formation of sodium chloride (table salt).
