I WONDER - What Is A Chemical Bond?

Atoms bond to form molecules in various ways. Covalent bonds involve sharing electrons, common among non-metals like in water (H2O). Ionic bonds involve electron transfer, typically between metals and non-metals, as seen in table salt (NaCl). Metallic bonds feature free-moving electrons among metals, creating a 'sea of electrons'.

What type of bond involves atoms sharing electrons, similar to sharing toys?

• Hydrogen bond

• Metallic bond

• Covalent bond

• Ionic bond

In which type of bond does one atom donate an electron to another?

• Ionic bond

• Van der Waals bond

• Covalent bond

• Metallic bond

Which of the following is an example of an ionic compound?

• Water (H2O)

• Table salt (NaCl)

• Carbon dioxide (CO2)

• Methane (CH4)

What is the unique feature of metallic bonds?

• Electrons are fixed in place

• Electrons float freely like a sea

• Electrons are shared between atoms

• Electrons are transferred from one atom to another

Which type of bond is characterized by a 'sea of electrons'?

• Hydrogen bond

• Ionic bond

• Covalent bond

• Metallic bond
