Answer 1

The correct answer is H2O.

Key Points

H2O, commonly known as water, consists of two hydrogen atoms and one oxygen atom.
The bonds in H2O are covalent bonds, where atoms share electrons to achieve a full outer shell.
Each hydrogen atom shares one electron with the oxygen atom, resulting in two covalent bonds.
Unlike ionic bonds, which involve the transfer of electrons, covalent bonds involve the sharing of electrons between atoms.

Additional Information

Ionic Bonds
- Ionic bonds are formed when one atom transfers electrons to another atom, leading to the formation of ions.
- Common in compounds formed between metals and non-metals, such as NaCl (table salt).
- In ionic bonds, the resulting ions are held together by electrostatic forces.
Covalent Bonds
- Covalent bonds involve the sharing of electron pairs between atoms.
- Common in organic molecules and many non-metal compounds, such as CO2 (carbon dioxide).
- Covalent bonds can be single, double, or triple, depending on the number of shared electron pairs.
Examples of Molecules with Ionic Bonds
- LiCl (Lithium Chloride): Formed by the transfer of an electron from lithium to chlorine.
- MgO (Magnesium Oxide): Formed by the transfer of two electrons from magnesium to oxygen.
Examples of Molecules with Covalent Bonds
- CH4 (Methane): Formed by the sharing of electrons between one carbon and four hydrogen atoms.
- O2 (Oxygen): Consists of two oxygen atoms sharing two pairs of electrons (double bond).
