LaoAtoms are joined together to form compounds through chemical bonds. These bonds can be covalent, where atoms share electrons, or ionic, where atoms transfer electrons to achieve stability. The type of bond formed depends on the difference in electronegativity between the atoms involved.

What is a group of atoms that are joined together by chemical bonds?
Molecule
What are two or more atoms joined together calleD?
Two or more atoms joined together are called molecules. These molecules can be composed of the same type of atoms, known as elements, or different types of atoms, forming compounds.
What elements related in compounds?
Elements in compounds are related through chemical bonds, where atoms are joined together to form molecules. These bonds can be covalent (sharing electrons) or ionic (transferring electrons). The properties of compounds are determined by the types of elements present and the arrangement of atoms within the molecule.
What compounds appeared to be joined by covalent bonds?
Compounds formed by nonmetals or a combination of nonmetals and metalloids are typically joined by covalent bonds. These bonds involve the sharing of electrons between atoms to achieve stability. Examples include water (H2O), methane (CH4), and carbon dioxide (CO2).
How are molecular compounds different from an ionic compound?
Molecular compounds consist of covalent bonds formed by sharing electrons between atoms, while ionic compounds involve the transfer of electrons from one atom to another, resulting in the formation of positive and negative ions. Molecular compounds typically have lower melting and boiling points compared to ionic compounds and are often composed of nonmetals. Ionic compounds tend to have higher melting and boiling points, are composed of metals and nonmetals, and form crystalline lattices.
