Question

Elements can combine to form molecules, like O₂ or CO₂. Elements combine to form molecules and these elements are joined together by

A.)chemical bonds
B.)nuclear energy
C.)sharing nuclei
D.)attractive forces

Answer 1

Chemical bonds are formed by sharing electrons between atoms. Covalent bonds involve the sharing of electrons, while ionic bonds involve the transfer of electrons.

Step-by-step explanation:

Chemical bonds are the forces of attraction that hold atoms or ions together. When elements combine to form molecules, these bonds are formed by sharing electrons between atoms. Sharing electrons allows atoms to achieve a full outer energy level, which is the most stable arrangement of electrons. There are different types of chemical bonds, including covalent bonds and ionic bonds. In covalent bonds, electrons are shared between atoms, while in ionic bonds, electrons are transferred between atoms.
