Cuz they wanna
When atoms lose and gain electrons, an ionic bond will form. When atoms share electrons, a covalent bond will form.
To form a molecule, atoms can share, lose, and gain electrons
Atoms that join by a covalent bond share electrons but do not gain or lose them. In a covalent bond, the electrons are shared between the atoms, creating a stable electron configuration for both atoms involved.
This depends on the electronegativity of atoms.
Ions do not share electrons with other atoms. Ions are formed when atoms gain or lose electrons to achieve a stable electron configuration. Positive ions (cations) lose electrons, while negative ions (anions) gain electrons.
do atoms of a covalent bond lose r share electrons
Some atoms lose electrons, some gain electrons, and some share electrons depending on what elements are involved and what compound is forming.
Atoms share, gain, or lose electrons in order to achieve a stable configuration, usually a full valence shell. This is known as the octet rule. By doing so, atoms can attain lower energy levels and become more stable.
A completely filled shell of electrons has 8 electrons.
Atoms share electrons when they form covalent bonds.
That is correct. Covalent bonds involve the sharing of electrons between atoms rather than the transfer of electrons, as seen in ionic bonds. The atoms involved in a covalent bond share electrons in order to achieve a more stable electron configuration.
A covalent bond forms when atoms share electrons.
