Because they don't have a full outer shell of electrons, 2,8,8,18
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
they share electrons
This depends on the electronegativity of atoms.
Atoms in the oxygen family can gain or share two electrons in order to achieve an octet of electrons.
Yes.
Some atoms lose electrons, some gain electrons, and some share electrons depending on what elements are involved and what compound is forming.
Atoms gain, share, or lose electrons to try and become more stable. Atoms will gain, share, or lose electrons until they have a stable 8 valence electrons in their outer shell which is called an octet, which is stated in the octet rule. See the attached links for information on the octet rule.
They share electrons when they try and corm covalent or ionic bonds. This is because the atoms want to gain a full outer shell. So when they share electrons they can have full shells.
Atoms gain lose or share valence electrons in a way that makes the atoms more stable
A completely filled shell of electrons has 8 electrons.
do atoms of a covalent bond lose r share electrons
