ionic
Two electrons are trasfered from magnesium to oxygen and ionic bond is formed.
metallic bond
Bismuth
If the electrons are "stolen" from the metal by the nonmetal, an ionic bond is formed. If the electrons are shared between the metal and the nonmetal, a covalent bond is formed. If the electrons "resonate" between the metal and the nonmetal, a resonance bond is formed.
Electrons. (Or positrons if you're talking about antimatter)
covailant bond
covalent bond
With a covalent bond, atomic nuclei are sharing some of their valance electrons, which means that the electrons are in orbit around both (or all of) the nuclei in question. With an ionic bond, valance electrons are transferred from one atom to another. Once transferred, the electrons orbit only around the atomic nucleus that has received them.
Covalent bonding is when electrons are shared , Ionic bonding is when electrons are "pulled" or "stolen" from an atom with a smaller electronegitivity
covalent bonds
Two electrons are trasfered from magnesium to oxygen and ionic bond is formed.
metallic bond
Valence electrons are important because they are the electrons that each atom uses to bond or that can be stripped from the atom to create an ion. Non-valence electrons are not easily removed from the atom and are not used for bonding or transfer.
this means that there is a single covalent bond
Bismuth
If the electrons are "stolen" from the metal by the nonmetal, an ionic bond is formed. If the electrons are shared between the metal and the nonmetal, a covalent bond is formed. If the electrons "resonate" between the metal and the nonmetal, a resonance bond is formed.
Given that electrons repell other electrons while attracting protons in atomic nucleii, electrons interact in covalent bonds by finding an arrangement which brings them as close as possible to as many protons as possible while remaining as far as possible from other electrons. The particular feature of a covalent bond which differentiates it from other types of bonds is that a given electron does not limit itself to a single atomic nucleus, but orbits multiple nuclei.
