How many covalent bonds does helium form
WebDec 15, 2024 · Because of the relative stability, these atoms often form covalent bonds rather than ionic bonds that need a charge. One example is Carbon. It has 4 valence electrons, so it can make a 4+ or a 4- charge. But because of its relatively stable half filled orbital, most of the time it takes part in covalent bonding like in organic molecules. WebAug 19, 2024 · These four electrons can be gained by forming four covalent bonds, as illustrated here for carbon in CCl 4 (carbon tetrachloride) and silicon in SiH 4 (silane). Because hydrogen only needs two electrons to fill its valence shell, it is an exception to the octet rule and only needs to form one bond.
