Quadricovalent
means that the element
can form 4 covalent bonds. Carbon is an example, as are the other members of group 14,
Unielectrovalent
means an element
that forms a singly charged ion, such as the group 1 metals,
Li, Na, K etc which form positively charged cations, Li+, Na+, K+ etc or the halogens F, Cl , Br, I which form singly charged anions, F-, Cl-, Br- I- . The term can also be aplied to polyatomic species that are cations e.g. NH4+ or anions e.g. SO42-

Is N2O5 ionic or covalent?
There is no known species as N2O6. NO3 is a transient planar molecule, with an unpaired electron. N2O5 in the solid is NO2+ NO3- in the vapour and solution it is molecular, probably O2-N-O-NO2. N2O4 is a planar molecule O2N-NO2
Do polar covalent bonds have a lower or higher electronegative?
One species has at least 1.4 greater electronegativity than the other species to make a polar covalent bond. Water is a good example of this. H2O Hydrogen = 2.2 electronegativity Oxygen = 3.44 electronegativity 3.44/2.2= 1.56 this is enough variance to make a polar covalent bond
Is SO3 an ionic bond or a covalent bond?
SO3 as sulfur trioxide is polar covalent bonded. As the sulfite ion, it is covalently bonded as the ion but forms ionic bonds with other species.
Is the chemical compound CH a covalent bond?
A hydrogen atoms binds to a carbon atom by sharing an electron pair... a covalent bond. Covalent bonds are formed by non-metals, like hydrogen and carbon; ionic bonds are formed by metals and non-metals, like NaCl.
Compare and contrast ionic bonds and convalent bonds?
Ionic bonds are usually thought of as the electrostatic forces of attraction that result from a species "donating" electron(s) to another species, thus resulting in a positively charged ion (cation) and a negatively charged ion (anion). Covalent bonds are thought of as species "sharing" electron(s) with another species, so there's a sharing of electrons and a joining of their electron clouds. However, most compounds are not purely ionic/covalent; there's almost always a certain degree of ionic character and covalent character in every compound and bond.
