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-
What else can I help you with?
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
Is ch2o a Lewis acid or base?
Formaldehyde (CH2O) is not typically considered a Lewis acid or base on its own. Its role as an acid or base would depend on the specific reaction conditions and the species it is interacting with.
Which statement is most likely to be true of the chemical species that donates electrons to a coordinate covalent bond?
The chemical species likely has a lone pair of electrons available to donate to form the coordinate covalent bond. This species is often a Lewis base, which means it can donate its electron pair to form a bond with a Lewis acid.
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
Polyatomic ion vs. covalent compound?
A polyatomic ion is a charged species composed of two or more atoms held together by covalent bonds, giving it a net charge. In contrast, a covalent compound is a molecule formed when two or more nonmetal atoms share electrons to form covalent bonds, with no overall charge.
