Boron trifluoride has a maximum covalency of 4 because boron has three valence electrons and each fluorine atom contributes one electron. This allows boron to form four covalent bonds by sharing its three electrons with three fluorine atoms and the fourth electron from one of the fluorine atoms. This results in a stable structure with each atom having a full outer electron shell.

How many covalency number are possible for sulfur?
Sulfur can exhibit a covalency number of 2, 4, or 6, depending on the molecule it is in. In H2S, sulfur has a covalency of 2, in SO2 it has a covalency of 4, and in SF6 it has a covalency of 6.
Is boron trifluoride ionic?
Yes. Fluorine has an electronegativity of 4 and Boron has an electronegativity of 2. If the difference in the electronegativity of two elements is greater than 1.8, then it is ionic.
What is the covalency of carbon?
Carbon typically forms covalent bonds with other elements, sharing electrons to achieve a stable electron configuration. Each carbon atom can form up to four covalent bonds, resulting in a covalency of 4.

6 Write a chemical equation showing the reaction between ammonia and boron trifluoride BF3 in a Lewis acid-base reaction Show how the covalent bond forms?
The reaction between ammonia and boron trifluoride, BF3If you have recently read the page on covalent bonding, you may remember boron trifluoride as a compound which doesn't have a noble gas structure around the boron atom. The boron only has 3 pairs of electrons in its bonding level, whereas there would be room for 4 pairs. BF3 is described as being electron deficient.The lone pair on the nitrogen of an ammonia molecule can be used to overcome that deficiency, and a compound is formed involving a co-ordinate bond.Using lines to represent the bonds, this could be drawn more simply as:The second diagram shows another way that you might find co-ordinate bonds drawn. The nitrogen end of the bond has become positive because the electron pair has moved away from the nitrogen towards the boron - which has therefore become negative. We shan't use this method again - it's more confusing than just using an arrow.
What is covalency of nitrogen in N2O5?
wcovalency means the max number of electron an atom can share with others. nitrogen can share 5 but due to the absence of d orbital it can only share 4. therefore the actual covalency in 4.
