During the formation of a covalent compound, two or more nonmetallic elements combine with the help of covenant bonds. The pairs of valence electrons shared in the formation of the covalent bonds are known as bond pairs of electrons. On the other hand...
Give the Lewis structure of BF4- and determine the number of valence electrons. How many electrons are in the Lewis structure of a nitrite ion (NO_2^-)? In the best Lewis structure for XeF4 , what is the formal charge on the F atom? a. +1 b...
Number of one-one functions = 0 if n < m…..(2)By the above formula, in our case the value of m is 4 and the value of n is 4.We can see that m = n.So we need to use equation (1):\[\text{Number of one-one functions = }{}^{n}{{P}_{m}}...
How many nonbonding pairs of electrons does the central atom Xe have in the molecule XeF4? (a) 1 (b) 2 (c) 3 (d) 4 (e) 5What is the structure of SiO_2? Can Si have more than 8 valence electrons?Determine whether BrCl would be best represente...
Each covalent bond formed represents a sharing of one valence electron pair between the participating atoms. This is a straight line in a Lewis structure that connects two elemental symbols. A participating atom may form less covalent bonds than its starting number of valence electrons. T...
For the sulfate ion, SO42-, draw the Lewis structure (by counting valence electrons of each atom). Determine the: a) electron-domain geometry b) molecular geometry c) hybridization d) Show the angle between the bonds in a drawing. Draw the Lewis structure fo...
