The Si has no lone pairs, but each F has 6 lone pairs. Thus 6 x 4 = 24 lone pairs, total.
Yes it is bent, with 105 degree bond angle
The valence electrons of O is 6 and F is 7. 7x2= 14 + 6 =20 electrons in totalEach Fluorine makes a single bond with the oxygen atom. so that's 2 bonds right there.then fill up the fluorines so that they are satisfied. 16 electrons have now been used up. But the oxygen atom is still unsatisfied so you must give the oxygen atom 2 lone pairs. the total is now 20 electronsnow the hybridization of the oxygen atom which in this case is the central atom is determined by adding the total # of bonds together, it has 2 bonds with Fluorine and two lone pairs, add them up and u get 4 total bonds. 4 total bonds is = to sp^3
The oxidation number for oxygen in most compounds is -2. Since there are two oxygen atoms in F2O, this gives a total charge of -4. Therefore, the oxidation number for each fluorine atom in F2O is +2 to balance out the overall charge to zero.
Difluorine monoxide, or oxygen difluoride, has OF2 for its chemical formula. Has one of the lowest melting points of any compound, 30 K. Has been used as a biological medium in the SF novel Camelot 30K by Robert Forward, for life on a planetoid in the Oort Cloud.
Fluorine is hardly soluble but it might react with water in two different ways.Possibly:2 F2 + 2 H2O -- > 4 HF + O2(g) or2 F2 + H2O + OH- --> F2O + HF2- + H2O
The naming of covalent compounds follows a convention where the first element is named first, followed by the second element with an "-ide" suffix. In the case of Cl2O, it is named dichlorine monoxide because there are two chlorine atoms and one oxygen atom. Whereas F2O is named oxygen difluoride because there are two fluorine atoms and one oxygen atom.
Oxygen and fluorine are both non-metals which results in a covalent bond.
It is an IONIC compound as it involves 2 non-metals.
In the periodic table, oxygen is in Group VIA and fluorine is a halogen (Group VIIA) Oxygen has 6 valence electrons and normally can form 2 single or 1 double bond (excluding the cases of its coordinate covalent bonds). Fluorine has 7 valence and it can form only one single bond. Therefore, for each O atom, 2 F atoms are needed to complete their octets to form a stable compound. Fluorine is the most electronegative element, and attracts the bonding electrons to itself more than O. Therefore, the fluorine sides of the molecules become partially negative and oxygen become partially positive. (This is the single compound in which O has positive oxidation number). If the molecule were linear, the centers of the positive and negative charges would coincide with each other, and the molecule would be nonpolar. But, because of the two nonbonding electron-pairs in the valence shell of O atom, these pairs and bonding electron-pairs repel each other and the shape of the molecule becomes angular (bent) like water. This causes an uneven charge distribution (separete centers of - and + charges) and the molecule becomes polar.
Group 1 and 2 elements have 1 and 2 valence electrons respectively. Removal of these electrons will result in stable noble gas electronic configuration. Group 17 and 16 elements have 7 and 6 valence electrons respectively. Addition of 1 or 2 electrons to group 17 and 16 respectively will give them stable noble gas configuration. Hence these two groups are highly reactive and their elements will combine to form large number of compounds.

1. Elements on their own have an oxidation # equal to 0. (ex. in the chem equation Ca + 2AgCl --> CaCl2 +2Ag, Ca and 2Ag would have oxidation #s equal to 0.) 2. Ions in ionic compounds have an oxidation # equal to their charge. (ex. in the chem equation Ca + 2AgCl --> CaCl2 +2Ag, 2AgCl = Ag+1 and Cl-1, and CaCl2 = Ca+2 and Cl2-1.)
