2015年10月23日 · "sp"^3"d" In order to determine the hybridization of the central phosphorus atom in phosphorus pentafluoride, "PF"_5, you must first draw the compound's Lewis structure. The molecule will have a total of 40 valence electrons, 5 from the phosphorus atom, and 7 from each of the five fluorine atoms. The phosphorus atom will be the molecule's central atom. It …

2016年8月9日 · Phosphorus pentafluoride When naming binary covalent compounds (compounds that are composed of 2 different nonmetals), you want to: Name the first element. You can obtain the name directly from the periodic table. The symbol, P, tells us that we are dealing with the element phosphorus Name the second element by using its root name and change the ending …

2014年10月9日 · the hybridization of PF_5 is sp^3d . In PF_5 , the valence electrons of phosphorus are 5. and we take the oxidation state of halogens as 1. So, for one F , electron is 1 and for F_5 the no. of electrons is 5. therefore, (from phosphorus and fluorine) 5-5=0 electrons = 0 lone pairs. there are 5 sigma bonds in this compound. So, 5 sigma bonds + 0 lone pairs = 5. -> …

Orbital hybridization can determine how many bonds an atom can form and the shape of molecules.. For example, using the Aufbau principle, Hund's rule and the Pauli exclusion principle we would write the following electron configuration for carbon

2014年5月8日 · The VSEPR shape of the molecule "PF"_3 is trigonal pyrimidal. We can use VESPR theory to predict a trigonal pyrimidal shape for the molecule PF_3 because of its AX_3E status. VESPR stands for valence shell electron pair repulsion. This theory basically says that bonding and non-bonding electron pairs of the central atom in a molecule will repel (push …

2016年3月6日 · Trigonal pyramid, Tetrahedral, 107^@. The Lewis structure of PCl_3 is the following: This is under the form of AX_3E where X represents the bounded groups Cl and E represents the lone pairs. The geometric shape is: Trigonal pyramid The electron-pairs arrangement is: Tetrahedral This is similar to the ammonia molecule NH_3. The bond angle is …

2015年6月25日 · The hybridization of the chlorine atom in ClF_5 is sp^3d^2. Chlorine pentafluoride, ClF_5, has a total number of 42 valence electrons: 7 from the chlorine atom and 7 from each of the five fluorine atoms. The Lewis structure of the chlorine pentafluoride molecule looks like this The five fluorine atoms will be bonded to the central chlorine atom via single …

2014年2月14日 · Arsenic has 5 valence electrons. It's electron configuration is 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^3. It's outermost shell (4s and 4p) has 5 electrons, these are the valence electrons.

2018年4月22日 · Ground state, neutral arsenic atoms have five valence electrons. Refer to the explanation. For the representative elements, groups 1,2, and 13-18 (IA-VIIIA), the number of valence electrons in their atoms can be determined from their group number. For groups 1 and 2, the group number is the number of valence electrons. For groups 13-18, the number of …

2016年5月12日 · We need a balanced chemical equation, before we determine the reagent in excess. I think it is chlorine gas. 1/4P_4 +5/2Cl_2 rarr PCl_5 This is of course a redox reaction, and establishes the stoichiometry. One equiv of phosphorus is oxidized by 5/2 equiv of chlorine gas. "Moles of phosphorus ATOMS" = (23.0*g)/(31.00*g*mol^-1) = 0.742*mol. "Moles of …
