How many electron groups are around the central phosphorus atom?
The answer is 1. This is because the only atom with lone paires is phosphorus and it only has 1.
Why ClO2 do not form dimer but NO2 can?
in ClO2 ,the central Cl atom is sp2 hybridized with O-Cl-O angle of 118 degree.....the bond lengths are both 149 pm .....Cl-O bond has appreciable double bond character due to p(pi)-d(pi) bonding..the molecule is paramagnetic since it has one electron in a p-orbital... now often odd electron molecules dimerizes in order to pair the electron but ClO2 does not ...this is probably due to the reason that odd electron is delocalized as it is involved in p(pi)-d(pi) bonding.. in contrast the odd electron on N in NO2 is localized as nitrogen does not contain a d orbital...
Is Ammonium ion a molecular ion?
The ammonnium ion NH4+ is a charged species, molecular ion, due to the fact the central atom nitrogen has insufficient non bonding electron pairs. For nitogen to be a neutral species is must contain one and only one non bonding pair. For example NH3 has three attached hydrogens and one non bonded electron pair. In contrast NH2- has to hydrogens attached and two non bonded electron pairs. The easy way way to remember the trend using the periodic table is CNOF 0123, where the letters stand for elements carbon to fluorine and the number trend that follows is the number of non bonded pairs required for a neutral species.
Is phosphorus triodide polar or non-polar?
Non Polar The bonds themselves between phosphorus and chlorine are polar because chlorine is more electronegative than phosphorus. However the molecule is non polar because the five regions of electron density are the same.
What is circular to elliptical structure developed by downwarping of the central strata is a?
a basin
What is the hybridization of the central sulfur atom in SF4?
It should be sp3d. first draw the Lewis structure. then you can see the central S atom has 4 bonding pair and 1 lone pair. then draw molecular orbital. Distribute electron according the bonding and lone pair. the paired electron represent lone pair in Lewis structure. and the other unpaired electron distribute in the molecular orbital represent the number of bonding pair in Lewis structure
A molecule having four total electron groups around the central atom has three bonding electron groups and one nonbonding electron group what is its molecular structure?
trigonal pyramidal
What determine the molecule geometry of a molecule?
Consider: Number of bonding domains on the central atom Number of non-bonding electron pairs (lone pairs) on the central atom
What determines the molecular geometry of a molecule?
Consider: Number of bonding domains on the central atom Number of non-bonding electron pairs (lone pairs) on the central atom
What is the electron-domain geometry of PF6?
The electron-domain geometry of PF6 is Octahedral, since the central atom Phosphorus has an electron pair geometry which is octahedral
If all of the electron groups around a central atom are bonding groups (that is there are no lone pairs) what is the molecular geometry for two electron groups?
linear
How many electron groups are around the central phosphorus atom?
The answer is 1. This is because the only atom with lone paires is phosphorus and it only has 1.
Are all atoms are similar in structure?
Yes. They all have a central nucleus with an electron probability cloud surrounding it.
What is the electron dot structure for beryllium fluoride?
BeF2 forms, with one beryllium central to the two fluoride ions. each fluorine has seven electrons to start, gaining one electron from beryllium each.
Determine the idealized bond angle for OF2?
Using VSEPR theory there are 4 electron pairs around the central oxygen , 2 of which are bonding and 2 are lone pairs. These electron pairs repel one another pointing approximately to the corners of a tetrahedron, the bond angle F-O-F would be approx 109.5. Not exactly as the lone pair- bonding pair repulsions are stronger than bonding pair - bonding pair repulsion which would lead to a reduction in the angle. This is observed as the bond angle is known to be 1030
What is the difference between the arrangement of electron pairs and the shape of the molecules?
The shape of a molecule only describes the arrangement of bonds around a central atom. The arrangement of electron pairs describes how both the bonding and nonbonding electron pair are arranged. For example, in its molecular shape, a water molecule is describes as bent, with two hydrogen atoms bonded to an oxygen atom. However, the arrangement of electron pairs around the oxygen atom is tetrahedral as there are two bonding pairs (shared with the hydrogen) and also two nonbonding pairs.
The arrangement of electrons in an atom is called?
A unit of matter, the smallest unit of an element, having all the characteristics of that element and consisting of a dense, central, positively charged nucleus surrounded by a system of electrons. The entire structure has an approximate diameter of 10 -8 centimeter and characteristically remains undivided in chemical reactions except for limited removal, transfer, or exchange of certain electrons.
