What is the scientific definition of graph?
A diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles.
What is the electron pair geometry for so3?
The molecular geometry of the AsO2- ion is bent (because of the lone electron pair with the central arsenic atom, making the O-As-O bond angle very obtuse) but its electron domain geometry is trigonal planar because there are three domains, with a 120 deg. angle between them.
What is considered a pair of jeans?
A pair of jeans, though called "a pair", is really only one article of clothing.
Why are pants called a pair of pants?
The have two leg sides,.......which is combined into a "pair" !
Which pair of resources is renewable?
Solar, water, wind, biomass, etc are the pair of resources that are renewable.
Which pair of ideas were central to the scientific revolution?
Observation and experimentation.
Can you figure out the pair of homonyms to match each pair of ideas?
Yes.
How many lone pair electrons are in ch2o?
There is 1 lone pair around the central C atom
What literary device consists of a pair of contradictory words or ideas?
l
Determining the Electron group geometry of a central atom?
EGG=(#lone pair electrons)+(# of bond pair electrons)
What is the atom bonded to central atom and lone pair on central atom of C2H2?
The question is not answerable. There is NO central atom in C2H2 (ethyn) and there's NO lone pair. All electrons are covalently shared in pairs: three pairs between C and C, one single pair in each C and H bond.
What is the electron pair geometry around the central atom of SeF6?
electron pair geometry: octahedral molecular geometry: octahedral
What is the electron pair geometry around the central atom of TEF6?
Octahedral
Why does a lone pair of electrons occupy more space on an atom?
It doesn't exactly occupy more space, but it has a different shape to a bond pair. In a bond pair we have two positive nuclei, with most of the density of the bonding electron pair between the atoms. The outer nucleus attracts the bond pair outwards from the central atom. In a lone pair there is only the central atom to attract the electrons, so they are pulled in more than the bond pair, producing a fatter, squatter shape. This means that more of the electron density is near the central atom than with a bond pair, which makes it more effective at repelling the other electron pairs. Thus there is a difference in the amount of repulsion between different sorts of pair, meaning that he angles between them are different too, in the order, from greatest to least, lone pair-lone pair, lone pair-bond pair, bond pair-bond pair.
How many lone pairs of electrons exist on the central atom in ammonia?
One lone pair. The central atom is N (nitrogen) which has 5 valence electrons. Three of them are shared with 3 hydrogen atoms, leaving 2 electrons (1 lone pair) on the N.
What is the change in bond angle down a group when central atom has lone pair?
there is repulsion between lone pair and bond pair for example in water molecule oxygen has lone pair which repells the bond pair due to this bond angle decreases simply ddue to repulsion btween lone pair to lone pair or lone pair to bond pair angle varies
