2024年6月5日 · The electron dot structure for H2O shows that the O has 2 lone pairs of electrons. So the answer would be 4 non bonding electrons are in a water molecule. This answer is:

2014年11月28日 · Hydrogen bonding does not directly affect the structure of a single water molecule. It does, however, strongly influence the interactions between water molecules in a solution of water. Hydrogen bonding is one of the strongest molecular forces second only to ionic bonding. When water molecules interact, the hydrogen bonds pull the molecules together …

2015年4月29日 · The geometry of molecules depends on the number of atoms present in the molecule and the angles between bonds in the molecule. For example, molecules CO_2 and H_2O both have three atoms. The angle between bonds is 180° in carbon dioxide making this molecule linear. The angle between bonds in water is 104.5° making water a bent molecule. …

2022年4月28日 · The minimum magnification for microscope to see a water molecule would be about 1,000,000 times, but at 10,000,000 you could make out the structure. Tags Science Subjects. Animals ...

2016年4月29日 · Bent. The central oxygen atom has 2 non-bonding pairs of electrons, and 2 pairs of shared bonding electrons, each to a hydrogen atom. The arrangement of the electron pairs around the central oxygen is tetrahedral, with the non-bonding pairs taking up slightly more space than the bonding pairs, but since we don't "see" the the electrons but only the atoms, the …

2024年5月28日 · A water molecule is held together by a polar covalent bond between the oxygen atom and the hydrogen atoms. The oxygen atom attracts the shared electrons more strongly, creating a partial negative ...

2014年5月8日 · Water has tetrahedral shape, or to be more precise, bent shape. On this picture you can see tetrahedral shapes of water, ammonia and methane. But it is better to say that methane has tetrahedral shape, ammonia trigonal pyramidal and water bent.

2017年11月18日 · Refer to the explanation. In the Lewis structure for "H"_2"O", the central oxygen atom is bonded to two hydrogen bonds. The bonds between oxygen and hydrogen are single covalent bonds. The central oxygen atom has two lone pairs of electrons, which is why the water molecule has a bent shape.

2016年2月28日 · Water is made up of two hydrogen and one oxygen. But this also works, because the line represents the shared electrons.

2015年11月24日 · About the O atom in the water molecule there are 2 non-bonding lone pairs, and 2 bonds to hydrogen. VSEPR tells us that the most energy stable disposition of these electron pairs is as a tetrahedron. But we describe molecular shape in terms of the bound atoms: that is as a "bent" H-O-H structure where the lone pairs compress the /_OH_2 bond angle.
