How do you determine if a molecule is over all polar or non polar by finding if it a asymmetrical or symmetrical?
First, you should determine the geometry of the molecule. How many atoms or lone pairs are associated with the central atom? Is the molecular geometry linear, trigonal planar, tetrahedral, etc. Secondly, you need to determine the electronegativity of the atoms bonded together in the molecule. Polarity is all about electronegativity and how tightly bound electrons are to particular atoms in a molecule. Lone pair electrons on the central atom are obviously quite electronegative and should be accounted for as such. Halogens and other extremely electronegative atoms will provide a strong negative charge due to their affinity for electrons. If the molecule is symmetrical it is to be expected to be non-polar, and if it is asymmetrical it would be expected to be polar, but this is not always the case. For instance, a water molecule is symmetrical, but it is polar due to the pull of the lone pair electrons of the oxygen atom.
How many electrons does on atom of carbon contain?
In all there are 6 electrons, but the electrons are distributed over 2 shells. In the first shell, there are 2 electrons, and in the second there are 4 electrons. Note that this applies to the neutral atom of carbon.
What makes water a excellent solvent?
Water is a good solvent due to its polarity. The single Oxygen molecule and two Hydrogen molecules do not share electrons equally, the Oxygen molecule takes precedent over the Hydrogen molecules. The Polarity and in some small part, the small molecular size makes water the, "Universal Solvent".
Electrons found in the outer shell or orbital are called?
These electrons are called "outershell electrons" or "valence electrons."
Why are some molecules dipoles?
Because of the difference in electronegativities between atoms in a molecule, the electrons in a molecule can be drawn more strongly to one part of the molecule over another. If one region of a molecule is asymmetric and accompanies this difference in electronegativity, a dipole moment results. Examples: 1) water - H-O-H - oxygen more electronegative than hydrogen...oxygen side is more negative than hydrogen side 2) ammonia - NH3 - pyramidal structure of ammonia leaves hydrogen with one unshared pair of electrons...which makes the unpaired side more negative than the side with three hydrogen atoms However, even with dipole moments within a molecule, symmetries can prevent a net dipole moment from forming. An example is carbon tetrachloride (CCl4). In this molecule, dipole moments exist between chlorine atoms (more electronegative) and the central carbon atom (less electronegative). However, because of the tetrahedral symmetry of the molecule, no net dipole moment is formed.
Is fresh water evenly spreaded out over the earth?
fresh water is evenly distributed over earth
Are general somatic receptors distributed evenly over the body?
no
Volcanoes are fairly evenly distributed all over the world?
false
How are earthquakes distributed on the map are they scattered evenly over earth's surface are they connected in definite zone?
They are most common at plate boundaries.
What is an equipotential surface?
It's a surface over which electric charges are evenly distributed, caused by the mutual repulsion between charges of the same polarity.
What is equipotential surface?
It's a surface over which electric charges are evenly distributed, caused by the mutual repulsion between charges of the same polarity.
Are non-renewable resources evenly spread over the earth?
No they are not evenly distributed. Some parts of the world are have more oil than others. Other countries have more coal than others. Its just the things turned out geologically for everybody.
What is evenly dispersed?
Evenly dispersed means something is spread out evenly over an area or among people. Money can be evenly dispersed as well as liquid or matter can be evenly dispersed over a surface.
How can you tell that 4 over 5 is in simplest form?
You can tell that 4/5 is in its simplest form because 5 is a prime number. The 5 is not evenly distributed unless it is by itself or the number 1.
Why is the total electrical charge of a water molecule neutral?
there are no valence electrons left over after the two H atoms combine with the O atom.
