why does water a polar covalent molecule contain ions

First of all, a single water molecule consists of an oxygen atom attached to two hydrogen atoms. Each of the hydrogen atom is bound to the oxygen atom through a covalent bond. Why the bond is covalent can be explained by looking at the electronegativities of each atom. A covalent bond is a type of bond where the atoms involved share electrons in order to obtain an octet (8 electrons). Oxygen has 6 electrons, and by sharing electrons with 2 hydrogen atoms (each sharing one electron), it attains an octet. The hydrogens only need two electrons (exception to octet). This is as opposed to an ionic bond such as in NaCl where one of the atoms completely transfers the electron to the other. ...

 why does the moon have less gravity than earth

why does the moon have less gravity than earth

m1 and m2 are masses (in kilograms) and d^2 is the distance (in meters) squared between the centers of the two objects (e. g. you and the center of the earth). G is a constant, the gravitational constant, which is 6. 67*10^-11 when these units are used. Since this is a very small number, it means that gravity is a very weak force that you only really notice when there is a very large mass involved (like the earth or the moon). So, we take our equation and plug and chug. Mass of the Earth: 5. 98 x 10^24 kg (from http://pds. jpl. nasa. gov/planets/welcome/earth. htm) Mass of the moon: 7. 34*10^22 kg Radius of the moon: 1737. 4 km (from http://nssdc. gsfc. nasa. gov/planetary/factsheet/moonfact. html) You: 63. 5 (Say you weighed 140 pounds, your mass would be 63. 5 kg) F = (6. 67*10^-11) (5.
