Similarly, experiments serve as evidences for scientists to prove their views. Sometimes there are no possible experiments to prove a view. During such cases. mathematics is usually used, and the validity is proved by the fact that any further experiments taking into consideration this mathematical outcome turns out to be true. For e. g. the Avogadro's number as 6. 023 x 1023. This cannot be proved, since one cannot

you know your relationship is over when

Having a healthy sex life and one that suits both your libidos and sexual desires is important for every relationship, but if your bedroom time has gone from exciting and experimental to dull and repetitive then it's time to decide why.

" If you're not quite ready to call it a day, try bringing the zing back with a new, or introduce into the mix. If you're both still not jumping into the bedroom then maybe your relationship is more suited to being just a friendship. Sometimes,

 why does helium have 2 valence electrons

why does helium have 2 valence electrons

The octet rule states that atoms with eight valence electrons are most stable. The noble gases are the only non-transition-metal elements that have eight valence electrons in their neutral, ground state configuration, but atoms of other elements can produce a full octet -- an outer shell with eight electrons -- by gaining or losing electrons. Oxygen, for example, can gain two electrons to have a full octet, and potassium can lose one electron to have a full octet. These atoms with extra or fewer electrons, however, are known as ions, or charged particles. Because of this gain or loss of electrons, ions are more reactive than noble gases, which is why noble gases generally appear by themselves, rather than combined with other atoms to make chemical compounds. Of course, things can t be
