Since they can still be unstable...nuetral atoms have the same amount of protons to electrons but to be stable they need to fill up there outer shell by gaining or losing electrons
The melting point of the solid form of water, which is ice, is 0°C. When we convert both temperatures to kelvin by adding 273 to each we get the melting point of copper as 1357K and that of ice is 273K. Then, dividing the melting point of copper by the melting point of ice, both in absolute temperature scale. The answer would be 4.97. Thus, the energy of molecules of copper is approximately {five} times compared to that of water

A mixture can be separated by a physical means because there is no chemical bond between the constituents
Polar and non polar bonds only have to do with non metals. non polar have to do with non metal diatomic molecules while polar bonds deal with non metals that have different electronegativities
