Challenge Question: Atoms on the periodic table are neutral. Determine the number of electrons and valence electrons Sodium (Na) has. Will sodium give
away the electron, take electrons or have not change? Explain your answer.

i dont know the answe

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
