How many protons are in an atom of tin? how many electrons are in an atom of tin? how many neutrons are in an atom of tin? round your answer to the nearest whole number.

50     50    69

Explanation:

How many protons are in an atom of tin?   50

How many electrons are in an atom of tin?   50  

How many neutrons are in an atom of tin? Round your answer to the nearest whole number.  69

Explanation: The average weight is 118.71, so, on average, a tin atom has 69.71 neutrons (118.71 -50). A stable atom of Tin (Sn)

Atomic number: 50 Protons: 50 Electrons:50 Neutrons: 69 Mass Number: 119 (rounded-off) The Mass number is equal to the sum of protons and neutrons.

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 .

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
