Chemistry and physics are so closely related that sometimes the fields overlap. which of the following experiments might both chemists and physicists do? a. study how the sun's heat affects pollutionb. study how well a pesticide works on plantsc. study the life cycle of a mothd. study what kind of chemicals enter milk

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

since electrons are negative the answer is neagtaive

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.

5.6⋅10−^19  j
