75 g KMnO4 = molecules KMnO4 7.23 × 1024 Al atoms = grams Al 9.23 × 1023 Au atoms = moles Au 125 g H3PO4 = molecules H3PO4 0.75 moles CO2 = total atoms

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
