Estimate the number of electrons in your entire body. besides assuming that your body is electrically neutral, clearly state any assumptions you make. (hint: you will want to refer to a list of the chemical composition of the human body.)

Average weight=137 pounds=62 kg=  electrons

Explanation:

First, we assume the average weight of an adult human is 137 pounds (62 kg), then we need the percentage of the mass of each element in the human body. Obtaining the molecular weight, and the number of electrons (assuming that your body is electrically neutral) per element using the periodic table. Finally, knowing that  Avogadro's number represents units (electrons, atoms, protons) in one mole of any substance; we can estimate  the number of electrons in the average human body (You can use your real weight to do the maths) with the  equation shown below:

Where:

- is the weight body multiple by percentage of the mass of each element.

- is the molecular weight of each element.

- is the number of electrons of each element.

- is the Avogadro's number

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

put the answers   and i could answer.
