Given two people of different complexion, one short and chubby and the other one tall and thin, but same weight (180 lbs each): a> Do they have the same number of atoms in their bodies b> If not, will the percent difference be significant? Brian Clegg website. Also, the conclusion drawn, that 98% of the atoms in a human body are replaced every year, doesn't sound like the result of a physics experiment. 0 0. What about Hitler?" for an approximate number take the weight of your body in grams and multiply it by .75 then divide it by 18 (thats the molecular weight of water). It’s much easier to use scientific notation to denote the number of atoms in a human body: 7 x 10 27 atoms, meaning 7 with 27 zeroes after it. If all the space will be removed from the body’s atoms, we would reach the size of a grain of salt. The human body is an intricate piece of art consisting of a multitude of atoms, about 7 × 10 27 atoms, to be more precise. A human body can only generate between 10 and 100 millivolts [source: NanoMedicine]. Cell is formed by combining atoms. The mass of Atoms contained in a human body Thread starter corochena; Start date Mar 3, 2011; Mar 3, 2011 #1 corochena. This man doesnt have artificial limbs or fillings in his teeth. If we lost all the dead space inside our atoms, we would each be able to fit into a particle of dust, and the entire human species would fit into the volume of a sugar cube. Combining atoms to make molecules. The number of atoms in one person is almost too big to write out. Before you begin to study the different structures and functions of the human body, it is helpful to consider its basic architecture; that is, how its smallest parts are assembled into larger structures. (How many atoms are in the human body?) Brian Clegg is an English science writer. A "radical" is an atom with an unbalanced electrical charge, and it will seek to steal electrons from other atoms - such as the atoms of our body cells! 1 decade ago. our body is made up of numerous atoms my friend that u can't list them :D. Sulfur-oxygen-potassium-carbon-hydrogen … To answer this question, I'm going to start by talking about bigger things and moving us down into smaller things. I'm seeing the diameter of a carbon atom (in meters) is about 1.52 × 10-10 m ( 0.000 000 000 154 m) And, here is a calculation for the volume of the human body (in meters), at about 0.07 m 3 for a 70 kg person. If the atomic nucleus had the size of a soccer ball, the nearest electron would be about 800 meters away from it. It is hard to grasp just how small the atoms that make up your body are until you take a look at the sheer number of them. Relevance. This is really just an estimate, but it's going to be a good one. Answer Save. Ashley. Relevance. We can calculate the number of atoms in your head if we know the density and a constant called Avogadro's number. Let's start with the human body.
