Profit is producer surplus, minus fixed costs. In other words, its price minus variable costs. Profit, however, is price minus total cost. Since fixed cost is never negative, profit will always be less.
The atom is about 10-10 meters (or 10-8 centimeters) in size. This means a row of 108 (or 100,000,000) atoms would stretch a centimeter, about the size of your fingernail. Atoms of different elements are different sizes, but 10-10 m can be thought of as a rough value for any atom.
A Neutron weighs more than a proton. Than an electron. A Neutron weighs the most, and an electron weighs the least. A proton is in the middle. Although there are these three â¦ sub atomic particles, an atom is made up of 99 percent empty space! But from greatest to least in mass, it goes neutron, proton, then electron!
