2.2 Fundamental Concepts. Atoms are composed of electrons, protons, and neutrons. Electron and protons are negative and positive charges of the same magnitude, 1.6 в 10-19 Coulombs. The mass of the electron is negligible with respect to those of the proton and the neutron, which form the nucleus of the atom. The unit of mass is an atomic mass unit (amu) = 1.66 в 10-27 kg, and equals 1/12.

An up-to-date periodic table with detailed but easy to understand information.

Mar 29, 2019  · Mass percent tells you the percentage of each element that makes up a chemical compound. Finding the mass percent requires the molar mass of the elements in the compound in grams/mole or the number of grams used to make a solution. It is simply calculated using a basic formula dividing the mass of the element (or solute) by the mass of the compound (or solution).

Table 1-1 shows that, although the solute compositions of ECF and ICF are quite different, the total numbers of cations and anions in all body fluids are equal to maintain electroneutrality. The most abundant cation in the ECF is sodium (Na +).Most of the body Na + is in the extracellular space. Approximately 70% of body Na + in humans is exchangeable, and 30% is fixed as insoluble salts in.

The modern periodic table is a device scientists use to organize the elements with respect to the atomic numbers of the elements rather than the mass. of elements that are useful when uncombined with other atoms in the form of molecules.
