Document Summary
Cobalt atom smallest stable component of all matter. 0. 000549 amu define the volume of the atom. Number of protons + neutrons = mass number. Number of neutrons = mass number - atomic number. Atoms with the same number of protons, but different numbers of neutrons, are. To calculate average atomic mass: use an experimental percent abundance of each isotope of the element, multiply the percent abundance by the atomic mass of that isotope, sum the total mass of each isotope, group 1a alkali metals. Metals are on the left non-metals on the right of the bold zigzag from boron to polonium. Metalloids touch the line , b- poat building-block elements carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. Macronutrients needed in quantities over 100 mg per day. They are sodium, potassium, magnesium, calcium, phosphorus, sulfur, and chlorine. Micronutrients needed in quantities less than 100 mg a day, but are essential for health.
