chemical symbol[′kem·i·kəl ′sim·bəl] (chemistry) A notation for one of the chemical elements, consisting of letters; for example Ne, O, C, and Na represent neon, oxygen, carbon, and sodium. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by...
Numbers in a formula are used to denote when a molecule contains more than one atom of an element; the numbers are written below the element's symbol. For example, CO2is the formula forcarbon dioxide. It tells you that each molecule has one carbon atom and two oxygen atoms. Some formula...
Which chemical element has the symbol F? What is the element symbol for cobalt? What is the chemical element cobalt? Which symbol represents an isotope of carbon? What chemical element is W? What is the symbol for iodine? What is the chemical element antimony?
Begin by memorizing all formulas that contain only two elements, such as CO(carbon monoxide). Then go over all of the formulas that have three elements, such as HCN and so on. When you've finished all six formulas, which should cover most DNA chains, come back and tell us how you did...
If you wait for another 5730 years, about 25% of the container will be composed of the original carbon, and the other 75% will be atoms of nitrogen. Some elements, especially the heavier ones, have half lives of just a few milliseconds. For example, ununbium-277 (Uub) has a half-...
