The central portion of the atom is the nucleus, which consists of protons and neutrons. Electrons orbit the nucleus similar to the way planets orbit our sun. The three basic particles of the atom are protons, neutrons, and electrons. See Figure 1-1, Basic Particles of the Atom. For a description of the basic particles of the atom, see Table 1-1.
Oct 22, 2017 · Answer The 20 percent NaCl solution means 20 g of NaCl/100 g of solution (read as 20 g of NaCl in a 100 g of solution). Since the question demands how many grams of NaCl must be added to 1000 g of water, we have to figure out the amount of water in the 20 percent of solution so that we can set up the correct conversion factor.
The molecular ion peaks (M+ and M+2) each contain one chlorine atom - but the chlorine can be either of the two chlorine isotopes, 35 Cl and 37 Cl. The molecular ion containing the 35 Cl isotope has a relative formula mass of 78. The one containing 37 Cl has a relative formula mass of 80 - hence the two lines at m/z = 78 and m/z = 80.
FOUR GENERATIONS OF COMPUTERS The first vacuum tubes computers are referred to as first generation computers, and the approximate period of their use was from 1950 to 1959.

Vectors are used to define positions on the maps via a letter/number grid. Most maps will also show a vector pointing north to define compass directions on the map. Vector Game. The axes are chosen in advance and marked, so you know which direction is +x and which direction is +y. For example, forward may be +x and right may be +y.
