Crystal structure of gold
WebMar 26, 2024 · Gold has a mass of 197 atomic mass units. Subtract the number of protons from the atomic mass. For gold, 197 – 79 = 118. Gold has 118 neutrons. Gold’s nucleus, then, contains 79 protons and 118 neutrons. The additional neutrons reduce the repulsion between the positively charged protons. The nuclear forces bind the nucleus together. WebGold has a face-centered cubic crystal structure; thus there are 4 gold atoms per unit cell ( Figure 1 ). Since gold's lattice parameter is 4.08 Å, its unit cell has a volume of 0.0679 …
