Isotopes differ from each other according to their mass number. The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, ...

Gold (atomic mass = 197 u) has atomic radius = 0.144 nm. It crystallises in face centred unit cell. Calculate the density of gold. (No = 6.022×1023mol−1) View Solution An element crystallizes in face centred unit cell. What is the length of the side of the unit cell, if atomic...
The element gold is a pirate's booty and an ingredient in microcircuits. It's been used to make jewelry since at least 4000 B.C. and to treat cancer only in recent decades. It's in the pot at the end of the rainbow and in the coating on astronaut visors. Gold is an element that...
Gold (Au) has an atomic number of 79, which means each gold atom contains 79 protons in its nucleus. Gold’s atomic mass is 196.967, and its atomic radius is 0.1442 nm. Notably, this figure is smaller than the theoretical prediction....
The number of protons in the nucleus, the atomic number, determines the element. The total number of neutrons and protons in the nucleus determines the atomic mass number. Differing numbers of neutrons in a nucleus creates variants of the atom called isotopes. Isotopes can be unstable, likely ...
