How many elements are in Au?
Gold (the natural isotope 197Au) contain 79 protons, 118 neutrons and 79 electrons.
How would the structure of an atom of 202Hg have to be changed for the atom to become an atom of 197Au?
80Hg(202) has 80 p + 122 n79Au(197) has 79 p + 118 nThis is 1 proton and 4 neutrons less than in Hg
What do atoms of gold consist mainly of?
All atoms of any element contain protons, neutrons and electrons. Gold has only one natural isotope 197Au which has 79 protons and electrons and 118 neutrons. The main component of any atom is, as early researchers discovered, "empty space" in the region occupied by the electron cloud.
What type of isotope does gold form?
Isotope, Half LifeAu-194, 1.6 days Au-195, 186.1 daysAu-195m, 30.5 secondsAu-196, 6.2 daysAu-197, StableAu-198, 2.7 daysAu-199, 3.14 days
How many electrons and protons are in gold?
79 protons and electrons 118 neutrons
How many mass number have in 197Au?
Gold is a metal element. Atomic mass of it is 197.
How is francium currently produced or mined?
Francium is obtained only by a nuclear reaction: 197Au + 18O = 210Fr + 5 n
How many elements are in Au?
Gold (the natural isotope 197Au) contain 79 protons, 118 neutrons and 79 electrons.
How was francium formed?
1. As a natural element francium exist in infinitesimal concentrations in uranium ores (as a progeny of 235U in the decay chain). 2. Francium can be also obtained by nuclear reactions: 197Au + 18O----------210Fr + 5 n

80Hg(202) has 80 p + 122 n79Au(197) has 79 p + 118 nThis is 1 proton and 4 neutrons less than in Hg
What is the equation for alpha decay of mercury 201?
The equation for alpha decay of mercury-201 is: ^201Hg -> ^197Au + ^4He This means that mercury-201 decays into gold-197 and helium-4 by emitting an alpha particle.
Francium was obtained from?
Francium was first obtained by Marguerite Perey in 1939 from the radioactive decay process of actinium. It is a highly unstable and rare alkali metal that is found in trace amounts in uranium and thorium minerals.
How many neutrons does the the common isotope of gold have?
Atomic weight is neutrons plus protons. If the atomic weight is 197, we subtract the number of protons which we know is 79 because that's what makes it gold, we get 118.

Are the atoms in a piece of gold the same as each other or are they different?
Yes, while Gold (Au) does have a number of isotopes (195Au, 196Au, 198Au and 199Au), these are all synthetic (made by man) and unstable. The only stable isotope of Gold is 197Au, and his means that all the atoms in a piece of natural gold are indeed 100% the same as each other .
How many electron and protons and neutrons does gold have?
Gold, with the atomic number 79, has 79 protons in its nucleus. In a neutral atom, the number of electrons is equal to the number of protons, so gold also has 79 electrons. The number of neutrons can be calculated by subtracting the atomic number from the atomic mass of gold, which is typically around 197. This gives gold approximately 118 neutrons.
