197 - 79 = 118
197% := 197/100= 1 97/100
1 and 197.
197 = CXCVII
the answer is..... 38
An equation. b-432 = 197 b = 197+432 b = 629 Check: 629-432 = 197
79
Gold's atomic number is 79 and its atomic mass is 197 (on avarage) 197-79=118 neutrons.
mass number is simply the addition of the proton number and neutron number. we also know that proton number of the element is similar to atomic number. we also know that 79 + (197-79) is the no. of neutron no. of the gold. hence when atomic no. of the gold is 79 its atomic mass or mass number is 197.
All gold isotopes have 79 protons. If the gold atom has no electric charge it also has 79 electrons.
118 Neutrons are in the Element Gold.The number of neutrons can vary for an element, but for gold the stable isotope has 118 neutrons.This is gold-197 (197-Au) and includes virtually all naturally occurring gold on Earth.Synthetic radioisotopes of gold are 195-Au, 196-Au, 198-Au, and 199-Au.All atoms of gold have 79 protons, and neutral atoms have 79 electrons.
197
I know that there are Electrons:79 Protons: 79 Nuetrons: 118
the element is gold (Au) it has 79 neutrons and 79 electrons. this is because it is not an isotpic or ionice subatance as of yet. the atomic weight is 196.97amu
Atomic mass is the number of protons plus the number of neutrons so, in the case of gold, the mass number = 79+118 which is 197
Gold is a metal element. Atomic mass of it is 197.
The atomic number of gold (Au) is 79.The atomic weight of gold is 196.9665 grams per mole.Gold has 79 protons, 118 neutrons and 79 electrons.See the Web Links and the Related Questions to the left of this answer for a periodic table and more information about this element.Gold is a very rare element. Atomic number of it is 79.Gold is a d block element. atomic number of gold is 79.
