197% := 197/100= 1 97/100
the answer is..... 38
1 and 197.
197 = CXCVII
An equation. b-432 = 197 b = 197+432 b = 629 Check: 629-432 = 197
All gold isotopes have 79 protons. If the gold atom has no electric charge it also has 79 electrons.
79
For gold-197, there are 79 protons (equal to the atomic number), 79 electrons (since atoms are electrically neutral), and 118 neutrons (subtracted from the mass number - atomic number = 197 - 79 = 118).
An atom with an atomic number of 79 has 79 protons in its nucleus. Since the atomic number represents the number of protons, this atom also has 79 electrons. The mass number (197) represents the sum of protons and neutrons, so subtracting the number of protons (79) gives the number of neutrons: 197 - 79 = 118 neutrons.
The mass number is the sum of protons and neutrons in the nucleus of an atom. In this case, an atom of gold with 79 protons and 118 neutrons would have a mass number of 197 (79 protons + 118 neutrons = 197 mass number).
Au-197 has 79 protons, 79 electrons, and 118 neutrons. The atomic number of gold (Au) is 79, indicating the number of protons. The isotope Au-197 specifies the atomic mass, which is the sum of protons and neutrons. So, subtracting the atomic number from the atomic mass gives the number of 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.
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.
The average number of neutrons in a gold atom is approximately 118.
197
Any neutral atoms has the same number of electrons as protons, and any atom has a number of protons equal to the difference between its mass number and neutron number. Therefore, this atom has 197 - 118 = 79 electrons.
For gold (Au), atomic number = 79, so it has 79 protons and 79 electrons. The number of neutrons can vary depending on the isotope of gold, but a common isotope, Au-197, has 118 neutrons.
