How many protons are found in Platinum 197?
78 protons, 78 electrons and 119 neutrons
Gold has atomic number 79 and mass number 197 how many electrons protons and neutrons are you going to find?
You will have 97 protons and 100 neutrons. But I am not sure about electrons...
A neutral atom of gold has a mass number of 197 and has 118 neutrons how many electrons does it have?
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.
How many protons electrons and neutrons does an atom with an atomic number of 79 and a mass of 197?
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
An atom of gold with 79 protons 79 electrons and 118 neutrons. What's the mass number?
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

How many neutrons are in gold?
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.

How many protons does gold 197 have?
All gold isotopes have 79 protons. If the gold atom has no electric charge it also has 79 electrons.
How many neutrons in gold?

An atom of gold with 79 protons 80 electronsand 118 neutrons would have a mass number of?
197
Mercury-202 has how many neutrons in its nucleus?
Mercury has the atomic number 80 so has 80 protons. Work out the neutrons by taking the protons away from the total mass. Other isotopes of mercury are mercury-196, 197, 198, 201, 202 and 204. Each will have a different number of neutrons, giving it a different mass, bat always the same number of protons. That means always the same number of electrons too, so therefore the same chemical behaviour.
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.
How does the mass of an atom relate to the three main types of subatomic particles found in a atom?
The three main types of subatomic particles, indeed, the only three types, are protons, neutrons, and electrons. Electrons are very light; protons and neutrons have about 2000 time as much mass, and very similar masses to one another. They are very close also to a mass of 1 Dalton (defined as exactly 1/12 of the mass of a carbon-12 atom) So the mass of an atom in Da is given to a very good approximation by the number of (protons + neutrons). It is not exact because -- protons and neutrons do not have exactly the same mass -- neither a proton nor a neutron has a mass of exactly 1 Da -- all of these particles are very light, and the protons and neutrons are very tightly bound together in the nucleus, so the relativity theory mass equivalent of the nuclear binding energy (E = mc2) makes a significant difference. Examples: gold-197 has 79 protons, 118 neutrons, mass number 197, atomic mass 196.9666 iron-56 has 26 protons, 30 neutrons, mass number 56, atomic mass 55.9349 helium-4 has 2 protons, 2 neutrons, mass number 4, atomic mass 4.00260
