Platinum atom has 78 protons and electrons; the number of neutrons is variable and depends on the Atomic Mass of the isotope (atomic mass of the isotope - atomic number = number of neutrons).
The stable isotopes have 114, 116, 117, 118, or 120 neutrons.
Platinum has 6 naturally occurring isotopes, all of which have 78 protons. The number of neutrons can vary, but the most common isotopes have between 116 and 118 neutrons. The full list of isotopes is:
The most common isotope of platinum has 117 neutrons.
Platinum - Atomic number 78 has 7 isotopes with Atomic masses of 190,192,193,194,195,196 and 198.
Subtract the Atomic number from the Atomic Mass values and you will end up with the number of Neutrons present in each isotope.
eg. the most common isotope 195Pt has (195-78) = 117 neutrons.
The number of electrons in any atom always equals the number of protons (to make the atom electrically neutral). The atomic number of any element tells you how many protons there are in the nucleus of an atom of that element. The atomic number for platinum (Pt) is 78, and the atomic weight is 195.
Thus, it will have 78 protons.
When electrically Neutral, it will also have 78 electrons.
The most common isotope will have 195-78 = 117 neutrons.
78
Platinum has an atomic number of 78. Thus, neutral platinum will have 78 protons and 78 electrons to balance it out. Platinum's three most common isotopes are 194Pt, 195Pt, and 196Pt, having 116, 117, and 118 neutrons, respectively.
It has 195-78=117 neutrons. (mass no. - no. of protons)
117 neutrons.
platinum has 78 protons, 78 electrons,and 117 neutrons
The atomic number of platinum is 78. So there are 78 protons.
The number of neutron depends on the isotope. Pt-195 will have 117 neutrons (195 - 78 - 117)
Platinum has 117 neutrons
An estimated 117 neutrons. This can vary as platinum has different isotopes of different mass thus resulting in varying number of neutrons.
11 neutrons
There are 77 Neutrons in the nucleus of one atom of Xenon
how many protons an d neutrons are in vanadium
A stable magnesium atom has 12, 13 or 14 neutrons. The atom with 12 neutrons is the most common one.
117 neutrons in Pt-195 isotope.
The neutrons are located in the nucleus in any atom.
platinum
An estimated 117 neutrons. This can vary as platinum has different isotopes of different mass thus resulting in varying number of neutrons.
Each isotope has another number of neutrons.Number of neutrons = Mass number of an isotope – 78
A typical atom of iodine contains 74 neutrons.
11 neutrons
45 neutrons
It depends it can be protons of neutrons depending on which atom but for many it is neutrons
There are 19 neutrons in a 36Cl atom.
The atomic weight minus the number of protons = the atom's neutrons.
52 neutrons.
