depends on isotope.
For the most common isotope Platinum-195 (33.5%), there are the following fermions:
Total = 858
Also at any given moment there are an indeterminate number of bosons being interchanged between these 858 fermions to hold the atom together with the electromagnetic, weak, and strong forces:
So even for an atom of one known isotope, the exact number of subatomic particles in it is unknown and cannot be known.
78 protons, 78 electrons and 119 neutrons
Platinum is a rare element too. Atomic number of platinum is 78.
When it has no charge there are 78.the number of electrons is always equal to the number of protons, both are the atomic number. the atomic number of platinum is 78, so 78 electrons and 78 protons too.
There are 78 protons and 78 electrons present in a platinum atom. There are also at least 114 neutrons in the five stable isotopes. 192 Pt = 114 194 Pt = 116 195 Pt = 117 196 Pt = 118 198 Pt = 120
The element platinum (Pt) has 78 protons in the atomic nucleus.
An atom of platinum (Pt) has 78 protons.
78 protons, 78 electrons and 119 neutrons
Gold
Platinum has 78 of each. Plutonium has 94 of each. There is no "platanium".
Platinum is a rare element too. Atomic number of platinum is 78.
One mole of platinum contains Avogadro's number (6.022 x 10^23) of atoms. Since each platinum atom has 78 protons, one mole of platinum contains 78 times Avogadro's number, which equals 4.686 x 10^25 protons.
When it has no charge there are 78.the number of electrons is always equal to the number of protons, both are the atomic number. the atomic number of platinum is 78, so 78 electrons and 78 protons too.
Platinum has 78 of each. Plutonium has 94 of each. There is no "platanium".
Platinum.
All isotopes/ions of Platinum have the same number of protons: 78. If it had a different number of protons, then it would be a completely different element. The only subatomic particles that change in an atom are the electrons and neutrons. The most common isotope of Platinum is 195Pt with 117 neutrons.
If you remove 2 protons and 2 neutrons from gold (Au), the resulting element would be platinum (Pt). Gold has 79 protons and 118 neutrons, while platinum has 77 protons and 116 neutrons.
There are 78 protons and 78 electrons present in a platinum atom. There are also at least 114 neutrons in the five stable isotopes. 192 Pt = 114 194 Pt = 116 195 Pt = 117 196 Pt = 118 198 Pt = 120
