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.
Boron has 5 neutrons and 5 protons for its most common isotope
Boron has 5 neutrons and 5 protons for its most common isotope
6 protons. The number of neutrons varies, but the most common isotope has 6 neutrons.
This question is impossible to answer properly without knowing either how many protons there are or how many neutrons there are or how many electrons there are along with the charge. However it is most likely nitrogen, because Nitrogen's most common isotope is 14.
Chlorine has the atomic number of 17. To keep it neutral then, it must have 17 protons and 17 electrons. Chlorine's most common isotope is 35Cl. That means it has 35 - 17 = 18 neutrons.
Sodium's most common isotope is sodium-23, which has 11 protons and 12 neutrons.
Protons: 6 Neutrons: Anywhere between 2 and 16. The most common isotope of carbon has 6 neutrons.
Nickel have 28 protons and electrons and a different number of neutrons for each isotope..
Phosphorus-31 is the most common isotope. (Wikipedia)
In europium, the number of protons is 63, electrons is also 63, and neutrons can vary based on the isotope of europium. The most common isotope, europium-153, has 90 neutrons.
Protons-68 Electrons-68 Neutrons-About 99
The most common isotope of actinium, Ac-227, has 89 protons and 138 neutrons.
