How many protons are found in an atom of platinum (Pt)?
An atom of platinum (Pt) has 78 protons.
Which has more protons gold or platinum?
Gold
How many protons are in platinum?
Platinum's Atomic number is 78 . The Atomic number is the same as the number of protons in an atom of that element.
How many protons does a star have?
This depends directly upon the mass of the star, and to a smaller extent, composition. Let's use the Sun, for example It masses 1.989e+30 kg, or 1,989,000,000,000,000,000,000,000,000,000 kg. About 90% of the Sun's mass is protons (in the form of Hydrogen.). There is some Helium, Oxygen and other elements in the Sun, but on average, these only make up about 20% of the Sun's mass and they are just under 50% protons. Assuming 90% protons, the Sun then contains 1.79e+30 kg of protons. Weight of protons = 1 gram per mole (a mole = 6.02e+23), So, the sun has about 1.0775e+57 protons. In longhand, that's 1,077,500,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 This number is pronounced 1.0775 Octodecillion. I didn't make this name up - see http://en.wikipedia.org/wiki/Octodecillion
What is the total number of protons if a sample of scandium has a mass of 7.9027?
Interesting question! Let us proceed slowly. Scandium has 21 protons per atom and 6.022 X 10^23 atoms per mole. 21 X 6.022 X 10^23 = 1.26 X 10^25 protons per mole of Scandium. 7.9027 grams Scandium (1mol/44.96g ) = 0.176 mol Scandium 0.176 mole Scandium X 1.26 X 10^25 protons Scandium = 2.22 X 10^24 total protons in 7.9027 grams of Scandium. ( you can put this all into one conversion string if you like )
How many protons are found in an atom of platinum (Pt)?
An atom of platinum (Pt) has 78 protons.
How many protons are found in Platinum 197?
78 protons, 78 electrons and 119 neutrons
In 1 mole of NO2 gas how many protons are there?
N has 7 protons O has 8 protons (O2 therefore 16) So 1 molecule of NO2 gas has 7 + 16 = 23 protons 1 mole of NO2 gas (6.022 * 1023 molecules) have 138.506 * 1023 protons.
How many protons are in 4.78g of K?
4.78 grams K (1 mole K/39.10 grams)(6.022 X 1023/1 mole K)(19 protons/1 atom K) = 1.40 X 1024 protons in that mass potassium ============================
Which has more protons gold or platinum?
Gold
How many protons are there in 134 grams of iron III hydrogen phosphate?
Fe2(HPO4)3Four different species! Will need number atoms every species as protons vary. What a lot of work! In order.134 grams Fe2(HPO4)3 (1 mole Fe2(HPO4)3/399.634 grams)(2 mole Fe/1 mole Fe2(HPO4)3)(6.022 X 1023/1 mole Fe)= 4.04 X 1023 atoms iron * 26 protons = 1.05 X 1025 protons iron-----------------------------------------------------======================-----------------------------------------------==============134 grams Fe2(HPO4)3/399.634 grams)(12 mole O/1 mole Fe2(HPO4)3)(6.022 X 1023/1 mole O)= 2.42 X 1024 atoms oxygen * 8 protons = 1.94 X 1025 protons oxygen--------------------------------------------------------====================I think you can add all the bold numbers to get total.
Is an atom with 78 protons in its nucleus a palladium atom?
No. It would be platinum if it has 78 protons.
How many protons neutrons and electrons does platanium have?
Platinum has 78 of each. Plutonium has 94 of each. There is no "platanium".
What the mass of a proton of a mole of sodium?
Mass of one proton = 1.67 X 10 -27 kgA mole of sodium atoms = 6.022 X 1023 atoms11 protons per sodium atom11 * 6.022 X 1023= 6.62 X 1024 protons per mole sodium==================================so,6.62 X 1024 * 1.67 X 10 -27 kg= 0.011 kilograms of protons in mole sodium====================================( 11 grams of protons)
How many electrons are in platinum?
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.
An element that is a precious metal with 78 protons?
Platinum.
What is the most common isotope of Pt has how many protons?
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.
