Silver atoms contain 47 protons, while gold atoms contain 79 protons. They also have different number of neutrons depending on the isotope. The number of electrons in an atom is equal to its number of protons if the atom has no electric charge.
47 centimeters = 18.5 inches
Titanium-47 has 25 neutrons.
The mass of the moon, according to a quick Google search is 7.36 x 10^22 kg. Times this by 1000, and you get your answer in grams, which are better to work with. The molar mass of lead is 207.2 grams. So, (7.36 x 10^25)/207.2 = 3.552123552 x 10^23 moles of Pb. Now, multiplying by Avogadro's constant (6.0221415 x10^23) will give you your answer, which is 2.139139065 x 10^47, which is a huge number!!! Anways, hope that helped.
it has 47 protons because the atomic number is the same thing as the number of protons
4.005
All germanium atoms have 32 electrons.
To find the number of moles in 47.0 grams of Ag (silver), divide the mass given by the molar mass of silver (107.87 g/mol). [ \text{Number of moles} = \frac{47.0 , \text{g}}{107.87 , \text{g/mol}} \approx 0.436 , \text{moles} ]
Silver is an element, pure silver would contain only silver atoms.
I assume you mean 3.55 grams of silver. Don't forget your units! Silver (Ag, #47) has an atomic mass of about 108 grams per mole. Set up a direct proportion: 108/1=3.55/x, where x is the unknown number of moles in 3.55 grams Ag. Solve for x to get approx. 0.033 moles Ag. Multiply this number by Avogadro's constant of 6.02x1023 to get the number of representative particles. So, 0.033(6.02x1023)=1.99x1022 atoms of silver.
The term silver-96 indicates a mass number of 96 for that isotope of silver. The mass number of an isotope is the sum of protons and neutrons in the nuclei of its atoms. On the periodic table, the atomic number for silver is 47. The atomic number of an element is the number of protons in the nuclei of its atoms. The difference between the mass number and atomic number is the number of neutrons in the nuclei of the atoms of that isotope. In a neutral atom, the number of protons and electrons are equal. Therefore, silver-96 has 47 protons and 47 electrons in its atoms. The number of neutrons = 96 - 47 = 49.
There are a total of 3 silver atoms in Ag3. Since each silver atom has 47 electrons, the total number of electrons in Ag3 would be 3 * 47 = 141 electrons.
