Compare a mole of Ag-108 and a mole of Pt-195 using atoms, protons, electrons, and neutrons.
47Ag108
47 protons, 47 electrons, 108-47 neutrons.
Pt is done the same way.
Since they both contain one mole, you have
6.02 x 10^
23
particles of silver and 6.02 x 10^
23
particles of platinum. The difference would be in
the number of protons, neutrons, and electrons
present because silver contains 47 protons per
atom, 47 electrons per atom and 61 neutrons per
atom, while platinum contains 78 protons per
atom, 78 electrons per atom and 117 neutrons per
atom. A mole of platinum would contain more
protons, electrons and neutrons but the same
number of atoms
A mole is a unit of measurement in chemistry that represents Avogadro's number, which is approximately 6.022 x 10^23. It is used to express the amount of a substance.
Ag-108 and Pt-195 are isotopes of silver (Ag) and platinum (Pt), respectively. To compare a mole of Ag-108 and a mole of Pt-195, we need to consider the number of atoms, protons, electrons, and neutrons in each.
1. Atoms:
In one mole of any substance, there are Avogadro's number of atoms. Hence, both a mole of Ag-108 and a mole of Pt-195 will contain the same number of atoms, which is approximately 6.022 x 10^23.
2. Protons:
Ag-108 has 47 protons because the atomic number of silver is 47. Pt-195 has 78 protons because the atomic number of platinum is 78. Since the number of protons is determined by the atomic number, the number of protons in a mole of Ag-108 and a mole of Pt-195 will remain constant, regardless of the amount.
3. Electrons:
The number of electrons in an atom is equal to the number of protons in a neutral atom. Therefore, a mole of Ag-108 will have 47 x 6.022 x 10^23 electrons, and a mole of Pt-195 will have 78 x 6.022 x 10^23 electrons.
4. Neutrons:
To determine the number of neutrons in an isotope, subtract the atomic number from the mass number. Ag-108 has a mass number of 108, so it will have 108 - 47 = 61 neutrons. Pt-195 has a mass number of 195, so it will have 195 - 78 = 117 neutrons. The number of neutrons in a mole of Ag-108 and a mole of Pt-195 will remain constant, regardless of the amount.
In summary, a mole of Ag-108 and a mole of Pt-195 will have the same number of atoms, but their number of protons, electrons, and neutrons will depend on their respective atomic numbers and mass numbers.
To compare a mole of Ag-108 and a mole of Pt-195, we need to consider the number of atoms, protons, electrons, and neutrons in each of these isotopes.
First, let's understand what a mole is. A mole is a unit of measurement used in chemistry that represents a specific quantity of a substance. One mole of any substance contains 6.022 × 10^23 particles, which is called Avogadro's number.
Now, let's compare a mole of Ag-108 and a mole of Pt-195 in terms of atoms, protons, electrons, and neutrons:
1. Atoms: Since one mole of any substance contains Avogadro's number of particles, a mole of Ag-108 consists of 6.022 × 10^23 atoms of Ag-108, while a mole of Pt-195 consists of 6.022 × 10^23 atoms of Pt-195. So, both will have the same number of atoms.
2. Protons: The atomic number of an element represents the number of protons in its nucleus. Ag-108 is silver with an atomic number of 47, so it has 47 protons. Pt-195 is platinum with an atomic number of 78, so it has 78 protons. Therefore, a mole of Ag-108 contains 47 × 6.022 × 10^23 protons, and a mole of Pt-195 contains 78 × 6.022 × 10^23 protons.
3. Electrons: In neutral atoms, the number of electrons is equal to the number of protons. So, a mole of Ag-108 contains 47 × 6.022 × 10^23 electrons, and a mole of Pt-195 contains 78 × 6.022 × 10^23 electrons.
4. Neutrons: To determine the number of neutrons in an isotope, we subtract the atomic number (proton number) from the mass number (number of protons + neutrons). Ag-108 has a mass number of 108, so it has 108 - 47 = 61 neutrons. Pt-195 has a mass number of 195, so it has 195 - 78 = 117 neutrons. Thus, a mole of Ag-108 contains 61 × 6.022 × 10^23 neutrons, and a mole of Pt-195 contains 117 × 6.022 × 10^23 neutrons.
In summary, a mole of Ag-108 and a mole of Pt-195 have the same number of atoms (6.022 × 10^23). However, they differ in the number of protons, electrons, and neutrons based on their atomic numbers and mass numbers.
