silver?
To find the mole fraction of silver in the mixture, divide the moles of silver by the total moles of both elements.
To find the mole fraction of silver in the mixture, we need to calculate the moles of silver and iron. First, calculate the moles of silver by dividing the mass of silver by its molar mass. Then, calculate the moles of iron in the same way. Finally, find the mole fraction of silver by dividing the moles of silver by the total moles of both elements in the mixture.
Moles of silver = mass of silver / molar mass of silver
Moles of iron = mass of iron / molar mass of iron
Mole fraction of silver = moles of silver / (moles of silver + moles of iron)

Iron atoms all have 26 protons, however Fe²⁺ and Fe³⁺ only have 24 and 23 electrons, respectively, and elemental uncharged Fe contains 26 electrons.
The elementary electric charge of the electron is a negative one, making it a subatomic particle. Due to their lack of components or substructure, electrons, which are members of the lepton particle family's first generation, are typically regarded to be elementary particles.
After the 4s orbitals are full, they fill the 3d orbitals. However, when they are ionized, their electrons only fill the ground state 3d orbitals. Iron (II) ion will thus contain four unpaired electrons.
Quarks make up protons and neutrons, but not electrons. We believe that quarks and electrons are basic particles that are not composed of lesser subatomic particles.
Thus, option 2 is correct.

Answer:
The correct answer is A.
Explanation:
The periodic table published by Mendeleev in 1869 was the first periodic table to group the elements. Based on the hypothesis that the properties of the elements are a periodic function of their atomic weights, he placed in the table all the elements known up to that moment, which became 63 elements, ordering them in such a way that the elements belonging to the same family appear in the same vertical line. The elements were arranged in the increasing order of their atomic masses.

Metals experience plastic deformation when a specific amount of pressure and temperature is applied to them. Most metals have low specific heat. Because of their low specific heat, they easily get hot when heat is applied to them.
