Answer:
They represent the valence electrons, so s and p sublevels only! This does not include the d block!
Explanation:
Internal energy is the sum of all the energies inside or within a system because molecules of the system will have kinetic, potential, rotational, vibrational etc energies.
Internal energy arises because of random or disordered movement of particles within a system.
Therefore, internal energy of a system is the sum of kinetic and potential energy of all the particles present inside the system.
The variable for internal energy is "U". Also, change in internal energy is represented by .
Answer:
Explanation:
Dear student, there is no sufficient information to calculate the empirical formula but we will explain what Empirical Formula is all about.
An empirical formula is made up of symbols that denote the elements in a complex, such as H for hydrogen and O for oxygen, as well as subscripts that indicate the number of atoms from each constituent element.
The empirical formula is the atoms in a complex with the lowest whole number ratio. The precise number of atoms in a single molecule is not necessarily shown.
