a) Find the electronic configuration of Mo. (2) b) For transition elements, why does the ionization enthalpy tend to increase along the series only slightly as compared to the main group elements?

a) electronic configuration of Mo1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d5 5s1b) The ionization energy increases due to the increase in the nuclear charge with an atomic number at the beginning of the series. Gradually, the shielding effect of the added electrons...

The d-block elements are called transition metals and have valence electrons in d orbitals. The inner transition elements are those who have their last 3 shells incompletely filled. The f...

Chromium (Cr0): [Ar] 3d5 4s1 Free dipositive manganese ion (Mn2+): [Ar] 3d5

Answer: The electronic configuration of chromium is [Ar] 4s1 3d5 Perhaps a mistake in the word "mangnese" and it will be correct manganese The electronic configuration of manganese 2+ is...

The main factors that cause broadening of the spectral line into an absorption band of a molecular solid are the distributions of vibrational and rotational energies of the molecules in...

Due to the increase in the nuclear charge with an atomic number at the beginning of the series. Gradually, the shielding effect of the added electrons also increases. .

I. Integral Enthalpy Of Solution is the heat absorbed or released when a solute is dissolved in a definite amount of solvent. The heat of solution depends on the nature...

The atomic radius of group-16 elements or oxygen family are smaller than that of group-15 elements. This is due to increase in the effective nuclear charge from group-15 elements which...

The more electrons protect the outer electron shell from the nucleus, the less energy is required to extract the electron from the specified atom. The higher the protective effect, the...

The ionization energy refers to the energy required to remove an electron from an ion or a gaseous atom. The first ionization energy refers to the energy utilized in removing...
