The ionization enthalpy of an atom depends on the number of electrons and protons (nuclear charge) of that atom. Now, the isotopes of an element have the same number of protons and electrons. Therefore, the first ionization enthalpy for two isotopes of the same element should be the same.
Calcium (Ca) and strontium (Sr) are expected to show chemical reactions similar to magnesium (Mg). This is because the number of valence electrons (2) is same in all these three...
(i) During the process of ionization, the electron to be removed from beryllium atom is a 2s-electron, whereas the electron to be removed from boron atom is a 2p-electron.
Now, 2s-electrons...
(i) Atomic number
The atomic number of an element is the total number of protons present in the atom of that element. For example, nitrogen has 7 protons in its atom....
Ferromagnetic substances would make better permanent magnets. In solid state, the metal ions of ferromagnetic substances are grouped together into small regions. These regions are called domains and each domain...
Ionization enthalpies are found to increase in the given series due to a continuous filling
of the inner d-orbitals. The irregular variations of ionization enthalpies can be attributed to the extra...
In Mendeleev,'s Periodic Table the two isotopes of chlorine, Cl-35 and Cl-37 would be placed in different slots because the-y have different atomic masses. But because of their similar chemical...
(i) Calpurnia is the speaker of the above lines.
(ii) Calpurnia saw bad omens in her dream regarding Caesar. So, she is worried for him.
(iii) Calpurnia is afraid for Caesar’s life...
