Set of 4 numbers which give complete information of atom ??

0Thank You

Amar Kumar 8 years, 1 month ago

Quantum numbers are a set of values that describes the state of an electron including its distance from the nucleus, the orientation and type of orbital where it is likely to be found, and its spin.

The Pauli exclusion principle states that no two electrons in an atom can have the same set of quantum numbers.

The principle quantum number (n) is the number of the electron's shell.
The angular momentum quantum number (l) is the type of orbital (s=0, p=1, etc).
The magnetic quantum number (ml) is the orientation of the orbital (integers from –l to l, for p = -1, 0, 1).
The spin projection quantum number (ms) is the spin of the electron (either -½ or ½).

Syamala Devi Nukella 8 years, 1 month ago

Bond enthalpy (also known as bond energy) is defined as the amount of energy required to break one mole of the stated bond. For example, the bond energy of a O-H single bond is 463 kJ/mol. This means that it requires 463 kJ of energy to break one mole of O-H bonds.
