Explain the trend in boiling parts of the halogen

Chemistry
1 answer:
Svetlanka [38]3 years ago
8 0

Answer:

The boiling point of the halogens increases as you go down the group. The halogens exist as diatomic molecules, with both atoms sharing an electron to completely fill the outer shell. The increase in boiling (and melting point) can be attributed to the increase in intermolecular forces (van der Waals).tion:

What happens when energy is removed from liquid water
mariarad [96]

Answer:

When energy is removed in liquid water then it will solidify since heat is given off by the system to its surrounding. It is an exothermic process where the enthalpy decreases since heat is taken off. So liquid water becomes ice in an exothermic process.

In the quantum theory, the magnetic orbital momentum quantum number is most directly associated with which property of orbitals?
kolezko [41]

Answer: In the quantum theory, the magnetic orbital momentum quantum number is most directly associated with orientation of orbitals

In the quantum theory, angular orbital momentum quantum number is most directly associated with shape of orbitals.

Explanation:

Principle Quantum Number : It describes the size of the orbital and the energy level. It is represented by n. Where, n = 1,2,3,4....

Angular orbital momentum quantum number or Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as m_l. The value of this quantum number ranges from (-l\text{ to }+l). When l = 2, the value of m_l will be -2, -1, 0, +1, +2.

Spin Quantum number : It describes the direction of electron spin. This is represented as m_s The value of this is +\frac{1}{2} for upward spin and -\frac{1}{2} for downward spin.
