What is metallic bonding , properties and everything about it?

The particles in a metal are held together by metallic bonds.

Metallic bonds are strong and a lot of energy is needed to break them. This is why metals have high melting points and boiling points.

Metals contain electrons that are free to move in the metal structure, carrying charge from place to place and allowing metals to conduct electricity well.

Metallic bonding is the strong attraction between closely packed positive metal ions and a 'sea' of delocalised electrons.

mass molar of  gas (Mw):

Mw = 107 g/mol

Explanation:

∴ m gas = 3.82 g

∴ V gas = 0.854 L

∴ T = 302 K

∴ P = 1.04 atm

ideal gas:

∴ n = m / Mw

⇒ PV = RTm/Mw

⇒ Mw = RTm / PV

⇒ Mw = ((0.082 atm.L/K.mol)*(302 K)*(3.82 g)) / ((1.04 atm)*(0.854 L)

⇒ Mw = 106.51 g/mol ≅ 107 g/mol
