Answer:
of silver would be required.
Explanation:
Dimensions of silver mas :
Length = l = 120.0 ft
breadth = b = 60.0 ft
Height = h = 0.33 ft
Volume of silver mass ,V= l × b × h
Density of silver,d =

Answer:
(a) (σ2s)² (σ2*s)² (π2p)⁴ (σ2p)²
(b) (σ2s)² (σ2*s)² (π2p)⁴ (σ2p) (π*2p)
Explanation:
An N atom has five valence electrons, so a molecule of N₂ has 10 valence electrons.
Use the Aufbau Principle to place 10 electrons in the MO diagram for B, C, and N.
1.Ground state
The valence electron configuration of N₂ is
(σ2s)² (σ2*s)² (π2p)⁴ (σ2p)²
2. First excited state
One of the σ2p electrons is promoted to the next higher level, π*2p.
The valence electron configuration becomes
(σ2s)² (σ2*s)² (π2p)⁴ (σ2p) (π*2p)
