Copper has 29 electrons, and its electron configuration is:
1s2 2s2 2p6 3s2 3p6 3d10 4s1.
Therefore, copper has 1 valence electron.
Hope this helps~
Answer:
it changes.
Explanation:
when in solid form it has an amount of mass. but when evaporated, water is pretty much massless.
Answer:
The value is
Explanation:
From the question we are told that
The equilibrium spacing is
The mass of a hydrogen atom is
The principal quantum number of the second energy level is
The principal quantum number of the first energy level is
Given that the hydrogen molecule is a symmetrical diatomic molecule, its moment of inertia is mathematically represented as
Generally for rotational spectrum the energy level is mathematically represented as
Generally the energy difference between the first energy level and the second energy level is mathematically represented as
=>
=>
substituting for I
=>
Generally this difference in energy level can also be mathematically represented as
=>
=>
Here h is Planck's constant with value
and c is the speed of light with value
So
=>
=>
=>
Fossil Fuels give off energy when they are burned
One valuable fossil fuel is natural gas. It is a cleaner-burning fuel source.
