When Water freezes or begin to freeze, it molecules start to slow down enough that their attraction arrange into one shape till they melt again.
Goods are objects that fulfill peoples needs and wants.
Answer:
The energy difference between these 2p and 2s orbitals is 
Explanation:
Wavelength of the photon emitted = 
Energy of the photon will corresponds to the energy difference between 2p and 2s orbital = E
Energy of the photon is given by Planck's equation:

h = Planck's constant = 
c = Speed of the light = 


The energy difference between these 2p and 2s orbitals is 
Answer:
true
Explanation:
because if you find the right answer that proves the theory to be correct.
Answer:
B.They do not react chemically
Explanation:
This is because all noble gases haves full outer shell therefore they don’t participate in bonding.They are referred to as inert which means unreactive.
