Column tells you how many valence electrons there are
Row tells you how many layers (circles)
Sodium (Na) has 1 valence electron
Sodium (Na) is the 3rd row so there's 3 circles
Has 11 total electrons
Bohr models show ALL ELECTRONS
The first shell can only hold 2 electrons
Every shell after that can hold 8.
So the first shell has 2 electrons, second one has 8 electrons, and the third one has 1.
2 + 8 + 1 = 11
When pressure in a chemical reaction increases, the equilibrium will shift towards the side of the reaction with fewer moles of gas. When there is a decrease in pressure, the equilibrium will shift towards the side of the reaction with more moles of gas.Therefore; in this case; increased the Equilibrium will shift to the left and favor the reverse reaction. This is because the side of products has more moles compared to the side of reactants, thus increased in pressure will aid conversion of products to reactants.

Earth's atmosphere refracts sunlight toward the moon when the moon passes through the umbra. The atmosphere scatters blue light from the sun, but red light is refracted and bent toward the moon.
