Halogens are noble gasses, located on the far left of the periodic table. They are used partly for lighting, and are of great importance to scientists because they don't "mingle" easily with other elements.
To the top. Common knowledge my dude. Heat always rises to the top.
The answer is 28.02.
The chemical formula for cadmium nitrate is Cd(NO₃)₂.
There are in total 2 nitrogen atoms in Cd(NO₃)₂. If <span>the atomic weight of nitrogen is 14.01</span>, the mass <span>of two nitrogen atoms in one mole of cadmium nitrate is 28.02:
2 </span>· 14.01 = 28.02
That force is electric force of attraction.
