Lavoisier organized a list of the known
elements of his day as four categories.
Newlands was the first to organize the
elements and show that properties repeated in a periodic way. Mendeleev and Meyer proposed periodic tables showing a relationship between atomic mass and elemental properties. Moseley organized the elements by atomic number instead of atomic mass.
- AC=Hypotenuse=20
- BC=Base=16
AB:-
Apply Pythagorean theorem





Now
- DE=AB/3=12/3=4
- EF=BC/3=16/3=5.3
- DF=AC/3=20/3=6.6
Now



Honestly just try to get 35 questions right, that's about 85%. 30 questions is an F. So goodluck. :)
I just use regular ones cause I don’t like to reuse :)
