please help

Answer 1

Wiki says about Dalton:

The main points of Dalton's atomic theory were:

Elements are made of extremely small particles called atoms.
Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and other properties.
Atoms cannot be subdivided, created, or destroyed.
Atoms of different elements combine in simple whole-number ratios to form chemical compounds.
In chemical reactions, atoms are combined, separated, or rearranged.


p orbital 2*3 = 6

Answer 2

so c and b

Answer 3

Yes, I would go with c and b

Answer 4

whoops, I saw the p but not the px
Only 2 electrons can fit in the p orbital pointing in the x direction. You can also have 2 py electrons and 2 pz electrons.

Answer 5

whoops, I saw the p but not the px
Only 2 electrons can fit in the p orbital pointing in the x direction. You can also have 2 py electrons and 2 pz electrons.

Answer 6

thank you
