Did u mean mass of potassium nitrate or the mass of nitrogen in potassium nitrate
Answer: the correct option is A (C.N. = 6; O.N. = +4.)
Explanation:In the coordination
compound[Cr(NH3)(en)2Cl]Br2,
the coordination number (C.N.) and oxidation number (O.N.) of the
metal atom are 6 and +4 respectively.
Answer:
Subscripts are small numbers right next to the letters
a) 3p⁴/3
Do you mean atomic number 16 (sulfur)?
Its electron configuration is <em>1s² 2s²2p⁶ 3s² 3p⁴</em>.
Thus, a neutral sulfur atom will have a terminal electronic configuration = 3p⁴ and the orbital diagram of its terminal electronic configuration will have 3 orbitals (see the image be
low).
