Explanation:
The distribution of electrons of an atom or molecule in an atomic orbital is called electronic configuration.
1. The electronic configuration of Fluorine: [He] 2s²2p⁵.
2. The electronic configuration of Neon: [He]2s²2p⁶
3. The electronic configuration of Sulfur: 1s²2s²2p⁶3s²3p⁴
4. The electronic configuration of Calcium:[Ar] 4s²
5. The electronic configuration of Iron: [Ar] 3d⁶4s²
Hence, this is the required solution.
Answer:
A positive ions is always smaller than the corresponding atom.
A negative ion is always larger than the corresponding atom.
Explanation:
The reason for this is that, when a positive ion is formed, a full shell is usually removed with its electrons thereby reducing the size of the electron cloud and decreasing the size of the electron cloud.
A negative ion is formed by addition of more electrons to the electron cloud hence it spreads out. Interelectronic repulsion accounts for the larger size of the negative ion.
In order for you to get the answer, please have in mind the following situation: To increase the molar concentration of N2O4(g), 2NO2(g) should also increase for equilibrium to occur. Now, this equation is exothermic. By <span>Le Chatelier's principle, equilibrium constant and reaction constants also come into play in terms of increasing or decreasing the temperature. After that I know you can find the answer. </span>
