Answer:
Hund's rule
Explanation:
Hund's rule states that for an atom in the ground state, the number of unpaired electrons is the maximum possible and these unpaired electrons have the same spin.
I will clearly illustrate this using the ground state of the nitrogen atom. Nitrogen atom contains seven electrons. Its electronic configuration is; 1s2 2s2 2px1 2py1 2pz1.
Notice that the number of unpaired electrons in this configuration is maximum and they are all expected to possess the same spin in accordance with Hund's rule

Answer:
6.94 × 10^33Hz
Explanation:
E = hf
Where;
E = Energy of wave (J)
h = Planck's constant (6.626 × 10^-34J/s)
f = frequency (Hz)
According to the information provided in this question, the hypothetical energy of the wave is 4.6J
Hence, using E = hf
4.6 = 6.626 × 10^-34 × f
f = 4.6 / 6.626 × 10^-34
f = 0.694 × 10^34
f = 6.94 × 10^33Hz
Answer:
Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. ... Water molecules have a polar arrangement of oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge
