What is the electron structure of nitrogen?
2 answers:
Answer : The correct option is,
Explanation :
Electronic configuration : It is defined as the arrangement of the electrons of an atom in an atomic orbital.
The given element is, nitrogen.
The nitrogen element belongs to group 15 and the atomic number of nitrogen is 7.
As we know that the number of electrons is equal to the number of atomic number.
The number of electrons present in nitrogen = 7
Thus, the electronic configuration of nitrogen is,

Answer:
The rain falling in New England is 2.29 times more acidic than the one in the American Midwest.
Explanation:
The acidity of a solution depends on the concentration of H⁺ ions ([H⁺]). We can calculate this concentration from the pH using the following expression.
pH = -log ([H⁺])
American Midwest
pH = -log ([H⁺])
5.02 = -log ([H⁺])
[H⁺] = antilog (-5.02) = 9.55 × 10⁻⁶ M
New England
pH = -log ([H⁺])
4.66 = -log ([H⁺])
[H⁺] = antilog (-4.66) = 2.19 × 10⁻⁵ M
The ratio of concentrations is:
The rain falling in New England is 2.29 times more acidic than the one in the American Midwest.
