Question

4. In what period can you find Nitrogen on the periodic table?

Answer 1

Nitrogen is located in the second period of the periodic table, where it is categorized as a nonmetal and can form nitride ions as an anion.

Step-by-step explanation:

Nitrogen can be found in the second period of the periodic table. This is because periods are the horizontal rows on the periodic table and nitrogen, which has an atomic number of 7, is located in the second row. Due to its position in Group 15, it is considered a nonmetal and can gain three electrons to form the nitride ion (N³-), behaving as an anion. This property is significant when considering reactions with metals that can reduce nitrogen to form metal nitrides, and in the formation of nitrogen oxides and hydrides.

Answer 2

The second period contains the elements lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon. In a quantum mechanical description of atomic structure, this period corresponds to the filling of the second (n = 2) shell, more specifically its 2s and 2p subshells.
