Answer 2

Elements Li and N

The elements Li and N refer to lithium and nitrogen, respectively.

Lithium (Li) is a chemical element with the atomic number 3 and the symbol Li. It is a soft, silvery-white alkali metal that belongs to Group 1 of the periodic table. Lithium is the lightest metal and has a low density. It is highly reactive and can easily lose its one valence electron to form a positive ion. Lithium is commonly used in rechargeable batteries, ceramics, glass, and as a medication for certain mental health conditions.

Nitrogen (N) is a chemical element with the atomic number 7 and the symbol N. It is a colorless, odorless, and tasteless gas that makes up about 78% of the Earth's atmosphere. Nitrogen is a nonmetal and belongs to Group 15 of the periodic table. It has five valence electrons and can form various compounds, including ammonia (NH3) and nitric acid (HNO3). Nitrogen is essential for life as it is a key component of proteins and nucleic acids.

In summary, lithium (Li) is a soft, silvery-white metal, while nitrogen (N) is a colorless gas. Both elements have distinct properties and play important roles in various applications and natural processes.
