Answer 2

Ordering the Elements Li, F, N, Be, O, B, C by Properties

To order the elements Li, F, N, Be, O, B, C by properties, we need to consider various factors such as atomic number, atomic mass, electronegativity, and chemical reactivity. Let's analyze these elements based on their properties:

1. Lithium (Li): - Atomic number: 3 - Atomic mass: 6.94 g/mol - Electronegativity: 0.98 - Reactivity: Lithium is a highly reactive metal. It readily loses its outermost electron to form a positive ion. - Based on its low atomic number and reactivity, lithium is the first element in the list.

2. Fluorine (F): - Atomic number: 9 - Atomic mass: 18.998 g/mol - Electronegativity: 3.98 - Reactivity: Fluorine is the most electronegative element and highly reactive. It readily gains an electron to achieve a stable electron configuration. - Based on its high electronegativity and reactivity, fluorine is the second element in the list.

3. Nitrogen (N): - Atomic number: 7 - Atomic mass: 14.007 g/mol - Electronegativity: 3.04 - Reactivity: Nitrogen is a nonmetal and relatively unreactive under normal conditions. It forms stable diatomic molecules (N₂) and is an essential component of many organic and inorganic compounds. - Based on its atomic number and relatively lower reactivity compared to lithium and fluorine, nitrogen is the third element in the list.

4. Beryllium (Be): - Atomic number: 4 - Atomic mass: 9.012 g/mol - Electronegativity: 1.57 - Reactivity: Beryllium is a relatively reactive alkaline earth metal. It readily loses two electrons to form a positive ion. - Based on its atomic number and reactivity, beryllium is the fourth element in the list.

5. Oxygen (O): - Atomic number: 8 - Atomic mass: 15.999 g/mol - Electronegativity: 3.44 - Reactivity: Oxygen is a highly reactive nonmetal. It readily gains two electrons to achieve a stable electron configuration. It is involved in many chemical reactions and is essential for supporting life. - Based on its atomic number and reactivity, oxygen is the fifth element in the list.

6. Boron (B): - Atomic number: 5 - Atomic mass: 10.81 g/mol - Electronegativity: 2.04 - Reactivity: Boron is a metalloid and relatively unreactive under normal conditions. It forms stable covalent compounds and is used in various applications, including electronics and materials. - Based on its atomic number and relatively lower reactivity compared to beryllium and oxygen, boron is the sixth element in the list.

7. Carbon (C): - Atomic number: 6 - Atomic mass: 12.01 g/mol - Electronegativity: 2.55 - Reactivity: Carbon is a nonmetal and forms the basis of organic chemistry. It can form stable covalent bonds with other elements, including itself, to create a wide variety of compounds. - Based on its atomic number and reactivity, carbon is the seventh element in the list.

Therefore, the elements Li, F, N, Be, O, B, C can be ordered by properties as follows:

Li < F < N < Be < O < B < C

Please note that this ordering is based on the properties mentioned above and may vary depending on the specific properties considered or the context in which the elements are being compared.
