Answer 2

Examples of substances containing Fluorine with different types of bonds:

A) Covalent nonpolar bond: One example of a substance that contains a covalent nonpolar bond with Fluorine is carbon tetrafluoride (CF4). In CF4, each carbon atom is bonded to four fluorine atoms through covalent bonds, and the bond between carbon and fluorine is nonpolar [[1]].

B) Covalent polar bond: An example of a substance that contains a covalent polar bond with Fluorine is hydrogen fluoride (HF). In HF, the hydrogen atom is bonded to the fluorine atom through a covalent bond, and the bond between hydrogen and fluorine is polar [[2]].

C) Ionic bond: An example of a substance that contains an ionic bond with Fluorine is sodium fluoride (NaF). In NaF, the sodium atom donates an electron to the fluorine atom, resulting in the formation of an ionic bond between them [[3]].

Comparison of the structure of Na+ and O2- ions with the structure of a Neon atom:

The structure of Na+ ion: Sodium (Na) loses one electron to achieve a stable electron configuration, resulting in the formation of a Na+ ion. The Na+ ion has a noble gas configuration similar to Neon (Ne) with a completely filled outer electron shell. However, the Na+ ion has 11 protons in its nucleus, while Neon has 10 protons [[4]].

The structure of O2- ion: Oxygen (O) gains two electrons to achieve a stable electron configuration, resulting in the formation of an O2- ion. The O2- ion has a noble gas configuration similar to Neon (Ne) with a completely filled outer electron shell. However, the O2- ion has 8 protons in its nucleus, while Neon has 10 protons [[5]].

Similarities between Na+, O2- ions, and Neon atom: - All three have a completely filled outer electron shell, which gives them greater stability. - They have similar electron configurations, resembling the electron configuration of a noble gas.

Differences between Na+, O2- ions, and Neon atom: - Na+ and O2- ions have a different number of protons in their nucleus compared to Neon. - Na+ and O2- ions have a different number of electrons compared to Neon. - Na+ and O2- ions have a positive and negative charge, respectively, while Neon is neutral.
