Question

how some atoms bond
explain what is happening in this picture in
your own words.
what is the classification/type of atom is atom 1? atom 2?
therefore, this picture must show the process for which type of bonding? explain.

Explanation:

• For the first part: The lithium atom (atom 1) has an extra electron in its outer - shell. It donates this electron to the fluorine atom (atom 2). The fluorine atom, which has an incomplete outer - shell (needs one more electron to complete its octet), accepts the electron.
• For the classification: Atom 1 (lithium) is a metal atom. Metals tend to lose electrons. Atom 2 (fluorine) is a non - metal atom. Non - metals tend to gain electrons.
• For the bonding type: This is ionic bonding. Ionic bonding occurs when there is a transfer of electrons from a metal atom (which forms a cation) to a non - metal atom (which forms an anion). The electrostatic attraction between the cation (Li⁺) and anion (F⁻) holds the compound (LiF) together.

Answer:

• First part: Lithium donates an electron to fluorine to complete fluorine's outer - shell.
• Classification: Atom 1 (Li) is a metal atom; Atom 2 (F) is a non - metal atom.
• Bonding type: Ionic bonding (due to electron transfer from metal to non - metal).
