Give the formula of the stable fluride by Li, Be, B , C, N, and O. For these fluorides, describes the varition in the bonding that occurs as we move from left to right across the period.
Interpretation:
For each of the elements-
Concept introduction:
- Fluorine forms a variety of chemical compounds but it always adopt an oxidation state of (-1).
- Electronegativity of elements increases as we move from left to right in a period.
- Bonding is generally of two types- ionic and covalent.
In ionic bonding, atoms lose or gain electrons to form ions and these are ions that are bonded through forces of attraction.
In covalent bonding, a covalent bond is formed between the atoms by sharing of valence electrons.

And
As we move from left to right across a periodic table, the bonding shifts from ionic boning to covalent bonding.
Explanation of Solution
Generally,
Metal + non-metal →Ionic compounds
Non-metal +non-metal →Covalent compounds
Thus, Fluorine is a non-metal and it forms ionic compound with a metal (
Therefore, formula for each of the element for the fluorides (

As we move from left to right across a periodic table, the metallic character of the element decreases. Hence, the bonding shifts from ionic boning to covalent bonding as it is not easier to take away the electrons from the non-metals to form ions.
