Only one. There is a quick way to establish how many covalent bonds any element forms. The number of covalent bonds equals eight minus the group number of the particular element.
Example: Carbon - (group 4) 8-4=4
Nitrogen - (group 5) 8-5=3
Chlorine - (group 7) 8-7=1
only 1 bond when reacting to metals and hydrogen(oxidation value -1).
Cl is in the 7th row of the Periodic Table.
It has 7 electrons in its outer shell.
It has strong attraction for 1 electron.
Having 8 electrons (octet) makes the Cl ion very stable.
The shell can only hole 8 electrons .

However:
Reacting to oxygen it can have oxidation values of +1 (hypochlorite), +3 (chlorite), +5 (chlorate) or even +7 (perchlorate)

Chlorine can form one bond, as it has seven valence electrons and requires one more electron to complete its octet. This allows chlorine to typically form one covalent bond with another atom.
No, oxygen and chlorine do not typically form an ionic bond. They are more likely to form covalent bonds, where they share electrons rather than transferring them.
Both calcium and chlorine can form ionic bonds with each other due to calcium's tendency to lose electrons and chlorine's tendency to gain electrons, similar to hydrogen and nitrogen which can form covalent bonds by sharing electrons. In both cases, the bonds formed involve the sharing or transfer of electrons to achieve a stable electron configuration.
No, oxygen and chlorine are not ionic compounds. Oxygen and chlorine are nonmetals and tend to form covalent bonds rather than ionic bonds. In covalent bonds, atoms share electrons, while in ionic bonds, one atom transfers electrons to another.
Chlorine typically forms one bond with other elements, as it has seven electrons in its outer shell and can gain one more electron to achieve a full outer shell, forming a single bond.
A silicon atom does not typically form covalent bonds with chlorine atoms. Silicon is more likely to form bonds with oxygen atoms to create silicon dioxide (SiO2) or silicates. These compounds are stable due to the strong bonds formed between silicon and oxygen atoms.
