No, Group 6 and Group 7 elements can form a variety of bonds, including covalent, ionic, and metallic bonds. The tendency to form covalent bonds increases as you move across the period from Group 1 to Group 7. Group 6 elements, such as oxygen and sulfur, commonly form covalent bonds, while Group 7 elements, such as chlorine and fluorine, tend to form ionic bonds with metals.
You can determine the number of covalent bonds an element can form by looking at its group number on the periodic table. Elements in group 4 can typically form 4 covalent bonds, elements in group 5 can form 3 bonds, elements in group 6 can form 2 bonds, and elements in group 7 can form 1 bond.
Group 4A elements have 4 valence electrons, which allows them to form strong covalent bonds by sharing electrons with other atoms. This sharing of electrons helps them achieve a full outer electron shell, making them more stable. Additionally, group 4A elements are not as electronegative as elements in other groups, making them more likely to form covalent bonds instead of ionic bonds.
All non-metals in group IV will be able to form 4 covalent bonds with other elements. They need 4 more electrons to form the octet structure in their valence shell. Hence, they can form 4 single covalent bonds to constitute the covalent structure. On the other hand, elements in group III, such as boron, can also make 1 double bond and 3 single bonds to share 5 electrons to achieve octet structure.
A molecule is a neutral group of atoms joined by one or more covalent bonds. Covalent bonds are formed when atoms share electrons to achieve stability. Examples include oxygen gas (O2) and water (H2O).

Elements such as hydrogen (H), nitrogen (N), oxygen (O), fluorine (F), chlorine (Cl), bromine (Br), and iodine (I) can form diatomic molecules joined by single covalent bonds. For example, H2, N2, O2, F2, Cl2, Br2, and I2.
Group 17 elements need one more electron to achieve the nearest noble gas electronic configuration. Hydrogen also needs one electron. Hence hydrogen behaves like a group 17 element when forming covalent bond.
Group-14 elements share electrons. they form covalent bonds.
4
Elements in group 17 need one electron to gain a stable electron configuration. Two atoms of the same element or two elements in this family forms compounds with a single covalent bond. Examples are chlorine, bromine or iodine chloride.
Noble gases, such as helium, neon, and argon, do not typically form covalent bonds as they have a full outer shell of electrons, making them stable and non-reactive.
So basically covalent starts with a c just like the group carbon does on the periodic table, thus, group 14 form covalent bonds. That's how I always remember it. While on the other hand group 1 and 17 form ionic bonds.
