If the electronegativity difference between two atoms is less than 1.7, then they form covalent bond.Generally when non metal reacts with another non metal, then a covalent bond is formed between these two atoms.
if a compound is bonded with four other atoms to satisfy its valancy then it is said to be a covalent compound.
Tellurium is an element and will tend to form ionic bonds but can also form covalent bonds. Any element on its own is always nonpolar.
The bond closest in nature to a covalent bond is C-Cl, because carbon and chlorine are both nonmetals, and nonmetals tend to form covalent bonds with each other. The other choices would be closest in nature to an ionic bond because they are all metals bonded with a nonmetal. Metals and nonmetals tend to form ionic bonds with each other.
oxygen normally forms a convalent bond with one or two other oxygen atoms. as well as oxygen atoms forming oxygen molecules, oxygen atoms tend to form bonds with most of the other elements to form oxides. oxygen atoms on there own are rare. as for phosphorous.........
If an element has less than four valence electrons, it will tend to lose its valence electrons and form cations. If an element has more than four valence electrons, it will tend to gain electrons and form anions. An element that has four valence electrons will tend to form covalent bonds rather than ionic bonds.
Nitrogen and phosphorous will tend to form covalent bonds with each other.
Nonmetals, such as sulfur and carbon, tend to form covalent bonds with one another. Also, the difference in electronegativity between sulfur and carbon is 0.03, which means they form a nonpolar covalent bond with one another.
Carbon will almost always form bonds with other carbon atoms, and that is part of what makes it such a useful element.
if a compound is bonded with four other atoms to satisfy its valancy then it is said to be a covalent compound.
Tellurium is an element and will tend to form ionic bonds but can also form covalent bonds. Any element on its own is always nonpolar.
Covalent. Non-metals tend to share electrons
The bond closest in nature to a covalent bond is C-Cl, because carbon and chlorine are both nonmetals, and nonmetals tend to form covalent bonds with each other. The other choices would be closest in nature to an ionic bond because they are all metals bonded with a nonmetal. Metals and nonmetals tend to form ionic bonds with each other.
Na will be part of ionic bond
oxygen normally forms a convalent bond with one or two other oxygen atoms. as well as oxygen atoms forming oxygen molecules, oxygen atoms tend to form bonds with most of the other elements to form oxides. oxygen atoms on there own are rare. as for phosphorous.........

According to two Wikipedia articles, phosphorus and iodine can form phosphorus triiodide (PI3) and diphosphorus tetraiodide (P2I4). These compounds are made from the covalent bonding between the phosphorus and iodine atoms. Nonmetals tend to form covalent bonds with other nonmetals.
Atoms with high electronegativity tend to for covalent bonds.
