What element can form diatomic molecules held together by triple covalent bonds?
Nitrogen is a very stable molecule and relatively unreactive, being held together by a strong triple covalent bond.
Which diatomic molecule has a triple bond between its atoms?
Explanation: Diatomic nitrogen, , contains a triple bond between the two nitrogen atoms. Since there are six electrons being shared, the bond is stronger and the atoms are being pulled closer together. Diatomic oxygen, , has a double bond, which is not as strong.
What type of bond holds diatomic fluorine together?
The halogens also form single covalent bonds in their diatomic molecules. An atom of any halogen, such as fluorine, has seven valence electrons. Its unpaired electron is located in the 2p orbital.
Which elements can form diatomic molecules?
The only chemical elements that form stable homonuclear diatomic molecules at standard temperature and pressure (STP) (or typical laboratory conditions of 1 bar and 25 °C) are the gases hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), and chlorine (Cl2).
Which elements can form diatomic molecules joined by a single covalent bond?
The halogens also form single covalent bonds in their diatomic molecules. An atom of any halogen, such as fluorine, has seven valence electrons. Its unpaired electron is located in the 2p orbital. The diatomic fluorine molecule (F2) contains a single shared pair of electrons.
What elements can form triple bonds?
Boron joins carbon and nitrogen as one of the few elements in the periodic table known to form stable compounds featuring triple bonds.
What is triple bond or triple covalent bond?
A triple bond in chemistry is a chemical bond between two atoms involving six bonding electrons instead of the usual two in a covalent single bond. Triple bonds are stronger than the equivalent single bonds or double bonds, with a bond order of three.
Is diatomic oxygen a covalent bond?
Oxygen atoms have six outer electrons so need two more for a full outer shell. The oxygen forms two single covalent bonds with the two hydrogen atoms. Examples of these are diatomic oxygen (double bond) or nitrogen (triple bond). Oxygen molecules have a double bond: two shared pairs of electrons.
Which element will form covalent bond combines with oxygen?
Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.
Is fluorine a diatomic element?
There are really only seven diatomic elements. Five of them — hydrogen, nitrogen, fluorine, oxygen and chlorine — are gases at room temperature and normal pressure.

What elements can form diatomic molecules?
How are the elements in a diatomic molecule joined?
In these molecules, two atoms are joined by one or more covalent bonds, forming a molecule with the general formula X 2. The elements found as diatomic molecules are hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), chlorine (Cl, element 17), bromine (Br, element 35), and iodine (I, element 53).
How are atoms held together in a covalent bond?
In most cases, in order to fill the outermost orbital, the electrons within it form covalent bonds with other atoms. A covalent bondthus holds two atoms close together because electrons in their outermost orbitals are shared by both atoms.
How are oxygen atoms in an O 2 molecule joined?
Oxygen atoms in the O 2 molecule are joined by a double bond. (Actually, molecular orbital picture of O 2 molecules is a great deal more complicated, but we’ll get into that in another section.) Nitrogen atoms in the N 2 molecule are joined by a triple bond. Some elements may be found in molecules of more than two atoms.
How many covalent bonds can a nitrogen atom form?
Nitrogen atoms can form up to four covalent bonds. (NH3), the nitrogen atom forms three covalent bonds; one pair of electrons around the atom (the two dots on the right) are in an orbital not involved in a covalent bond: In the ammonium ion (NH4+), the nitrogen atom forms four
