No, nitrogen and phosphorus would not typically form a covalent bond with each other. Both elements can form covalent bonds, but they are more likely to form bonds with other elements due to differences in electronegativity and chemical properties.
There's not really a "group of double bonds." There are five elements that'll do it - carbon, nitrogen, oxygen, phosphorus and sulfur.
No, metallic bonds only form between the atoms of a metal. Nitrogen and phosphorous are both nonmetals, and would be expected to form a covalent bond. However, I do not know if nitrogen and phosphorus bond with one another, since they are in the same group.
Elements like carbon, nitrogen, and oxygen can form triple covalent bonds. These elements have enough valence electrons to share three pairs of electrons, resulting in the formation of a stable triple covalent bond.
Carbon forms 4 bonds, nitrogen forms 3, oxygen forms two and hydrogen forms one.
Nitrogen has five valence electrons, as it is in group 15 of the periodic table. Similarly, phosphorus, also in group 15, also has five valence electrons. This allows both elements to form three covalent bonds, contributing to their chemical reactivity.
The properties of nitrogen are more similar to the properties of phosphorus. Nitrogen and phosphorus are both nonmetals with similar chemical reactivities and tendencies to form covalent bonds. Neon, on the other hand, is a noble gas with very different properties compared to nitrogen.
Nitrogen has 5 valence electrons, as it is in group 15 of the periodic table. Similarly, phosphorus also has 5 valence electrons for the same reason, being in the same group. Both elements can form three covalent bonds by sharing these valence electrons.
tetrahedral
the elements that form covalent bonds are on the right hand side of the periodic table and usually have either 4,5,6,7 electrons in their outer most shell (valence shell). eg carbon, nitrogen, oxygen and flourine. :)
Copper primarily bonds with elements such as oxygen, sulfur, and chlorine to form compounds. Depending on the oxidation state of the copper ion, it can bond with various other elements like carbon, nitrogen, and phosphorus to form a wide range of compounds.
I think it's covalent as the the two elements are both nonmetallic.
