Why nitrogen is gas and others are solid?
When you go down a group, size of elements increases and hence polarizability also increases. Due to increased polarizability, London Dispersion Forces acting between molecules keep on rising going down a group giving rise to solid state of elements. Hence nitrogen is gas and other family members are solids.
Why nitrogen is a gas?
Molecular nitrogen is a colorless, odorless, tasteless, and inert gas at normal temperatures and pressures. About 78\% of Earth’s atmosphere is nitrogen. The strong triple-bond between the atoms in molecular nitrogen makes this compound difficult to break apart, and thus nearly inert.
Why does phosphorus exist as P4 but nitrogen as N2 gas?
It is because – N2 contains a pi bond between two N atoms. But P4 does not. It lacks the pi bond and it is because unstable pi tend to overlap among two P atoms.
Why does phosphorus behave differently from nitrogen?
P-P single bonds are stronger than N-N single bonds, in other words phosphorus prefers to form many single bonds rather than a triple one with itself. Phosphorus can expand its valence shell to hold more than eight electrons, whilst nitrogen cannot.
Why is nitrogen diatomic and phosphorus polyatomic?
Nitrogen because of its small size and high electronegativity forms pπ-pπ moltiple bonds. Therefore, it exists as diatomic molecule, N≡N. Phosphorous, due to to its large size and low electronegativity cannot form pπ-pπ multiple bonds with itself.
Does phosphorus exist as gas?
White Phosphorus and Related Molecular Forms It consists of tetrahedral P4 molecules, in which each atom is bound to the other three atoms by a single bond. This P4 tetrahedron is also present in liquid and gaseous phosphorus up to the temperature of 800 °C, at which point it starts decomposing into P2 molecules.
Is nitrogen a gas liquid or solid?
Nitrogen has a low melting and boiling point and is a gas at room temperature. The Earth’s atmosphere is made up of 78\% nitrogen.
Is Phosphorus a gas?
phosphorus (P), nonmetallic chemical element of the nitrogen family (Group 15 [Va] of the periodic table) that at room temperature is a colourless, semitransparent, soft, waxy solid that glows in the dark.
Is P4 a solid liquid or gas?
Phosphorus is a chemical element with the symbol P and atomic number 15….

Why is phosphorus written P4?
Answer: Phosphorus can form a P4 white phosphorus tetrahedron because it can form three bonds. It can make a tetra-atomic P4 molecule by sharing valency electrons with three other P atoms to complete its octet. …
Why nitrogen and phosphorus have similar bonding characteristics?
Since phosphorus is just below nitrogen, we can expect nitrogen and phosphorus to have some similar properties. They are nonmetals and have similar properties when making compounds. Both are abundant on Earth and are cycled through the environment through the nitrogen cycle and the phosphorus cycle.
Why nitrogen and phosphorus are typical non metals?
Answer: In group 15, nitrogen and phosphorus behave chemically like nonmetals, arsenic and antimony behave like semimetals, and bismuth behaves like a metal. Due to their higher electronegativity, the lighter pnicogens form compounds in the −3 oxidation state.
Why does nitrogen and phosphorus form a gas?
There is relatively little attraction between one nitrogen molecule and another, so they move independently and form a gas. In phosphorus, the atoms do not pair up, they bond to their neighboring atoms, thus forming a network of bonding that holds the atoms together into a solid.
What is the difference between n2n2 and phosphorus?
N2 is a gas (all exterior electrons that can rotate so not bonding at reasonably low temperature). Phosphorus cannot create compact all exterior electrons, so it is usually solid. Nitrogen has only 1s2 in the shell below them. That means that electrons can settle into various structures, including three (3) in one hemisphere for a triple bond.
Why is NIT nitrogen a gas?
Nitrogen is a gas because it is simple diatomic molecule with triple bond between the two nitrogen atoms. In all of these structures a phosphorus atom is attached with more than two phosphorus atoms (4 in white and polymeric structures in red and black). Due to this extensive bonding phosphorus is found in solid state.
Why is phosphorous found in solid state?
Phosphorous is found in different allotrpic forms as white, red and black phosphorus. In all of these structures a phosphorus atom is attached with more than two phosphorus atoms (4 in white and polymeric structures in red and black). Due to this extensive bonding phosphorus is found in solid state.
