MATTER - PROPERTIES AND TRANSFORMATION: Chemistry of Elements - Phosphorus

Why is phosphorus considered a reactive non-metal?

It is a good conductor of electricity.

It forms basic oxides.

It readily gains or shares electrons to complete its octet.

It has a high electronegativity.

Which physical property contributes to the danger of white phosphorus?

Its high melting point.

Its low density.

Its luminescence (glowing in the dark).

Its insolubility in water.

What is the characteristic appearance of white phosphorus?

Red powder.

Black shiny solid.

Waxy, yellowish-white solid.

Transparent crystal.

In a plentiful supply of air, phosphorus reacts to form.

P_{4 (s)} + 3O_{2 (g)} → P₄ O_{6 (g)}.

P_{4 (s)} + 6Cl_{2 (g)} → 4PCl_{3 (l)}.

P_{4 (s)} + 5O_{2 (g)} → P₄ O_{10 (g)}.

P_{4 (s)} + 10Cl_{2 (g)} → 4PCl_{5 (s)}.

In a limited supply of air, phosphorus reacts to form.

P_{4 (s)} + 5O_{2 (g)} → P₄ O_{10 (g)}.

P_{4 (s)} + 3O_{2 (g)} → P₄ O_{6 (g)}.

P_{4 (s)} + 6Cl_{2 (g)} → 4PCl_3(l).

P_{4 (s)} + 10Cl_{2 (g)} → 4PCl_{5 (s)}.
