Phosphorus is a non-metal that burns easily. It ignites in air at around 30°C (86°F) and can produce bright flames when it burns, often emitting white smoke. Its reactivity makes it useful in various applications, including the production of fertilizers and matches. However, it must be handled with care due to its flammability and toxic properties.
Magnesium is a metal when we say burning of magnesium it means formation of its oxide with liberation of heat and light.
non-metal.
Aluminium
That is right, phosphorous is a non metal. The group of 17 nonmetals can be identified on a periodic chart very easily. The non metals include everything in the very rough triangle formed by Carbon, Radon and Helium. Hydrogen is clear at the top left, but it too has the distinction of being a non metal.
Magnesium is a metal. When it burns it forms compounds, to which the terms metal and nonmetal are generally not applied.

oxygen is a non metal element. Atomic mass of it is 15.99.
Aluminium
Hydrogen has 1 electron. It can easily gain or lose electron to form metal or non metal
Sulfur is a non-metal that can burn with a blue flame. When ignited, sulfur reacts with oxygen in the air to produce sulfur dioxide gas, which burns with a characteristic blue flame.
Non-metals are dull (or they are not shiny as metals).

Francium has the lowest electronegativity and fluorine the highest.

a poor conductor of electricity is never a metal because metals have low ionization enthalpies and thus electrons can be easily mobilized.
