Magnesium is a metal because it displays the properties of metals. These properties are displayed below:
1.) Magnesium is shiny.
2.) Magnesium is malleable and ductile.
3.) Magnesium has a relatively high melting/boiling point.
4.) Magnesium is hard.
Furthermore, magnesium is placed in group II which is towards the left side of the Periodic Table. Elements placed towards the left side of the periodic table are metals. The metallic properties of elements decreases from left to right.
Sodium chloride is a compound, not a chemical element.
some paper is. but its mostly made out of plastic from fish guts.
non metal
non-metal
All elements are either metal or non-metal or metalloids.
yes
the answer is 2,8,1
NO2 is a non-metal oxide. Nitrogen dioxide (NO2) is composed of nitrogen and oxygen, both of which are non-metals on the periodic table. Non-metal oxides typically form acidic solutions when dissolved in water, as they react with water to produce acids. In contrast, metal oxides tend to form basic solutions when dissolved in water.

A non-metal.
Oxygen is a non-metal. It is a reactive gas that is essential for sustaining life and is found in the non-metal group on the periodic table.
Sodium chloride is a compound, not a chemical element.
Neon is a non-metal because it is a noble gas located in group 18 of the periodic table with a full valence shell of electrons, making it stable and unreactive.
