nonaromatic rings
A ring that does not have a loop of pi electrons but is not antiaromatic is said to be nonaromatic. A compound whose molecule contains one of more nonaromatic rings is called a nonaromatic compound. A ring whose pi system contains a 4n number of electrons but avoids being antiaromatic by deviating from planarity is nonaromatic.
eg:
Experimentally, 3 exists in the following nonplanar conformation, known as the tub conformation, in which no two adjacent double bonds are on the same plane. Thus, there is no loop of pi electrons in the ring in 3; 3 is nonaromatic.
A ring whose pi system contains 4n + 2 number of electrons but is forced to deviate from planarity is nonaromatic. Thus, 10is nonaromatic.
To find whether a ring is aromatic, antiaromatic, nonaromatic, or none of the above, use the following flow chart.
Ruby cannot be considered either as it is not an element. It is primarily made of corundum, which is a compound of aluminum (a metal) and oxygen (a nonmetal).
2 non metallic elements = Nitrogen and Hydrogen
The two main types of luster are metallic and non-metallic. Metallic luster refers to the shine of metals, while non-metallic luster includes categories like vitreous (glassy), pearly, greasy, and earthy.
A sharpened pencil lead is non-metallic. It is typically made of graphite, which is a non-metallic element.
Silicon is an element, not a compound or mixture. It is a non-metallic chemical element with the atomic number 14 and symbol Si.
it is not metallic SO2 is a non-metallic compound
Neither. It is classified as a compound.
Chlorine is a nonmetal but its is an element, not a compound.
Gypsum is a salt (a compound made of both metallic and non-metallic elements).
No, water is not an element, it is a compound.
Salt is an ionic compound consisting of a metal and a non metal.
Ruby cannot be considered either as it is not an element. It is primarily made of corundum, which is a compound of aluminum (a metal) and oxygen (a nonmetal).

Borax is a mineral that is a compound of the element boron. It is not a metal. Boron is a metalloid, rather than a metal.
A seashell is considered nonmetallic as it is primarily composed of calcium carbonate which is a compound commonly found in nature.
compound because it is made up of two elements, nickel andchloride
Baking soda, also known as sodium bicarbonate, is a compound made up of the metal sodium and non-metal elements carbon, hydrogen, and oxygen. Sodium is the metallic element while carbon, hydrogen, and oxygen are non-metallic elements.
