Sulfur is an element of the periodic table that is not considered a metalloid.
<h3>What is sulfur?</h3>
Sulfur is a chemical element of the periodic table that has the following characteristics:
- Atomic number 16
- S symbol
- Sulfur is classified as a nonmetal
- It has a yellow color
<h3>What are metalloids?</h3>
Metalloids are a set of chemical elements of the periodic table that are characterized by having an intermediate behavior between metals and non-metals, in terms of ionization energies and binding properties.
It is not easy to distinguish them from true metals. They conduct electrical current better than non-metals, but they are not good conductors like metals. In addition, they are usually very varied in their shape and coloration.
The list of metalloids includes the following elements:
- Boron (B)
- Silicon (Si)
- Germanium (Ge)
- Arsenic (As)
- Antimony (Sb)
- Tellurium (Te)
- Polonium (Po)

Answer:
The weight-average molar mass of polystyrene is 134,160 g/mol.
Explanation:
Molar mass of the monomer styrene ,
, M=104 g/mol
Given , number average molar mass of the polymer , M'= 89,440 g/mol
Degree of polymerization = n

The weight-average molar mass = 
Molar mass dispersity is ratio of weight-average molar mass to the number average molar mass of the polymer.



The weight-average molar mass of polystyrene is 134,160 g/mol.
Explanation:
Can you please make the question more precise..
Thanks..
Any physical matter that is obtained or made from plants, animals, or the ground without undergoing a chemical process is called a natural material. This is a true statement.
<h3>Features of natural materials</h3>
Natural materials are the physical matters that are made from plants, animals and ground(environment) which has not been subjected to any chemical processes for modification.
But any natural material that has undergone any chemical process which has been designed and manufactured to fulfil a particular purpose is called a synthetic material.
Therefore, any physical matter that is obtained or made from plants, animals, or the ground without undergoing a chemical process is called a natural material.
