Elements are pure substances that cannot be broken down into simpler substances by chemical means. They are made up of one type of atom, whereas materials can be mixtures of different elements or compounds. Elements are organized in the Periodic Table based on their unique properties and atomic structures.

Do all materials contain oxygen and silicon?
Not all materials contain oxygen and silicon. These elements are commonly found in minerals and rocks, but there are many other types of materials, such as metals, plastics, and organic compounds, that do not contain oxygen and silicon as primary components.
Does dysprosium combine with other elements?
Yes, dysprosium can form chemical compounds with other elements. It is commonly found in combination with other elements in minerals such as xenotime and monazite. Dysprosium is used in various alloys and as a dopant in materials for electronics applications.
What types of elements are useful for dating materials?
Radioactive elements such as carbon-14, uranium, and potassium-argon are commonly used for dating materials. The decay rates of these elements provide a way to estimate the age of the material based on the amount of the element remaining. Other methods, such as dendrochronology and thermoluminescence, can also be used for dating certain materials.
How do IA and IIA differ the other Group A elements?
base in my experience.... because of the gravity of the earth...
What are low and high z materials?
In materials science, "low z" refers to elements with low atomic number, such as carbon, silicon, and oxygen. "High z" materials, on the other hand, refer to elements with high atomic number, such as lead, uranium, and gold. Low z materials are typically lighter and more abundant, while high z materials are denser and often have unique properties due to their higher atomic number.

What are most of the elements made of?
Elements are not made of other elements. They are made of protons, neutrons, and electrons. They all differ in configuration.
What are the 100 most common elements made of?
Elements are not made of other elements. They are made of protons, neutrons, and electrons. They all differ in configuration.
How many grams are in 140mil?
140 ml of water is 140 grams,- other materials will differ.
WHEN DO ELEMENTS DIFFER FROM EACH OTHER?
The difference is made by the number of protons, specifi for each element.
Is the far few materials are elements than are not elements?
The far fewer materials are elements than are not elements. Elements are pure substances made up of only one type of atom, while most materials are combinations of different elements (compounds) or mixtures of elements and compounds. There are 118 known elements, but an infinite number of possible combinations of those elements.
Are atoms of the same elements exactly alike?
yes other than the electron count may differ.
What is the key difference that causes the atoms of one element to differ from the atoms of the other elements?
number of protons
How are stones seen?
With the eyes! Stones are seen as raw materials, as primary components of some building materials, as unwanted elements of other items...
How does the composition of most minerals differ from the pure element?
Minerals (other than elemental minerals) are combinations of elements.
How can living organisms and materials on earth be composed of just a few elements?
living things need other elements but very small amounts
