How do elements differ from compounds, and in what ways are they similar?
Elements are substances made up of only one type of atom, while compounds are substances made up of two or more different types of atoms chemically bonded together. Elements are the simplest form of matter, while compounds are more complex. Both elements and compounds are pure substances, meaning they have a fixed composition and properties.
Which element is probably like oxygen why?
Sulfur is probably like oxygen because it shares similar chemical properties and can form compounds with other elements in a similar way. Both elements have a tendency to react with other elements to form stable compounds.
Are both elements and compounds essential for life?
Yes, both elements and compounds are essential for life. Elements are the basic building blocks of all matter, while compounds are formed when elements combine in specific ways. In living organisms, elements are used to form compounds that are necessary for various biochemical processes to occur.
What do elements in the same group in the periodic table have in common?
They have the same number of valence electrons, or electrons in the outer electron shell. This allows them to react with certain elements.
Why elements share similar characteristics?
Elements share similar characteristics because they have the same number of electrons in their outermost energy level, which determines their chemical properties. This similarity is due to their placement in the periodic table, where elements in the same group have the same number of valence electrons. These shared characteristics allow elements to react in similar ways and form similar types of compounds.

Why are there more materials than elements?
Because the elements can combine in many ways to form compounds, and compounds can be mixed in many differed ways. Moreover, some elements occur in different forms. The elements carbon and hydrogen alone combine for form thousands of compounds.
Do compounds have very similar properties from those of the elements that make it?
no

How are compounds and mixtures similar?
A mixture contain two or more compounds.

Can compounds composed of different elements have similar properties?
Yes. (Salts are a good example of this.)
Why do you think scientists need shorthand ways of writing elements and compounds?
because it is easier
Is it true when element chemically combine the usually form compounds that have properties that are similar to those of the uncombined elements?
No: The compounds more often have very different properties from those of the elements that form them.
How do elements relate to compounds?
Chemical compounds are formed from chemical elements.
