Cells obtain their four main elements—carbon, hydrogen, oxygen, and nitrogen—primarily through the intake of nutrients from their environment. These elements are found in organic molecules like carbohydrates, proteins, lipids, and nucleic acids, which cells consume from their surroundings. Additionally, plants absorb carbon dioxide from the air and water from the soil, while all organisms utilize metabolic processes to incorporate these elements into cellular structures. Ultimately, the cycling of matter within ecosystems ensures the availability of these essential elements.

What is the relationship between the length of a side and the surface area-to-volume ratio of a cell?
As size increases, the s/v ratio decreases-- the s/v ratio of a cubic cell 1mm on a side is 6, but the s/v ratio of a cubic cell 3mm on a side is only 2.
What groups make up the main block elements?
The s and p blocks make up the main-group elements, which are also known as representative elements.
Which two blocks of the periodic table make up the main - group elements?
Main group elements include elements (except hydrogen) in groups 1 and 2 (s-block), and groups 13 to 18 (p-block).
Why are the main-group elements called the representative elements.?
S- and p- electrons fill in a regular repeating manner. Hence, elements in the s- and p-blocks have predictable patterns that represent a wide range of properties. Therefore, the s- and p-block elements are called the main-group, or representative, elements. Non-metals, Alkali, Halogens
Why are the main group elements the representative?
S- and p- electrons fill in a regular repeating manner. Hence, elements in the s- and p-blocks have predictable patterns that represent a wide range of properties. Therefore, the s- and p-block elements are called the main-group, or representative, elements. Non-metals, Alkali, Halogens
What are the main elements in a bicycle tire?
Bead(s), casing, tread.
What types of orbitals contain the valence electrons in the main group elements?
The valence electrons in main group elements are typically found in the s and p orbitals. Group 1 and 2 elements have valence electrons in s orbitals, while groups 13-18 elements have valence electrons in both s and p orbitals.
Why are the main group element called the representative element?
S- and p- electrons fill in a regular repeating manner. Hence, elements in the s- and p-blocks have predictable patterns that represent a wide range of properties. Therefore, the s- and p-block elements are called the main-group, or representative, elements. Non-metals, Alkali, Halogens
What is a body cell that starts with s and is 4 letters?

Are the elements Cu a representative elements?
Yes, copper (Cu) is considered a representative element. Representative elements also called main-group elements, are the elements found in the s and p blocks of the periodic table. Copper is located in Group 11 and period 4 of the periodic table, making it a representative element.
What is the name of elements whose outermost s and p sublevels are filled?
All the noble elements to the far right of the periodic table have their s and P sublevels in their valence shell filled, hence they are nonreactive.
How many elements fit into each of the four blocks of the periodic table?
4: the s-block, the p-block, the d-block, and the f-block. there is an theoratical g-block but its not counted because its theoratical lol.
