Answer: Most elements don't have formulas.
Explanation: They exist as single atoms, witn no bonds to another atom. A few element do exist as molecules, such as )2 and N2, but they are bonded to the same atom. There are no different elements.
in 1 to 2 sentences explain why a structural formulas are good for depicting polymers
Answer:
they explain the properties and structure of the compound which empirical molecular formulars cannot explain
The structural formulas are good for depicting polymers because polymers are the chemical compounds attached to the long chain with ac other which is impossible to represent other than the structural formula.
What are structural formulas?The structural formulas are the graphic representation or diagrammatical representation of the structure of any chemical formula in organic and inorganic chemistry they are mostly used.
In Polymers, they are long chains of chemicals compound can be shown diagrammatically or graphically to understand the attachment t of the bonds within them which signifies the physical properties too.
Therefore, polymers are the chemical compounds attached to the long chain with ac other which is impossible to represent other than the structural formula which is why structural formulas are good for depicting polymers.

7) Explain how the atomic number of an element identifies the element.
Answer:
The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. ... The sum of the atomic number Z and the number of neutrons N gives the mass number A of an atom.
Answer:
Atoms of each element contain a characteristic number of protons. In fact, the number of protons determines what atom we are looking at (e.g., all atoms with six protons are carbon atoms); the number of protons in an atom is called the atomic number.
