Answer 1

Elements are made of atoms with identical atomic numbers, are represented by chemical symbols, and cannot be separated into simpler substances by ordinary chemical or physical means.

Step-by-step explanation:

Elements are fundamental forms of matter that are made up of atoms with the same atomic number and cannot be broken down into simpler substances by ordinary chemical means. The following statements describe the elements:

• Elements are made of atoms with the same atomic number.
• Elements cannot be separated using ordinary chemical means.
• Elements may be represented by chemical symbols.

Contrary to some of the other statements provided, elements cannot be separated using physical means and are not made of two or more different types of atoms; this description fits compounds rather than elements. Additionally, molecules are formations of two or more atoms, but molecules consisting of more than one element are specifically called compounds.
