Question

What are the characteristics of the atom of an element, according to the atomic theory? What differences can you infer between the atoms of different elements? ​

Answer 1

Atomic Number

Neutral atoms of an element contain an equal number of protons and electrons. The number of protons determines an element's atomic number (Z) and distinguishes one element from another. For example, carbon's atomic number (Z) is 6 because it has 6 protons.

Answer 2

Answer:

Atoms themselves are composed of protons, neutrons, and electrons. Each element has its own atomic number, which is equal to the number of protons in its nucleus. Isotopes of an element contain different numbers of neutrons. Elements are represented by an atomic symbol.

The atoms of different elements differ in the number of protons that are found in their nuclei. The number of protons in an atom's nucleus is called the atomic number. All atoms of the same element have the same atomic number.
