What does each of the facts shown above tell you about the element on the periodic table?
Answer (2)
The atomic number of a chemical element (also known as its proton number) is the number of protons found in the nucleus of an atom of that element, It can be used to determining which group the element belongs to in the periodic table. Therefore, atomic number is the correct answer.
The atomic number of an element is the key to its identity on the periodic table, indicating the number of protons and electrons in a neutral atom. This number helps to understand the element's placement in the periodic table, its chemical properties, and its behavior in reactions. Additionally, the number of neutrons can lead to the existence of isotopes, affecting stability and reactivity.
