Question

4. What information does the atomic number of an element give us?

Answer 1

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. It is identical to the charge number of the nucleus.:The atomic number tells you the number of protons in one atom of an element. It also tells you the number of electrons in a neutral atom of that element. The atomic number gives the “ide The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.ntity “of an element as well as its location on the Periodic Table.

Answer 2

Answer: It gives us the identity of the element as well as the number of protons.

Step-by-step explanation:

Because the number of protons is specific for each element, we can determine what element we are looking at just by the atomic number. For example the element with the atomic number of 1 is Hydrogen, atomic number of 2 is Helium, atomic number of 3 is Lithium and so forth.
