How does the atomic number describe the number of protons in the nucleus of an atom?
The atomic number is equal to the number of protons in the nucleus of an atom.
Does the atomic number describe the number of protons in one atom of an element?
Yes it does.
To find the number of neutrons in an atom you would subtract what?
You would subtract the atomic number from the mass number.
What is the atomic number of 30Ar?
The atomic number of Argon is 18. So 30 of them the Atomic Number would be 540.
What does the atomic number describe about an atom?
The number of protons in the nucleus of an atom
Why is the 17 in 35 Cl not needed to describe chlorine?
The number 17 in 35Cl represents the atomic mass of chlorine, which is the sum of protons and neutrons in the nucleus. Since the atomic number (number of protons) is sufficient to uniquely identify an element, the number 17 is not needed to describe chlorine.

No. Atomic number is always a whole number. This would be the atomic mass.
What other characteristic sub-atomic particle can the atomic number describe for a non iodized atom?
The atomic number is the number of protons in an atom. If an atom is not ionized, the number of electrons must be the same as the number of protons.
To find the number of neutrons in an atom you would subtract what?
You would subtract the atomic number from the mass number.
What is the difference between the atomic number and the valence number of an atom?
Describe the reactivity of halogens
