The atomic number refers to the number of proton in a particular atom.
As a matter of fact, number of proton = number of electrons in an atom.
The number of electron changes as the atom forms ion.
The number beneath carbon in the periodic table indicates its atomic number. Atomic number is the number of protons in the nucleus of an atom of that element.
Carbon dioxide (CO2) does not have an atomic number because it is a compound, not an element. The atomic number refers to the number of protons in the nucleus of an atom of an element. Carbon (C) has an atomic number of 6.
Carbon dioxide is a compound, not an element. It does not have an atomic number.
Atomic number
hydrochloric acid does not have an atomic number. Only elements have atomic numbers and hydrochloric acid is a compound composed of two non-metal elements: hydrogen and chlorine, as you might have guessed by the name. However: Hydrogen's atomic number is 1 and Chlorine's atomic number is 17
The atomic number indicates the number of protons in an atom of a particular element. The atomic number must be an integer (counting number), and is unique to that specific element.
Ammonia does not have an atomic number, as it is a molecular compound composed of nitrogen and hydrogen atoms. The atomic number refers to the number of protons in an atom's nucleus, and since ammonia is a compound, it does not have a single atomic number.
The number beneath carbon in the periodic table indicates its atomic number. Atomic number is the number of protons in the nucleus of an atom of that element.

Chromium has the atomic number of 24.
It indicates the atomic number of that element.
Carbon dioxide (CO2) does not have an atomic number because it is a compound, not an element. The atomic number refers to the number of protons in the nucleus of an atom of an element. Carbon (C) has an atomic number of 6.
Antimony trisulphide Sb2S3 is a compound and does not have an atomic number. Antimony does and so does sulfur - but not the compound
doesn't have one, its a compound. only elements have atomic numbers, which is the number of protons the element has.
It is a compound. Only atoms have atomic number. Elements have their own atomic number.
Carbon dioxide is a compound, not an element. It does not have an atomic number.
Hydrogen chloride is not an element; it is a compound and has no atomic number!
