the number of protons determine what the substance is. if the number of protons in an atom change, the substance made of that atom changes too.
The number of protons determines the element, and is the same as its atomic number.
The atomic number is the number of protons in the atom. The number of protons is what determines the element the atom is. This makes the atomic number very important in determining what the atom is.
The number of protons in an atom's nucleus determines its chemical identity.
The atomic number corresponds to the number of protons in an atom. Hydrogen is the first element on the Periodic Table of Elements because it only has one proton. The number of protons in an atom and the number of neutrons in an atom are what make atoms different.
The atomic number of an atom is determined by the number of protons it has.
The number of protons determines the element, and is the same as its atomic number.

The number of protons in an atom is its atomic number.
Atomic number of a atom is same as the number of protons of the same atom
The atomic number of an atom is equivalent to the number of protons in its nucleus.
The number of protons in an atom's nucleus determines its chemical identity.
The atomic number corresponds to the number of protons in an atom. Hydrogen is the first element on the Periodic Table of Elements because it only has one proton. The number of protons in an atom and the number of neutrons in an atom are what make atoms different.
The atom identity is given by the number of protons.
The number of protons in an atom's nucleus is the Atomic number.
The atomic number of an atom is determined by the number of protons it has.
Uranium is a heavy chemical element, but not the heaviest; the aspect is due to a greater number of protons and neutrons.
the number of protons found in the nucleus of an atom
