The number of protons in an atom determines the chemical identity of that atom. (And only that, by the way.) We use the atomic number to state the exact number of protons in all atoms of a given element. Hydrogen has the atomic number 1 because every atom of hydrogen has exactly one proton. Also, every atom with exactly one proton is hydrogen. Helium is atomic number 2, and the same thing applies. All helium atoms have exactly 2 protons, and all atoms with exactly 2 protons are helium atoms. To determine the number of protons in a given atom, look at which element it is and find it on the Periodic Table or on a list of the elements. Then find its atomic number, which will be the exact number of protons in every atom of that element.

What is the mass number for element A?
The mass number is the total number of protons and neutrons in the nucleus of an atom. To determine the mass number of element A, you need to know the number of protons and neutrons it has in its nucleus. The mass number is usually written as a superscript to the left of the chemical symbol (e.g. ^12C for carbon-12).
Determine the number of protons?
The number of protons is equal to atomic number and the number of electrons (for a neutral atom).
Which student can use their information to determine an atoms identity?
A student who knows the specific number of protons in the atom's nucleus can use this information to determine the atom's identity. The number of protons in an atom is its atomic number, which is unique for each element on the periodic table.
Atomic number equals the number of?
The atomic number is equal to the number of protons in the nucleus and in a neutral atom will also equal the number of electrons.
How do you compute atomic number?
The atomic number is equal to the number of protons in an atom's nucleus. To determine the atomic number of an element, you simply count the number of protons in the nucleus of an atom of that element. This number is unique for each element and is listed on the periodic table of elements.
What does the number of atoms in the nucleus determine?
Do you mean number of protons in a nucleus? The nucleus is part of an atom.
What do the protons of the nucleus of an atom determine?
Number of protons or the atomic number of an atom determines what is the element.
How is the nucleus related to the periodic table?
The nucleus contains the protons and neutrons. The number of protons determines the atomic number of the element and the number of protons and the number of neutrons together determine the atomic mass.
What does the number of protons in a atoms's nucleus determine?

How many protons are in the nucleus of the carbon atom?
Its electrons and protons are the same. just determine its electrons form its atomic number
Protons in the nucleus?
Protons are positively charged subatomic particles found in the nucleus of an atom. They determine the element's identity by the number of protons present, known as the atomic number. The number of protons also influences the chemical properties of the element.
What an Atoms identity?
The number of protons in the nucleus of the atom determine its identity.
What does the number of protons in a nucleaus determine of an atom?
The number of protons in the nucleus of an atom determines the atomic number of the element to which the atom belongs.
What must you know about an atom to determine its mass number?
The number of protons and neutrons in its' nucleus.
What part of the nucleus determine the atomic mass for an element?
All parts of the nucleus, protons and neutrons if any, contribute to the atomic mass. The total number of protons and neutrons in an atom is its isotope mass number.
How do scients determine the atomic number of an atom?
the atomic number is determined by the number of protons in a nucleus.
Which information would be required to determine the mass number of nitrogen?
To determine the mass number of nitrogen, you would need to know the number of protons and neutrons in its nucleus. Nitrogen has 7 protons, so the mass number can be calculated by adding the number of protons (7) to the number of neutrons in the nucleus.
