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.
The number of protons in the nucleus is determined by the element's atomic number, which is unique to each element. It is the same as the number of electrons in a neutral atom of that element. You can find the atomic number on the Periodic Table.
The atomic number of an element, i.e. the element's number on the periodic table is the also the number of protons that element has. For example, Oxygen is number 8 on the table and has 8 protons.
To find the number of protons in an atom, you look at the Atomic Mass of the element. The atomic mass is usually located right above the element symbol. It is always a whole number. The atomic number is the number of protons and electrons in an atom.
The number of protons determine what atom it is and vice versa.
For example oxygen has 16 protons because its atomic weight is 16.
If an atom doesnt have 16 protons, it cant be oxygen.
Use the periodic table to find out the atomic weights of diffrent atoms.

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 in an atom is equal to its atomic number, which can be found on the periodic table.
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.
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.
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.
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.
What does the number of protons in a atoms's nucleus determine?

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.
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?
The number of protons and neutrons in the nucleus determine the atomic mass for an element. The atomic mass is typically calculated by adding the number of protons and neutrons together.
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.
