Protons are positively charged particles found in the nucleus of an atom. The number of protons in the nucleus determines the element's atomic number. Neutrons are neutral particles also found in the nucleus, and together with protons, they determine the Atomic Mass of the element.

What two factors determine the atomic mass of an elements?
neutrons and protons
In periodic table of elements it is the sum of the number of protons and neutrons of an atom.?
The sum of protons and neutrons is the atomic mass.
What particles make up the mass of an atom?
The number of protons
Atomic masses of any two elements contain the same number of?
protons and neutrons. This is because the atomic mass of an element is calculated by adding the number of protons and neutrons in the nucleus of an atom. The number of protons determines the element's identity, while the number of neutrons affects its stability.
If there is a difference between a substance's atomic number and its atomic mass and which measure must be the larger number?
The atomic number represents the number of protons in an atom, while the atomic mass represents the sum of protons and neutrons. Generally, the atomic mass is larger than the atomic number for most elements since it includes both protons and neutrons.

In periodic table of elements it is the sum of the number of protons and neutrons of an atom.?
The sum of protons and neutrons is the atomic mass.
Why is the number of neutrons the atomic number?
the number of neutrons is not the atomic number. The atomic number of an atom is the atoms number of protons. The number of protons is same as the number of electrons. The number of protons is used as the atomic number so that the elements can be easily organized in polarity size and bonding probability.
What particles make up the mass of an atom?
The number of protons
What is the atomic number of an atom that has 2 protons and 3 neutrons?
5: The mass number of an isotope is always the sum of the numbers of protons and neutrons in a nucleus of elements of the isotope.
What is the formula for finding the amount of neutrons in an element?
The formula for finding the amount of neutrons in an element is: Number of neutrons = Atomic mass number - Atomic number. The atomic mass number represents the sum of protons and neutrons in the nucleus of an atom, while the atomic number represents the number of protons. Subtracting the atomic number from the atomic mass number gives you the number of neutrons.
How do you count the number of neutrons and protons in an atom?
The number of protons in an atom is its atomic number, which you can find on the periodic table. To calculate the number of neutrons, subtract the atomic number from the atomic mass listed on the periodic table.
How do you find the atomic number and atomic mass for an element on the periodic table?
Elements are arranged according to according to atomic number. It is the number of protons. Atomic mass is sum of protons and neutrons.
Atomic masses of any two elements contain the same number of?
protons and neutrons. This is because the atomic mass of an element is calculated by adding the number of protons and neutrons in the nucleus of an atom. The number of protons determines the element's identity, while the number of neutrons affects its stability.

The atomic number represents the number of protons in an atom, while the atomic mass represents the sum of protons and neutrons. Generally, the atomic mass is larger than the atomic number for most elements since it includes both protons and neutrons.
What is the number of protons electrons and neutrons in n-14?
Nitrogen-14: 7 Protons, 7 Electrons, 7 Neutrons To work this out in the future for other elements: Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number Hope this helps!
What is the number of neutrons for a specific element equal to?
The average number of neutrons that a specific element has is equivilent to the element's atomic mass minus the that elements atomic number. For example Helium has 2 neutrons because its atomic mass (4) minus the atomic number (2) is 2.
