Which mass number or atomic number determine what element an atom is?
The identity of the element is determined solely by the atomic number, which is the number of protons.
Which particle determines the atomic number of an element?
The atomic number of an element is determined by the number of protons.
What information could you use to determine the atomic number of an unknown element that has the mass number of 22?
To determine the atomic number of an unknown element with a mass number of 22, you would need to know the number of protons in the nucleus of the element. Since the mass number is the sum of protons and neutrons, subtracting the number of neutrons from the mass number would give you the atomic number. This is because the atomic number represents the number of protons in an element's nucleus.
What is the atomic number and atomic mass number of the element that is formed in the following nuclear reaction that takes place in the sun?
The atomic number is 2, and the atomic mass is 4 (helium)

To determine the atomic number of an element with a mass number of 22, you would need the number of protons in the nucleus. Since the mass number is the sum of protons and neutrons, subtracting the number of neutrons (mass number) from the mass number gives you the number of protons (atomic number).

How do you determine neutrons in element?
subtract the atomic number from the mass number
What does a mass number determine?
mass number = number of protons + number of neutrons DIFFERENT FROM ATOMIC MASS atomic mass = weighted average of all the isotopes of that element

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.
What information could you use to determine the atomic number of an unknown element that has a mass number of 22?
the only element with a mass number of 22 is sodium (Na) which has an atomic number of 11. This is because the atomic number only represents the number of protons in the nucleus, while the mass number represents the number of protons and neutrons in the nucleus.
If an element has a mass number of 208 and an atomic number of 83 how many neutrons does the element have?
To determine the number of neutrons, subtract the atomic number from the mass number. In this case, 208 - 83 = 125 neutrons.
How do scientists determine the number of neutrons and isotopes in an atom?
Atomic mass minus atomic number. This is rather simplified but the atomic mass of an element is the total of all the protons, neutrons, and electrons in an atom. Each proton and neutron has an atomic mass of approximately 1 AMU (atomic mass units) while an electron has an atomic mass of about 0.0005 AMU. So, you don't need to worry about the electrons. The atomic number of an element is simply the number of protons in the atom. So, atomic mass (number of protons and neutrons) minus atomic number (number of protons) equals number of neutrons in an atom.
How can one determine the mass of an element in a compound?
To determine the mass of an element in a compound, you can use the chemical formula of the compound and the atomic mass of the element. Multiply the atomic mass of the element by the number of atoms of that element in the compound, then add up the masses of all the elements present in the compound to find the total mass.
