12. the atomic number of an element is the number of protons in it's nucleus. The mass number is the number of protons+neutrons. Therefore the element has (32-20)12 protons.

When you subtract the atomic number from the atomic mass of any element you get what?
By subtracting the atomic number from the atomic mass of an element, you obtain the number of neutrons in its nucleus. The atomic number represents the number of protons in the nucleus, and the atomic mass includes both protons and neutrons, so the difference gives you the number of neutrons.
Which solid element has 135 neutrons in its nucleus?
The element with 135 neutrons in its nucleus is Xenon, which has an atomic number of 54.
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 protons and neutrons relate to an elements atomic number?
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.
Which atomic property is different in each isotope of an element?
The number of neutrons in the nucleus is different in each isotope of an element. Isotopes of an element have the same number of protons (atomic number) but different numbers of neutrons, leading to variations in atomic mass.

How do you calculate the number of neutrons an element has in its nucleus?
You need to find the atomic number, and the atomic mass. The atomic number i the number of PROTONS in the nucleus, the atomic mass, or mass number, is the number of PROTONS and NEUTRONS in the nucleus. To find the number of neutrons you subtract the atomic number from the mass number.
Which solid element has 135 neutrons in its nucleus?
The element with 135 neutrons in its nucleus is Xenon, which has an atomic number of 54.
Is the atomic weight of an element is equal to the number of protons minus the number of neutrons?
No, the atomic weight of an element is not equal to the number of protons minus the number of neutrons. Atomic weight is the average weight of an element's isotopes taking into account their abundance, which includes the sum of the protons and neutrons in the 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.
What is the atomic mass in an element?
The atomic mass in an element is the total number of protons and neutrons in an atom's nucleus.
How do protons and neutrons relate to an elements atomic number?
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.
Which atomic property is different in each isotope of an element?
The number of neutrons in the nucleus is different in each isotope of an element. Isotopes of an element have the same number of protons (atomic number) but different numbers of neutrons, leading to variations in atomic mass.
How many neutrons and electrons are in the nucleus of an atom?
The atomic number of a chemical element is equal to the number of electrons or protons. The number of neutrons = Atomic weight of an isotope (rounded) - atomic number of the element (or the number of protons)
How are the atomic mass and the atomic number different?
The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of the number of protons and neutrons in the nucleus. Atomic number determines an element's identity, while atomic mass affects its atomic weight and isotopes.
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 is the difference between the atomic number and atomic mass?
The atomic number represents the number of protons in an atom's nucleus. It determines the element's identity. Atomic mass is the average mass of an atom of an element, taking into account its isotopes and their abundance. It is the sum of the protons and neutrons in the nucleus.
