The total number of protons amd neutrons in the nucleus determines the atoms?
HobbyLobbyJr
This is the "mass number" of the atom, indicating relative mass of an isotope.
For example uranium-235 (235U) is a lighter atom than uranium-238 (238U) because while both isotopes have 92 protons (the atomic number), the first has 3 fewer neutrons.

What determines mass number?
The mass number is the sum of neutrons and protons in the nucleus of an isotope.
An isotope is identified by its atomic mass number which is the total number of?
protons and neutrons in the nucleus of an atom. Isotopes of an element have the same number of protons but different numbers of neutrons. The number of neutrons in an atom affects its stability and often determines its nuclear properties.
What is the particle that identifies a atom?
The number of protons in an atom's nucleus determines its chemical identity.
What is mass number of an isotope?
The mass number of an element is equal to the number of protons in the nucleus, and this always determines the element in the Periodic Table. Different isotopes of the same element have differing numbers of neutrons in the nucleus, but always the same number of protons.
Total number of particles in the nucleus is called what?
There are two types of particles in the nucleus of an atom, which are the Protons and the Neutrons. The number of particles in the nucleus depends what is the element. For example, Oxygen has 8 protons and 8 neutrons in the nucleus and Phosphorus has 15 protons and 16 neutrons in the nucleus.
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 determines mass number?
The mass number is the sum of neutrons and protons in the nucleus of an isotope.
What determines the mass of an isotope?
The number of neutrons in the nucleus, the number of protons is the same for each isotope of a given element.
What determines the element that an atom belongs to?
Its atomic number. In other words the number of positive protons in the nucleus of each atom and the number of negative electrons surrounding the nucleus of each atom.
The number of neutrons plus protons in the nucleus of an atom-?
nass number is the number of neutrons plus protons in the nucleus of an atom
An isotope is identified by its atomic mass number which is the total number of?
protons and neutrons in the nucleus of an atom. Isotopes of an element have the same number of protons but different numbers of neutrons. The number of neutrons in an atom affects its stability and often determines its nuclear properties.
What is in the core of every atom?
The nucleus of the atom contains the protons and neutrons. The number of protons, called the "atomic number", determines what kind of element this is. There are almost always more neutrons in the nucleus than protons, except for very light elements. For example, hydrogen has one proton and no neutrons, while helium contains two protons and two neutrons.
What determines an attoms atomic number?
The number of protons.
What does the atomis number tell you?
Is the number of protons in an atom determines its atomic number
What is the particle that identifies a atom?
The number of protons in an atom's nucleus determines its chemical identity.
Does a nucleus have the same number of protons and electrons?
The nucleus of an atom contains only protons and neutrons; there are never any electrons in the nucleus. The number of neutrons is generally equal to or greater than the number of protons.
Protons and neutrons in the nucleus add up to give the?
The number of protons added to the number of neutrons in a nucleus give that isotope's atomic weight.
