Do all atoms of a given element contain the same number of protons and the same number of neutrons?

No. Each element may have several different numbers of neutrons in an atom (resulting in isotopes) and there are many of these numbers that are shared, e.g. potassium and calcium both commonly have 20 neutrons.

∙ 12y agono i don't believe so. from what i remember in science class the neutrons in an atom are equal to the amount of protons. i may be wrong, but that's what i remember. so, if an atom has 10 protons, it should have 10 neutrons.

This is true for atoms of a low atomic number, but not true for atoms with larger atomic numbers. The major isotope of helium, for example, has two protons and two neutrons. But U-238, the major isotope of uranium, has 92 protons and 116 neutrons.
It has been observed that the more nucleons are in an atom's nucleus, the higher percentage of them must be neutrons in order for the nucleus to be stable. Scientists do not yet have a theory to explain this, although they do have hypotheses.

∙ 13y agoYes that is true Every atom of a given element does have the same number of protons.
Wiki User
∙ 11y agoNo, only atoms of the same type have the same number of protons, and some atoms of the type have different numbers of neutrons, this are called isotopes. Hope this helps.

∙ 13y agoThey do not however they usually contain the same balance between the two, as far as I know.
Wiki User
∙ 11y agoAll the atoms of a given element contain the same number of protons. However they may have different neutrons and such species are known as isotopes.

What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
The main difference between isotopes of the same element has to dowith the number of?
The difference between isotopes of the same element have to do with the number of neutrons present in the nucleus of the atom. Isotopes are atoms of an element that contain the same number of protons, but different numbers of neutrons and therefore different mass.
Is the atomic weight of an element is equal to the number of protons minus the number of neutrons?
Atomic weight of an element is the number of protons plus neutrons in the nucleus, atomic number is the number of protons only.
What is a similarity and a difference between isotopes of an element?
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
How many protons and neutrons does a nucleus of an atom contain?
Each element has a different number of protons and neutrons. So it changes for each element.
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
What do different isotopes of a particular element contain the different number of?
Isotopes of a chemical element have a similar number of protons but a different number of neutrons.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
How many protrons and neutrons does boron contain?
5 Protons, 6 Neutrons. For future reference, the protons is the atomic number (right above the element symbol) To get the neutrons you subtract the atomic mass (underneath the symbol) by the number of protons. You have to round this number.
What does the atomic number of an atom made of?
An atomic nucleus contain protons and neutrons; protons and neutrons contain quarks and gluons.
The main difference between isotopes of the same element has to dowith the number of?
The difference between isotopes of the same element have to do with the number of neutrons present in the nucleus of the atom. Isotopes are atoms of an element that contain the same number of protons, but different numbers of neutrons and therefore different mass.
Approximately how many protons and neutrons are in the element uranium?
All the isotopes of uranium contain 92 protons; the number of neutrons is variable for each isotope: Number of neutrons = Atomic weight of the given isotope - 92
An element's atomic mass number is?
It is about neutrons and protons. The total of neutrons and protons.
What are the element number of neutrons?
Number of Neutrons = Mass number - Number of Protons
What element has the same number of neutrons and protons?
Atoms having the same number of protons and neutrons make up the same element.
What are the number of protons neutrons and electrons in an element?
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
