What is true about the atomic nuclei?
The atomic nucleus contain protons and neutrons.
What element is a very dense metal with an atomic mass of 207.2?
The element you are referring to is lead (Pb). It is a very dense metal with an atomic mass of 207.2.
In Rutherfords gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
What form of energy that holds atomic nuclei together called?
The strong force holds atomic nuclei together.
Is nuclei an element on the Periodic Table?
No. "Nuclei" is the plural of "nucleus". In chemistry this usually denotes the atomic nucleus, a tiny but very dense structure of protons and neutrons in the centre of an atom (or ion) that carries most of its mass. The number of protons in the nucleus of any atom indicates the type of chemical element it belongs to, the number of neutrons determines the isotope type.
What is true about the atomic nuclei?
The atomic nucleus contain protons and neutrons.
Which of these statements is true of atomic nuclei.they are very dense.. they contain electrons..they are mostly empty space..they have a neutral charge?
Atomic nuclei are very dense, as they contain protons and neutrons tightly packed together. They do not contain electrons, as electrons orbit around the nucleus. Although nuclei are very small in comparison to the overall size of an atom, they are not mostly empty space. Nuclei typically have a positive charge due to the presence of protons.
What statement is true of atomic nuclei?
Atomic nuclei are positively charged and contain protons and neutrons. The number of protons in the nucleus determines the element, while the number of neutrons can vary within isotopes of the same element. Nuclei are held together by the strong nuclear force, which overcomes the electromagnetic repulsion between positively charged protons.
What element is a very dense metal with an atomic mass of 207.2?
The element you are referring to is lead (Pb). It is a very dense metal with an atomic mass of 207.2.
Is atomic nuclei required in a chemical reaction?
No, atomic nuclei is not required for a chemical reaction.
In Rutherfords gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
What is a dead star with the density of an atomic nuclei called?
A dead star with the density of an atomic nuclei is called a neutron star. Neutron stars are incredibly dense and are composed mostly of tightly packed neutrons. They form when massive stars explode in a supernova and their cores collapse under gravity.
What form of energy that holds atomic nuclei together called?
The strong force holds atomic nuclei together.
What the combining of atomic nuclei is?
The combination of two light atomic nuclei to form a heavier nucleus is called fusion.
What is nuclaer stability?
That refers to atomic nuclei being stable - not disintegrating, or at least not disintegrating very quickly.
Is nuclei an element on the Periodic Table?
No. "Nuclei" is the plural of "nucleus". In chemistry this usually denotes the atomic nucleus, a tiny but very dense structure of protons and neutrons in the centre of an atom (or ion) that carries most of its mass.

What type of nuclear reaction releases energy through the combination of atomic nuclei, unlike fission reactions which involve the splitting of atomic nuclei?
The type of nuclear reaction that releases energy through the combination of atomic nuclei is called fusion. This is different from fission reactions, which involve the splitting of atomic nuclei.
