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 is a Nucleus of a helium atom?

The nucleus of a helium atom contains two protons and two neutrons.


The nucleus of an atom contains 12 protons and 12 neutrons while the necleus of another atom contains 12 protons and 16 neutrons what are the atoms?

I believe it is two isotopes of an element. Because an isotope is the amount of protons. with a different number of neutrons in the nucleus. hopefully this will help :)


The nucleus of an atom contains what two particles?

nucleus....contains protons & neutrons


Which subatomic particles are located in the nucleus of a He-4 atom?

In a He-4 atom, the nucleus contains two protons and two neutrons. The protons have a positive charge, while neutrons are neutral.


A tritium atom contains how many neutrons protons and electrons?

Tritium is 3H, so it has one proton, one electron (in the non-ionized state) and two neutrons.


What are atoms that have the same element but different neutrons?

IsotopesThe number of protons in the nucleus of an atom determines the element. The number of neutrons can vary. If two atoms of the same element have a different number of neutrons in their nuclei, they are isotopes of that element.


If a hydrogen atom has 2 neutrons is that a isotope?

Yes, a hydrogen atom with 2 neutrons is an isotope, specifically known as tritium. While the most common hydrogen isotope has no neutrons (protium), tritium contains one proton and two neutrons. Isotopes of an element have the same number of protons but different numbers of neutrons, resulting in different atomic masses.


Protons and neutrons are located in the nucleus of the atom?

The atom is composed of two parts, the nucleus, which contains the Protons and neutrons, and is positively charged; and the negative electrons surrounding it.


What is an atom with two neutrons protons and electrons?

If you build an atom using two protons, two neutrons and two electrons you would build an atom of Helium. To be more-precise, this would create Helium-4 the common isotope of Helium.


What element contains two large molecules?

By definition, an element is a single atom, not a molecule.


The nucleus of a helium atom contains four subatomic particles how many neutrons does the helium atom have?

Helium has two neutrons and two protons in its nucleus.
