The nucleus
Like all other atoms it contains three subatomic particles, they are Protons, Neutrons and Electrons.
A molecule contains atoms e.g. water (H2O) The atoms, ( hydrogen and oxygen, and all other atoms) contain protons, neutrons in the nucleus of the atoms and electrons in energy shells around the nucleus. Protons, neutrons and electrons are sub-atomic particles.
The "subatomic" particles in atoms are usually considered to be only protons, neutrons, and electrons, although these may contain sub-subatomic particles such as quarks and gluons. Every atom of xenon contains 54 protons and 54 electrons, because 54 is the atomic number of xenon. Every atom of xenon also contains neutrons. The lightest naturally occurring and radioactively stable isotope of xenon is Xe-124. Since the mass number is the sum of protons and neutrons, the total of protons, electrons, and neutrons for this isotope is 124 + 54 or 178. The number of particles for any other isotope of xenon may be found by adding the mass number to the atomic number.
Yes. The atomic nucleus is positively charged because it contains protons which are positively charged subatomic particles.
as far as i know aluminum is a molecule not an atom. The aluminum atom has a valence of 3, what its chemical structure is depends on what it combines with.
A vacuum
You think prpbable to electrons.
Like all other atoms it contains three subatomic particles, they are Protons, Neutrons and Electrons.
Molecules, made up of atoms, made up of subatomic particles. At least as far as we know.
Yes. The atomic nucleus is positively charged because it contains protons which are positively charged subatomic particles.
Nucleons (neutrons and protons collectively)
Atoms are made of a nucleus, which contains subatomic particles called neutrons and protons, and electrons, which orbit the nucleus in certain areas.
The nucleus of an atom contains only protons and neutrons. Electrons orbit the nucleus.
Helium has two neutrons and two protons in its nucleus.
The three subatomic particles found in an atom are the Protons, Neutrons, and Electrons. But the subatomic particles found in the nucleus of an atom are the Protons, and Neutrons. The Electrons surround the nucleus and take up most of the volume.
nucleus....contains protons & neutrons
Hydrogen. This is because its atomic structure contains one proton, one neutron (or in some cases, no neutrons) and one electron, which are nearly massless particles, due to their size. This lack of subatomic particles results in little to no gravitational pull on it, causing it to float upwards much faster than other gases, such as neon or nitrogen.
