nucleus....contains protons & neutrons
Protons and neutrons; these particles contain quarks and gluons.
The term nucleus has two main meanings in science. The center of a cell contains a cell nucleus, which can be defined as an organelle which contains the genetic material of the organism. And the center of an atom contains the atomic nucleus, which can be defined as the part of the atom which contains protons and/or neutrons (all atoms except for the lightest hydrogen isotope contain both protons and neutrons).
There are only two stable subatomic particles, Protons and Neutrons. Protons: Positive charge, 1amu The "atomic number" of an element gives the number of protons in its nucleus. Neutrons: No charge, makes up rest of the atomic mass, 1amu each The nucleus of every element contains one or more of each kind of stable subatomic particle, except for hydrogen which has ONE proton, but no neutrons
every atom has not 2 parts but 30 parts! WOW!
The nucleus contains nearly all the cell's DNA. * In the nucleus are chromosomes. Each chromosome consists of one (or, after replication, two) molecule of DNA, with proteins, most of which are histones, along its length. One region of the nucleus is the nucleolus, in which most of the genes for synthesizing ribosomal RNA are found.
Helium has two neutrons and two protons in its nucleus.
An atom's nucleus contains two types of particles. The first is protons, which carry a negative charge. The second type of particle is the neutron, which has a neutral charge. These two particles are about equal in mass.
In a He-4 atom, the nucleus contains two protons and two neutrons. The protons have a positive charge, while neutrons are neutral.
The nucleus of a helium atom contains two protons and usually two neutrons, giving it an atomic mass of 4 atomic mass units. It is positively charged due to the protons it contains, while the electrons orbit around the nucleus in the electron cloud.
There're two particles in the atom nucleus (protons and neutrons)
The center of an atom is made up of two particles: protons and neutrons. Protons have a positive electric charge, while neutrons have no charge. Together, they make up the nucleus of an atom.
The nucleus of a helium atom contains two protons and two neutrons.
An atom's nucleus contains two types of particles. The first is protons, which carry a negative charge. The second type of particle is the neutron, which has a neutral charge. These two particles are about equal in mass.
The nucleus of an atom is located at the center of the atom. It contains protons and neutrons, which are held together by strong nuclear forces. The nucleus makes up the majority of the atom's mass and has a positive charge due to the protons it contains.
Protons and neutrons are the two particles that are in the nucleus of an atom. Electrons orbit around the atom
Protons and neutrons are in the nucleus, and electrons are in the cloud that surrounds it.
The term nucleon signifies any particle that is present inside the nucleus of an atom. We know that the nucleus of any atom contains only two particles which are proton and neutron whereas electron are present outside the nucleus revolving around it. Hence, electron is not a nucleon.
