Most of the atom's mass is concentrated in the nucleus.
The nucleus, made up of protons and neutrons, contains most of an atom's mass.
Isotope.
Electrons orbit the Nucleus. the Nucleus contains protons and neutrons. The proton contains positive in charge (+) and Neutrons are neutral. (=) However, electrons are the ones with negative charge. (-)
The first two statement are false. The other one is true. There are electrons outside the nucleus, but they are much lighter than the particles in the nucleus.
Because more than 99 % from the mass of an atom is concentrated in the nucleus (protons + neutrons).
the nucleus
The atom's central region is called the nucleus. It contains protons and neutrons, which are the particles that make up the majority of an atom's mass. Electrons orbit around the nucleus in different energy levels.
The nucleus contains the mass.
The dense region at the center of an atom, consisting of protons and neutrons, is called the atomic nucleus. It contains the majority of the atom's mass and is positively charged due to the presence of protons. Electrons orbit around the nucleus in the electron cloud.
The centre of an atom is called the nucleus, and it contains only protons and NEUTRONSbut no electrons at all.
NUCLEUS ---------------------------------------------------------------------- In an atom, there are three subatomic particles. Two of them are found in the central region known as the nucleus: the proton, which is positively charged and neutron that does not have a charge. Another region, containing the negatively charged electron, is known as a cloud, an electron cloud if you want.
The nucleus, made up of protons and neutrons, contains most of an atom's mass.
The nucleus is the region of the atom where most of the atom's positive charge and almost all of its mass is concentrated. It contains protons and neutrons tightly packed together. The electrons orbit around the nucleus in different energy levels.
Almost all of the volume of an atom has no mass.
the denser part of an atom is the nucleus. about 99% of the mass of an atom is concentrated within the atom.
An assembly of protons and neutrons within an atom is called a nucleus. It is the central part of an atom that contains most of the mass of the atom and is positively charged due to the protons it contains.
Most of the mass in an atom is found in the nucleus, which contains the protons and neutrons.
