yes it is
The nucleus of an atom is the central part of an atom containing practically all the mass of the atom. The nucleus is composed from protons and neutrons.
Most of the mass in an atom is found in the nucleus, which contains the protons and neutrons.
The most mass of a atom is located in the nucleus, where the protons and the neutrons are located.
There are two types of particles in the nucleus of an atom, which are the Protons and the Neutrons. The number of particles in the nucleus depends what is the element. For example, Oxygen has 8 protons and 8 neutrons in the nucleus and Phosphorus has 15 protons and 16 neutrons in the nucleus.
An atom's mass is located entirely in the nucleus. In the nucleus, there are protons and neutrons. Electrons are located outside of the nucleus, but because the mass of an electron is so insignificantly small, it's not counted when determining the total mass.
An atom's mass is concentrated in its nucleus, which is located in the center of the atom. Protons and neutrons within the nucleus are responsible for its mass; the electrons, which are located outside of the nucleus, don't contribute to the mass of the atom.
The nucleus, made up of protons and neutrons, contains most of an atom's mass.
The nucleus of an atom is the central part of an atom containing practically all the mass of the atom. The nucleus is composed from protons and neutrons.
The mass of an atom is concentrated in the nucleus, which is made up of protons and neutrons.
When calculating the mass of an atom, you add the mass of the protons and the neutrons. This is the nucleus of the atom. The electrons are small enough to be ignored except in the most delicate calculations.
It is the nucleus. Mass of electrons is too small
The atomic mass of an atom is the combined mass of the protons and neutrons in the nucleus.
Most of the mass in an atom is found in the nucleus, which contains the protons and neutrons.
The number of neutrons and protons in the nucleus of the atom.
An atom is comprised of protons, neutrons, and electrons. The electrons take up the most space as they orbit the nucleus. But nearly all of the mass of the atom is found in the nucleus of the protons and neutrons.
Nucleus. Composed of Protons and neutrons. Can be sub-divided further but you probably don't have to know that. (quarks and muons and such.)
Most of the mass in an atom is in the nucleus. The protons and neutrons are about the same weight, 1 amu. The elecrtons are 1/1840 of the mass of an proton. Neutrons are 2000 times heavier than electrons and protons have an equal mass of neutrons
