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
What else can I help you with?
The nucleus is made up of what?
The nucleus is primarily made up of protons and neutrons, which are tightly packed together in the center of an atom. The nucleus also contains other subatomic particles like electrons moving around it in specific energy levels.
What are the 3 particals that make up an atom?
An atom is made up of protons, neutrons and electrons. The protons and neutrons form a nucleus where the majority of the mass is; the electrons are in orbit around the nucleus.
How do you describe the structure of an atom?
The current model of the atom shows that the atom is mainly empty space. There is a small part of the atom, called the nucleus, which contains most of the mass of the atom and all of its positive charges. Electrons orbit this nucleus in different energy levels.
Describe the nucleus of an atom?
The nucleus is an organelle, enclosed within the cell that stores the cell's DNA (genes and chromosomes) and coordinates the cell's activities. The nucleus is the control center for the cell.
What is the size of the Nucleus?
Assuming you're talking about the nucleus of an atom, the nucleus is very small relative to the atom's volume as a whole. However, it makes up nearly all of an atom's mass, because it contains all the protons and neutrons. So, relative to the total atom, the nucleus is very small and very dense.
What is the part of the atom that makes up the mass of the atom?
the nucleus of the atom
What part of an atom makes up the mass of an atom?
the nucleus
What makes up an atom's nucleus?
Within an atom's nucleus are protons and neutrons. The mass of a atom is consisted majorly from protons and neutrons. If your looking further into the atom's nucleus you'll run into "quarks".
A proton neutron and electron are in the nucleus of an atom?
yes they are what makes up the atom
What makes up the middle part of the atom?
The middle part of the atom is called the nucleus, which is composed of protons and neutrons. Protons have a positive charge, while neutrons have no charge. The nucleus makes up the majority of the atom's mass.
What parts of an atom makes up all the mass of an atom?
The nucleus is the part of an atom that contains practically all its mass. In the nucleus, you can find the proton and neutron. The number of electrons, which move about the nucleus, is equal to the number of protons.
What makes up the centre of an atom in chemistry?
The center of the atom is the nucleus formed from protons and neutrons.
How much of an atom volume does the nucleus make up?
The nucleus of an atom only makes up a tiny fraction of the total volume of the atom, typically less than 1%. The majority of an atom’s volume is composed of the electron cloud surrounding the nucleus.
What makes up up the center of the atom?
The nucleus. Consists of protons and sometimes neutrons.
What makes up of the atoms?
The nucleus makes up most of the mass and the other things in the atom make up the rest.
What makes up most of the volume of an atom.?
Empty space makes up most of the volume of an atom. The nucleus (protons and neutrons) make up most of the mass.
Are the proton atoms and the neutron atoms in the nucleus?
yes they are what makes up the atom
