The sum of Which two things is the atomic number in an element?
It is not the sum of two things, but only the number of protons found in the nucleus of the atom. The atomic mass is the total number of neutrons and protons in the nucleus.
What are the 2 particles that make up the nucleus of an atom?
Protons and neutrons compose the nucleus of an atom. Most of the mass of an atom exists in the nucleus. Other smaller sub atomic particles such as quarks exist, but are usually not addressed until advanced physics or chemistry classes.
The nucleus of a helium atom contains four subatomic particles how many neutrons does the helium atom have?
Helium has two neutrons and two protons in its nucleus.
Two particles make up the center of an atom?
The center of an atom is its nucleus which contains Protons and neutrons, but there are also some other particles.
What are two main regions of an atom?
Nucleus and electrons
What two parts of an atom is located in the nucleus?
Protons and neutrons are in the nucleus, and electrons are in the cloud that surrounds it.
What are the two particles that make up the nucleus of an atom?
Protons and neutrons.
What is a Nucleus of a helium atom?
The nucleus of a helium atom contains two protons and two neutrons.
What are helium atom nucleus?
The nucleus of a helium atom is composed of two protons and two neutrons. Alpha particles have the same composition as the nucleus of a helium atom.
What are two parts that make up the nucleus of a lithium atom?
Protons and Neutrons
The sum of Which two things is the atomic number in an element?
It is not the sum of two things, but only the number of protons found in the nucleus of the atom. The atomic mass is the total number of neutrons and protons in the nucleus.
What are two particles in an atom?
There're two particles in the atom nucleus (protons and neutrons)
What force holds an atom to its nucleus?
its proton and its nucleus will have two protons so its electron and atom
What particles make up nucleus A?
The two particles that make up the nucleus of an atom are the proton and the neutron. The proton has a positive charge, and the neutron doesn't have a charge.
What particles of atom are found in the nucleus?
The particles of the atom in the nucleus are the protons and neutrons. Protons carry a positive charge and neutrons have no charge. These two make up the vast majority of an atom's mass. Electrons, with their negative charges, orbit the nucleus in different energy levels.
Where is a proton in the atom?
In the nucleus of the atom there are two things: protons and neutrons. Protons have a positive charge and neutrons no charge. Protons are subatomic particles found in the central unit on an atom: the nucleus. It's positively charged.
What are the 2 particles that make up the nucleus of an atom?
Protons and neutrons compose the nucleus of an atom. Most of the mass of an atom exists in the nucleus. Other smaller sub atomic particles such as quarks exist, but are usually not addressed until advanced physics or chemistry classes.
