The number of protons and neutrons added together gives the Atomic Mass number, nucleon number or often simply the mass number".

This is DIFFERENT from the (relative) atomic mass, once called atomic weight, which is the average mass of the naturally occurring isotopes of an element in a sample relative to 1/12 th mass of carbon-12.

What do protons and neutrons equal?

Protons and neutrons together make up the atomic nucleus. Protons are positively charged particles, while neutrons have no charge. The number of protons in an atom determines its atomic number, while the total number of protons and neutrons together determine its atomic mass.


Is this statement correct atoms are made up of nucleus and electrons composed of protons whose number is called the atomic number and neutrons whose numbers added together make the mass number?

It's close, but an atom is made of a nucleus and electrons. The nucleus is made of protons and neutrons. The number of protons equals the atomic number of the element, and the atomic mass is the number of protons plus neutrons.


Does the nucleus of an atom have protons neutrons electron?

no, they don't. instead they make up the nucleus of the atom. protons and neutrons are made of quarks, which are held together by gluons.which means that the nuceuls and electrons together make the atom.


What is the mass number and how do you calculate it?

The mass number is the total number of protons and neutrons in an atom's nucleus. To calculate the mass number, simply add the number of protons and neutrons together in the nucleus of an atom.

How is the nucleus related to the periodic table?

The nucleus contains the protons and neutrons. The number of protons determines the atomic number of the element and the number of protons and the number of neutrons together determine the atomic mass.


What particles are added together to determine atomic mass?

The atomic mass of an atom is determined by the sum of the number of protons and neutrons in its nucleus. Protons have a positive charge, and neutrons have no charge. The total number of protons and neutrons in an atom's nucleus is called its mass number.

How do protons and neutrons relate to an elements atomic number?

Protons are positively charged particles found in the nucleus of an atom. The number of protons in the nucleus determines the element's atomic number. Neutrons are neutral particles also found in the nucleus, and together with protons, they determine the atomic mass of the element.

What part of the nucleus determine the atomic mass for an element?

All parts of the nucleus, protons and neutrons if any, contribute to the atomic mass. The total number of protons and neutrons in an atom is its isotope mass number.


What element is the number of protons and neutrons in the nucleus?

All elements have neutrons and protons within the nucleus.


The mass number is used to calculate the number of what?

The number of protons and neutrons in the nucleus


What is the arrangement of zirconium's protons and neutrons?

Zirconium has 40 protons and typically 51 neutrons in its nucleus, giving it a mass number of around 91. The protons are positively charged particles while the neutrons are neutral, together making up the nucleus of the zirconium atom.


Does the nucleus of an atom have protons neutrons electron?

Most stable types of nuclei have an number of protons and an number of neutrons?

Most stable nuclei have a roughly equal number of protons and neutrons, which helps to balance the forces that hold the nucleus together. This balance of protons and neutrons helps minimize the nucleus's potential energy, making it more stable.


What is the mass number and how do you calculate it?

The mass number is the total number of protons and neutrons in an atom's nucleus. To calculate the mass number, simply add the number of protons and neutrons together in the nucleus of an atom.
