# When you add the number of protons and neutrons together you get?

## When you add the number of protons and neutrons together you get?

For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.

## What is represented when protons and neutrons are added?

The number of protons in the nucleus of an atom is the same as the atomic number of that atom. If you add together the number of protons and neutrons, you get the atomic mass number of that particular atom.

When one proton and one neutron is combined what element will it produce?

Deuterium is an isotope of hydrogen that is composed of one proton, one neutron, and one electron. The nucleus of deuterium is composed of a proton and a neutron. The symbol for deuterium is given as 2H. The atomic number of deuterium is 1 and the mass number is 2.

What element is formed when a proton and neutron come together?

Within about 3 minutes after the Big Bang, conditions cooled enough for these protons and neutrons to form hydrogen nuclei. This is called the era of nucleosynthesis.

### Why does adding a proton change the element?

Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom’s atomic number. So, adding or removing protons from the nucleus changes what element that atom is!

### How are protons and neutrons similar and different?

Although similar in mass, protons are positively charged, while neutrons have no charge. In these atoms, the positive and negative charges cancel each other out, leading to an atom with no net charge. Protons, neutrons, and electrons: Both protons and neutrons have a mass of 1 amu and are found in the nucleus.

What is proton electron and neutron?

Summary. Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom’s nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge (they are neutral).

How does a proton and neutron bind?

Protons and neutrons are made up of smaller subatomic particles. When protons or neutrons get close enough to each other, they exchange particles (mesons), binding them together. Although the strong force overcomes electrostatic repulsion, protons do repel each other.

#### Why are protons and neutrons attracted to each other?

The strong nuclear force pulls together protons and neutrons in the nucleus. At very small distances only, such as those inside the nucleus, this strong force overcomes the electromagnetic force, and prevents the electrical repulsion of protons from blowing the nucleus apart.

#### What changes when you add a proton?

Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom’s atomic number. For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium.

What does adding a neutron do?

Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that atom.

What happens to the number of neutrons when you add a proton?

Since the atomic mass consists of protons and neutrons, adding a proton would add one unit to the atomic massguessing that the number of neutrons doesn’t change. What is a direct consequence of the number of protons and neutrons in an atom’s nuceuls?

## Can we remove a proton from the nucleus of an atom?

Yes We can remove a proton or a neutron from the nucleus of an atom by supplying energy equal to or greater than the seperation energy of the neucleon to be removed. where M (0,1)= neutron mass, M (Z, N)= mass of nuclide and M (Z, N-1) = mass of the lighter isotope resulting from the removal of the neutron.

## How are electrons attracted to the nucleus of an atom?

The nucleus of an atom consists of bound protons and neutrons (nucleons). The negatively-charged electrons are attracted to the positively-charged protons and fall around the nucleus, much like a satellite is attracted to the gravity of the Earth.

Do Protons break apart when they are bound together?

Once they are bound, it takes considerable energy to break them apart. To add protons or neutrons, the nucleons either have to be moving at high speed or they need to be forced together under great pressure. Although the strong force overcomes electrostatic repulsion, protons do repel each other.
