Every element has a specific number of protons, which is how an element is identified. That gives its atomic number. The number of neutrons can vary, and therefore is not useful in identifying an element.

Can you identify an atom without knowing number of neutrons in it?

Yes, and in order to find the Number of Neutrons, subtract Atomic Mass from Number Of Protons, the result will be the Number of Neutrons for that atom *No. Of Neutron=Atomic Mass - Number Of Protons


What is the number of protons and neutrons called?

The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is). The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope. The number of protons and neutrons added together is called the atomic mass.


What is an atom's mass number?

An atom's mass number is the total number of protons and neutrons in its nucleus. It is used to identify isotopes of an element since isotopes of the same element have the same number of protons but different numbers of neutrons.


What is the mass number and what does it indicates?

The mass number of an atom is the sum of the numbers of protons and neutrons in the nucleus of the atom. It also indicates the total positive charge on the nucleus.


Is The number of protons plus the number of neutrons in the nucleus of an atom known as the mass number?

Yes, the sum of protons and neutrons in the nucleus of an atom is known as the mass number. The mass number is used to identify different isotopes of an element.


What increases on a atom when neutrons do not add to the charge of an atom when its neutral?

When neutrons do not add to the charge of an atom, the number of protons remains the same, so the atomic number stays constant. However, the mass number of the atom increases because neutrons contribute to the mass of an atom without affecting its charge.


How many neutrons are in one atom?

The number of neutrons in one atom can vary depending on the element. Neutrons are one of the three main subatomic particles found in an atom, along with protons and electrons. The number of neutrons in an atom is calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom.


What does the Mass number in chemistry represent?

The mass number in chemistry represents the total number of protons and neutrons in an atom's nucleus. It is used to identify isotopes of an element, where different isotopes have the same number of protons but a different number of neutrons.


What is the number of neutrons in an atom affects the atomic what?

The number of neutrons in an atom can affect the atomic mass of an atom.


Is the mass number of an atom equal to the atomic number?

Only if the atom is hydrogen-1! The mass number of the atom is equal to the sum of the numbers of protons, which is the same as the atomic number, plus the number of neutrons. The only non-radioactive atom without neutrons is hydrogen-1.


What is the sum of protons and neutrons in an atom?

Mass number!:)


What subatomic particles could be changed without changing which element the atom is?

The element that an atom is is determined by the number of protons. The number of electrons can be changed (creating an ion), and the number of neutrons can be changed (creating an isotope), and as long as the number of protons does not change, the element that the atom is does not change.
