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
Which particles in an atom can increase or decrease in number without changing the identity of the element?
Neutrons
What is the number of neutrons in an atom called?
The number of neutrons in an atom is called the neutron number.
When don't neutrons equal number of protrons?
Neutrons do not always equal the number of protons in an atom when there are isotopes present. Isotopes are atoms of the same element with different numbers of neutrons. This affects the atomic mass of the atom without changing its chemical properties.
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.

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 is the total number of protons and neutrons in an atom's nucleus. It indicates the atom's mass and helps identify isotopes of an element.
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.
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.
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 is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom affects the atomic mass of an element. Neutrons contribute to the overall mass of the atom but do not affect its chemical properties.
Is the mass number of an atom equal to the atomic number?
No, the mass number of an atom is not equal to the atomic number. The mass number is the total number of protons and neutrons in an atom's nucleus, while the atomic number is the number of protons in the nucleus. The mass number can be greater than or equal to the atomic number, depending on the presence of neutrons in the nucleus.
What is the sum of protons and neutrons in an atom?
Mass number!:)
Which particles in an atom can increase or decrease in number without changing the identity of the element?
Neutrons
