Are the number of protons always equal to the number of neutrons?

No, in fact, they rarely are equal. There are different forms of the same type of atom. For example, there are three isotopes of Hydrogen, an element that has one proton. Hydrogen-1 has no neutrons. Hydrogen-2 has one neutron. Hydrogen-3 has two neutrons.

∙ 11y agoNo, the number of protons in an element gives its type, such as Carbon (6 protons) or Oxygen (8 protons), while the number of neutrons can vary as isotopes of an element, such as Carbon-12 and Carbon-14, which have 6 and 8 neutrons, respectively.

∙ 11y agoNeutrons don't have an equal number unlike protons and electrons because an element is not determined by its amount of neutrons and elements can go on with more or less neutrons without changing the element, with isotopes though, neutrons can change forms, and protons and neutrons are not always the same, when an element is an ion, it will have lost or gained electrons.

∙ 10y agono because proton have a positive charge and nuetron has no charge
Wiki User
∙ 15y agobecause they do not need to be equal. the only reason protons and electrons are equal numbers is because an atomic structure needs to be neutrally charged to remain stable.
Wiki User
∙ 9y agoAn ion is formed.
A positive ion if there are fewer electrons than protons.
A negative ion if there are more electrons than protons.
Wiki User
∙ 13y agoThis case is of isotopes.this occurs when the number of neutrons changes in an atom that is the number of neutrons is not equal to the number of electrons of an atom.
Wiki User
∙ 12y agoNo. Elements have isotopes that vary in neutron number. Carbon 12 ( 12 neutrons ) and carbon 14 ( 14 neutrons ) as an example.

∙ 9y agoIons are formed. It involves loss and gain of electrons.

How is the mass number related to the number of protons and neutrons and atoms has?
The mass number of an element is equal to the number of protons plus the number of neutrons.
Is the atomic number of an atom equal to the number of protons or neutrons or electrons in the nucleus?
No, atomic number equals the number of protons.The number of neutrons is NOT specific to an element, and various atoms of the same element can have different numbers of neutrons - these are called isotopes.
What represents the number of protons and neutrons in an atom of uranium?
The number of protons is equal to the number of electrons and the atomic number. The number of neutrons is different for each isotope (number of neutrons = atomic mass of the isotope [or mass number] - number of protons).
What is equal to the total number of protons and neutrons?
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
What is the atomic number always equal to?
The number of protons in the nucleus of each atom that has the atomic number.
Does the number of neutrons always equal the number of protons?
No
An equal number of protons and neutrons typically results in an atom that is?
Often, but not always, atoms with an equal number of protons and neutrons in the nucleus are stable and not radioactive.
What subatomic particle is always equal in neutral atoms?
protons and electrons will always be = number
Why must the number of protons and neutrons be equal?
The number of protons and neutrons is not equal. The equality is not a rule.
Do neutrons always equal the number of elecrons?
Electrons are equal to the number of protons and the atomic number. To find the number of neutrons you must subtract the atomic number from the mass number.
What are atoms with mor neutrons than protons?
Atoms with more protons than neutrons are simply isotopes of an element. Atoms of an element always have the same number of protons. However, the number of neutrons can vary and can be higher, lower, or equal to the number of protons.
Does the number of protons in an atom of an element always equal its atomic weight?
atomic weight = mass of protons + mass of neutrons
Do electrons equal the sum of the number of neutrons and protons in an isotope?
No. The number of neutrons has no affect on the number of protons and electrons.
Do atoms have equal electrons and protons?
Not all atoms have an equal number of protons and neutrons. They can, but they don't have to. Helium, for example, has two of each, but carbon (always with 6 protons) can have 6, 7, or even 8 neutrons. The more neutrons, the more likely it is to be radioactive. The number of protons and neutrons gives the atomic weight of an atom. All of the various amounts of neutrons that an element can have are called isotopes of that element.
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
The mass number of an element is equal to the total number of?
The mass number is the average atomic mass of all the isotopes that are found in nature.
What is the symbol of barium and number of neutrons?
The symbol is Ba. The number of neutrons equal the number of protons.
