Is the number of protons equal to the number of neutrons in an atom?

The number of neutrons in an atom CAN be equal to the number of protons and electrons, BUT IT IS NOT ALWAYS. You can find the number of neutrons in an atom by subtracting the atomic number from the mass number. The number is often the same among the lighter elements, but the ratio of neutrons to protons quickly grows larger than one (on average) as you go further along the periodic table.

99.999867% of helium, for instance, has the same number of these nucleons. For almost all elements above atomic number 21 (which would be scandium), the neutrons are more common.

∙ 13y agoNot necessarily, this is true of some of the isotopes of lighter elements, but most isotopes have more neutrons than protons.
Wiki User
∙ 13y agonot usually, a standard atom will contain the same amount of electrons and PROTONS, not neutrons
Wiki User
∙ 11y agoNo, most atoms have different numbers of protons and neutrons.
Wiki User
∙ 12y agoNo. The number of protons equals the number of electrons in a neutral atom.

What equals the number of neutrons plus the number of protons in an atom?
The mass number is a whole number that is equal to the sum of protons and neutrons in an atom. Mass number is represented by the letter (A) orA= Z + N (Z) represent the atomic number or the number of protons in the nucleus.
How many protons electrons and neutrons are in Ag?
The number of protons in a atom is equal to the atomic number, therefor Ag has 47 protons. The number of protons and neutrons in an atom is equal to the atomic mass, therefor (108-47= 61) Ag has 61 neutrons. The number of electrons is equal to the number of protons therefor Ag has 47 electrons.
Is the number of protons equal to the number of ions in a uncharged atom?
No, there is no requirement that the number of protons equal the number of neutrons. In fact, this gives rise to the various isotopes of a given element (Different isotopes will have different numbers of neutrons, while sharing the same number of protons). The number of protons is what generally defines an element. By being "uncharged" the atom is understood to have the same number of electrons as protons. Neutrons, being neutral, do not carry charge.
What is the mass number of an atom equal to?
The mass number of an atom is equal to the number of protons and neutrons that are in the nucleus of the atom. Atoms are the basic units of a chemical element.
How do you find the number of neutrons protons and electrons in an atom if the atom is neutral?
The number of electrons in an atom is always equal to the number of protons in that same atom. Since the atomic mass of a periodic element equals the weight of the atoms protons AND its neutrons, the following equation can be used to calculate the number of any given particle in an atom: number of neutrons = atomic mass - atomic number
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.
Is the atomic number of an atom is equal to the number of protons or neutrons in the nucleus?
Protons
What equal to the number of protons and neutrons in an atom?
mass number
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 equals the number of neutrons plus the number of protons in an atom?
The mass number is a whole number that is equal to the sum of protons and neutrons in an atom. Mass number is represented by the letter (A) orA= Z + N (Z) represent the atomic number or the number of protons in the nucleus.
How many protons electrons and neutrons are in Ag?
The number of protons in a atom is equal to the atomic number, therefor Ag has 47 protons. The number of protons and neutrons in an atom is equal to the atomic mass, therefor (108-47= 61) Ag has 61 neutrons. The number of electrons is equal to the number of protons therefor Ag has 47 electrons.
Is an atom neutral if it has a greater number of electrons than protons?
False. An atom is neutral if it has an equal number of protons and neutrons
What number is the atomic mass equal to?
Atomic mass is the number of protons and neutrons in an atom.
Does the number of neutrons equal the mass number?
no, the mass number is number of protons in an atom, 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.
How do you find the number of electrons in an atom if you know the number of protons and neutrons?
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.
Atom does not have to have equal numbers of protons and?
An atom does not have to have equal numbers of protons and neutrons.
